manner in which people obtain information. Soon after the introduction of the WWW, it was evident
that traditional browsing was totally insufficient for internet users to locate the information that
interests them. This need was covered with the development of search engines. Today, search engines
play one of the most important roles in disseminating content. Search engine optimization (SEO) is a
collection of strategies that improves a website’s presence and visibility on a search engine’s results
page (SERP). In other words, the higher and more frequently a site appears in search results, the more
visitors it will receive through the use of search engines. The importance of SEO can be understood by
the fact that many web sites today receive the majority of their web traffic through a search engine’s
organic results.
The methods that SEO includes can be divided into four major categories: keyword
research/selection, search engine indexing, on-page optimization, and off-page optimization. On-page
optimization includes the management of all factors associated directly with someone’s website (e.g.,
keywords, appropriate content, and internal link structure), while off-page optimization includes all
the efforts made away from the website such as link building or social signal strategy. Undeniably, the
world of search engine optimization has changed and evolved drastically over the years with a shift
away from traditional ranking factors towards deeper analysis, and factors such as quality, multi-form
content, and social signals. However, even though SEO has changed a lot, it remains an important part
of any digital marketing strategy.
This special issue is soliciting theoretical and case studies contributions, discussing and treating
challenges, state-of-the-art technology, and solutions on search engine optimization, including, but not
limited to, the following themes related to SEO: Theory of SEO, different types of SEO, SEO criteria
evaluation, search engines’ algorithms, social media and SEO, SEO applications in various industries,
SEO in media web sites, etc. Through invited and open call submissions, a total of five excellent articles
have been accepted, following a rigorous review process that required a minimum of three reviews
and at least one revision round for each paper.

This paper identifies the specific characteristics of Selfie Journalism in political reporting. Based on both quantitative and qualitative research, the study analyses these characteristics in the period of parliamentary elections of 2016 in Cyprus. The aim of the study is dual: first, to examine the extensive use of Selfie Journalism by candidates themselves in political campaigning and, secondly, to examine the impact of this phenomenon upon the media and, in turn, media engagement in such political tactics. The greater scope of this study evolves around the argument that Selfie Journalism, as a new species of participatory journalism, has penetrated the media in an effort to attract larger audiences.

The article will address both the theoretical and practical issues related to the design and implementation of SEO and also will cover previous research done on this topic. In order to give a better understanding of the importance of SEO in the current state of the Internet and in information search, basic knowledge of how search engines operate along with their recent updates will also be provided. The development of World Wide Web (Web 2.0) along with the growth of search engines over the last decade has brought significant changes in web content. In this context, we will see how SEO has evolved over the years since mid 90's when it first emerged. Nowadays, social media and social signals have increasingly become one of the many factors search engines take seriously into account, which is another issue that this article will address.

A lot of progress has been conducted during the last decades in Information and Communication Technologies, which is also reflected in social media. The proposed models take advantage of the latest media technologies for the augmentation of user-interaction and contribution experience in multiple levels. Features of the suggested agent and multi-agent approaches are discussed and elaborated through the prism of social computing, social media analytics and intelligence, resulting to a sophisticated communication mediator between users and social groups. In addition, enhanced user engagement and collaboration are considered in terms of rich media experience and augmented reality, semantic interaction services, intelligent content processing and management automation over interoperable multiplatform environments. Social media cooperation and integration is envisioned towards the realization of Web 3.0 and beyond, as the main chapter contribution.

This mainly happens because of the human need to produce more energy, so it can be used in services and in production. Obviously WWW is part of the problem since it is supported by a large number of data centers, which main function is to provide guaranteed reliable service, security and connectivity to the rest of the Internet via a high-capacity backbone. Data centers consume significant amounts of energy. According to News York Times data centers in the United States consume more than 1 billion watts of electricity each year. The aim of this book is to study possible methods that can be applied to media websites in order to reduce power consumption and to educate internet users on environmental issues. Some of the issues that the study addresses are: Whether the servers are powered by renewable sources of energy, the ecological graphic design of the websites, and the existence of energy saving mode, the prevention of printing articles, whether newspapers inform their readers about environmental issues and the interdependence or participation in actions related to environment protection.

Interactive media authoring and sharing technologies are currently being launched, bringing forward new ways of audiovisual (AV) content exchange. Web documentaries (web-docs) and hypermedia have appeared as a natural extension of filmed documentaries and digital TV, inheriting also some of their advantages. Narrative documentaries adopt AV mediated communication mechanisms that humans have been accustomed to be informed and communicate with each other, so that they are more informative and vivid compared to other documents (books, web-pages, multimedia, etc.). Thus, AV-documentaries and especially web-docs can be more easily distributed and attended from most ages and social groups (Dimoulas, Kalliris, Chatzara, Tsipas, & Papanikolaou, 2014a; Kotsakis, Kalliris & Dimoulas, 2012; Veglis, Dimoulas & Kalliris, 2014). Moreover, the continuous evolution of the computing power and the digital storage media, favor digital video production and distribution. This is also fuelled by the increased network speed, the efficiency of the contemporary compression algorithms and the continuous decrease of the corresponding costs (Kotsakis et al., 2012; Dimoulas, Kalliris & Veglis, 2014). High quality AV capturing equipment is currently available at low cost and size as part of smart phones and other mobile computing terminals with inherent networking capabilities, allowing easy AV-content production, contribution and sharing (Atzori, Delgado & Giusto, 2012; Dimoulas et al., 2014a; 2014b; Veglis et al. 2014). In this context, more and more users are involved in the AV production and consumption chain, so that creative experience and AV media culture are cultivated. Nevertheless, AV media related achievements are still far from the progress that has been made in textual information management during the outspread of social media and Web 2.0 services.

Interactive services have also been introduced into the AV production industry, aiming at augmenting human-machine interaction (HMI). AV content is enhanced in functional and informative level, further stimulating users to actively participate in arousing interactive scenarios. While the transition from Web 2.0 to Web 3.0 is ongoing, intelligent AV-content processing and management services are pursued, facilitating users’ participation on semantically enhanced hypermedia authoring and collaborative multichannel media publishing. Although hypermedia technologies are rapidly evolving, there are still open challenges regarding upcoming semantic web services (De Bra, Freyne, & Berkovsky, 2013; Dimoulas et al., 2014a; 2014b; Kanellopoulos, 2012; Monaghan, Handschuh, & O'Sullivan, 2011; Veglis et al. 2014). The current article examines current trends and future perspectives of AV hypermedia (AVH), considering all the forms of non-linear storytelling (web-docs, multichannel media publishing, etc.) and the associated hypermedia authoring counterparts. Background is presented providing basic definitions, involved technology, achieved progress and limitations. Recommendations and future research direction are then stated, aiming at serving a two-folded target. Firstly, to present new, user-friendly forms of collaborative creativity, hypermedia authoring and storytelling that current technology allows to be successfully deployed. Secondly, to suggest innovative adaptation mechanisms that can be utilized in both the AVH production and consumption ends, allowing for intelligent media management and augmented semantic interaction services to be launched. In this context, the importance of AVH toward the transition to the Web 3.0 era is revealed.

Cloud computing users have the flexibility to enjoy media content independently of time and space. Multimedia cloud computing encompasses technology, multimedia data and community contribution, offering augmented multimodal interaction and advanced processing services to the users. Mobile multimedia resources can now be accessed through the cloud practically at anytime and from anywhere, facing contemporary demands for information access and process, thus perfectly matching to the nature of news media. Such features are very favorable in online journalism and specifically in news reporting services. The current book chapter aims at presenting technological and application-oriented trends in cloud-based mobile news reporting both at journalists’ (news producers) and users’ (news consumers) sides. Future and emerging perspectives, such as ubiquitous and pervasive computing, incorporating context and location aware services in semantic interaction modes, are also described from the news-reporting point of view.

Its proponents argue that the Internet’s nature is characterized by a freedom of activity and thought. Due to the particular attributes of online news provided by technology and low publishing costs, thousands of people and organizations are allowed to self-publish and millions more have the opportunity to read alternative content outside the mainstream. However, there is increased evidence that large corporate portals and media trademarks are dominating online attention for news.
Greek people are not enthusiastic consumers of online news, firstly due to decreased interest in public affairs, and secondly due to low adoption rates of new technologies in their everyday lives. So what is the added value offered by greek online editions that would make a reluctant population to eventually turn to digital news? Drawing upon genre theory, the paper attempts to trace the evolution of the greek online newspaper. The websites of Ethnos, Ta Nea and Eleuferotypia are put into scrutiny in order to investigate: (a) how have greek newspaper websites evolved over time, and (b) how has the rationale of the online editions been shaped since their inception.

This is especially evident today, since data (and in many cases big data) are generated through various activities that relate to the production and also consumption of news. This paper attempts to highlight the importance of big data utilization in the media industry. Specifically, it discusses cases of big data exploitation, such as media content consumption and management, data journalism production, social content utilization, and participatory journalism applications. The study also examines the changes that big data has introduced in all stages of the journalism practice, from news production to news distribution, by utilizing the available tools. Finally, it discusses new developments that relate to semantic web (Web 3.0) technologies, which have already started to be adopted by media organizations around the world.

This cross-disciplinary research draws the attention of data journalism stakeholders to the mental operations (conscious choices and nonconscious mental processing) of a person who experiences storytelling with data. It is argued that data journalists can learn from the availability heuristic, the cognitive bias, and other concepts of cognitive science in an effort to become more attentive to the mental meFchanisms of their audience. Research from other disciplines, such as law (guilt determination) and economics, suggests that taking nonconscious decision-making seriously would be very productive for the field. Evidence suggests that a better understanding of the human brain's decision-making as well as of cognitive control may provide important insights for the data storytellers. This study is undertaken with an initial focus on the reasons why the audience acts upon emotional stories rather than data and statistics. We begin by arguing that data collection methods, measurement, and quantification may not be the only 'obscure' and difficult part to control for a data journalist, but after the cleaning, the analysis, and the visualization, the workings of the brain of the receptor, play a crucial role on what the individual will decide to do. The acts of journalism do not enter a tabula rasa, but rather a terra incognita. The research also examines the role of the language use by the data journalist; and whether language can overshadow data and consequently influence the reader's perception on the information from an article. The study uses theories from various disciplines (communication, psychology, neuroscience, and cognitive science) and gathers data by the use of qualitative research through interviews with cognitive scientists, neuroscientists, and psychologists.

Data visualisation, the method that allows communicating large amounts of data, can improve viewers" understanding of news and can increase interaction (Bradshaw 2010). The minimalistic theory of the "data-ink" ratio, which can design effective data visualisations, explains that ink should only be used to display the data. Data visualisations with right selection of visual channels can influence memory, attention, and news comprehension (Pan, 2010; Smilek, Dixon & Merikle, 2002). The purpose of this study is to explore if and how visual designers assess psychological principles in journalistic data visualisation. Data visualisations from two well-known organisations (the BBC and the Guardian) presenting COVID-19 information were collected. The analysis was effectuated based on a "decoding model" initiated by Munzner (2014) to identify their visual attributes. The findings concluded that media organisations consider and apply psychological metrics in the visual design process. Interesting colour differences between visualisations were identified and discussed. A limitation was that the sample of the study was small. Future research could include more data visualisations or could use interviews to understand better the way visual designers practice psychology.

The concept of different news consumption habits during a day has been well known for many decade... more The concept of different news consumption habits during a day has been well known for many decades in the broadcasting industry. News websites are also experiencing a drop in late afternoon traffic and a sharp drop in the evening hours. Furthermore, during the weekend, website traffic numbers appeared to be significantly different than the numbers during the weekdays. That resulted in the adoption of the concept of dayparting in the case of the internet. The existence of internet dayparts can have a significant impact on news websites since they can significantly determine their success. It is quite natural to assume that media organizations have adopted their publishing patterns to best satisfy the audience’s consumption patterns. This paper investigates those consumption patterns by conducting an extensive web survey among university students and particularly journalism and communication students that are expected to exhibit high consumption rates. The parameters being investigated include time, weekdays and weekends, and content categories. The study identified distinct periods that exhibit specific consumption patterns. The results appear to be to some degree in agreement with findings of previous studies that reported on publishing patterns, but significant differences have also been identified. Those results can provide valuable information for the implementation of successful content publishing strategies from the media organizations.

and profoundly impactful way. In this context, the technological developments of the past decades have fundamentally impacted the journalistic profession in more ways than one, opening up new possibilities and simultaneously creating a number of concerns for people working in the media industry. The changes that were brought about by the rise of automation and algorithmic technology can mainly be observed in four distinct fields of application within journalism: automated content production, data mining, news dissemination and content optimization. This article focuses on algorithmic journalism and aims to highlight the ways that algorithmic technology is being utilized within those fields, as well as pointing out the ways in which these developments have altered the way journalism is being exercised in the modern world. The study also discusses challenges related to these technologies that are yet to be addressed, as well as potential future implementations related to algorithmic journalism that has the capacity to improve on the foundation of automation in the news industry.

The huge power consumption of these online services has serious consequences regarding the environment. The web-sites, along with the web tools, need electrical power to operate. Thus, environmental problems such as global warming, air pollution, natural resource depletion, and acid rain are worsening. Consequently, this study researched five hundred news web-sites including well-known international news organizations in order to understand if they choose to cover environmental news, if they take action to protect the Earth's habitat by operating through renewable sources, by using the black colour in their graphic design or energy saving mode, and by organizing actions in favour of the environment. The findings of this original research revealed that almost none of the prominent news web-sites of the world seem to care about changing their web-sites in order to become environmentally friendly.

These patterns are close related with dayparts, which are defined as sequential time blocks on comparable days during which the audience size is homogeneous, as is the group depiction using the specific medium. During the first decade of the World Wide Web, Internet media strategy was focused on total web reach, demographics and affinity of content without particular attention to how the nature of the audience changes by time of day. This paper studies the variation of publishing patterns of the top 22 Greek media websites. More than 550 thousand articles were indexed in a period of four and a half months. The study identified distinct WWW time periods that exhibit specific publishing characteristics. Specifically, different categories of news articles present different publishing patterns during weekdays and weekends. The results appear to be in agreement with findings of previous studies.

This occurs because most of the content today is published in an unregulated way, and they have to navigate a network of unstructured interconnected forms of data. The lack of an efficient infrastructure in which they could easily discover, acquire, and analyze the information needed limits the exploitation prospects. The solution to this problem can be given by the advancement of Web 3.0 or Semantic Web (SW).

This Special Issue is soliciting theoretical and case study contributions, discussing and treating challenges, state-of-the-art, and solutions on Web 3.0 application in the media sector, including but not limited to:

- Theory of Web 3.0 in relation with media organizations,
- Application of Web 3.0 in the media sector,
- Journalism 3.0 practices and procedures,
- Semantically enhanced news validation & management,
etc.

As a result, the workflows and methods of different business sectors are undergoing constant change. The news industry and journalism are heavily affected by these changes. New technological means for practicing journalism and producing news items are being incorporated in media workflows, challenging well established journalistic norms and practices. The perpetual technological evolution of the web creates a wide range of opportunities. For this reason, both technology companies and media organizations have begun to experiment with semantic web technologies. Our focus in this paper was to discover and define the ways that semantic technologies can contribute to the technological upgrade of everyday journalism. From this perspective, we introduced the term 'semantic journalism' and attempted to investigate the transition of journalism to a semantic-oriented technological framework.

This study shows the usability of a news chatbot during a crisis situation, employing the 2020 COVID-19 pandemic as a case study. The basic targets of the research are to design and implement a chatbot in a news media platform with a twofold aim in regard to evaluation: first, the technical effort of creating a functional and robust news chatbot in a crisis situation both from the AI perspective and interoperability with other platforms, which constitutes the novelty of the approach; and second, users' perception regarding the appropriation of this news chatbot as an alternative means of accessing existing information during a crisis situation. The chatbot designed was evaluated in terms of effectively fulfilling the social responsibility function of crisis reporting, to deliver timely and accurate information on the COVID-19 pandemic to a wide audience. In this light, this study shows the advantages of implementing chatbots in news platforms during a crisis situation, when the audience's needs for timely and accurate information rapidly increase.

In the evolving news media landscape, the proliferation of user-generated con-tent in online news outlets and social media platforms has triggered changes in traditional processes and relationships. However, the coexistence of professional and amateur content raises a wide range of matters. Misinformation is one of the main problems faced by media organizations during the exploitation of huge amounts of data. In order to ensure the quality of the content, journalists use con-trol methods and perform fact-checking not only on their own, but also by engag-ing users. By offering an examination of key issues arising from UGC research, this article seeks to focus on the application of participatory practices in fact-checking. In addition to more traditional methods, the web-based platform of Tru-ly Media, which supports collaborative verification, is used as a case-study.

Media production and consumption have been altered considerably and traditional concepts, such as gatekeeping, have been under discussion. Many news organisations include in their websites tools and applications that allow users to be active consumers or even co-producers of journalistic content, by liking, sharing, commenting and submitting material. At the same time, large amounts of user-generated content are uploaded every day on social media platforms. Subsequently, media organisations must deal with continually available information which requires management, classification and evaluation not only to keep high journalistic standards, but also to avoid problems. The latter category can include grammar mistakes, fake or misleading information and hate speech. All the above-mentioned parameters highlight the obvious need for platforms that can support journalism manage practice. Such a platform should utilise semantic technologies, which can support organised collection and moderation of content in an effective way and in short time. This study discusses the design and the implementation of a participatory journalism management platform.

A thorough understanding of how to include these practices in media education and also to measure their impact on journalism students’ daily practice is a major challenge. This paper aims to examine the effectiveness of fact checking and verification training through a qualitative study based on two focus groups of journalism students that have been trained in implementing such techniques in Greece and Cyprus. Our intention is to examine the extent to which these groups can implement and evaluate such tools in their daily practices. As such, the method used is focus group interviews to assess attitudes toward fact checking techniques. Through our analysis we aim to document several important challenges in introducing these courses. To this end, this study presents the most in-depth examination of journalism students’ attitudes towards fact checking to date and of its effects on students’ factual knowledge and implementation. Overall, this paper reports on the lessons learned by introducing fact checking and verification in teaching journalism curricula in an era beyond digitalization.

The diffusion of user-generated content both in news websites and on social media platforms has led media organizations to employ participatory formats that allow the audience to actively consume or co-produce content. As a result, journalists are often challenged by a vast amount of-vulnerable to problems-content that has to be handled in tandem with their other daily tasks. This paper focuses on the development of participatory journalism practices in Greek media. Specifically, in order to examine opportunities for users' involvement in news organizations, a comparative quantitative study in all national daily political and financial online newspapers in Greece was conducted in 2014 and 2018. For this purpose, both the integration of participatory tools and the use of quality assurance methods in the relative websites were investigated. The findings indicate a rather reluctant attitude towards productive ways of engagement. Participation takes place through a limited number of tools and user-generated content is accepted only when filtered.

Traditional procedures and concepts such as gatekeeping have been under discussion. News organizations redesign their websites in order to adopt tools and applications that make it possible for users to be active consumers or even co-producers of journalistic content, by liking, sharing, commenting and submitting material. At the same time, huge amounts of user-generated content are uploaded every minuteon social media platforms. Subsequently, professionals have to deal with continually available information which requires management, classification and evaluation in order to keep high journalistic standards and to avoid problems, varying from plain grammar mistakes to serious situations of fake news, hostility or hate speech. Thus, there is the obvious need for a new model of managing participatory journalism, based on semantic technologies, which will support organized collection and moderation of content in an effective way and in short time. The main objective of this paper is to define the requirements and describe the characteristics that the model should have. For this purpose, two online surveys of journalists and users were conducted in Greece, in order to gain some insights concerning the development of the model. The paper presents the key findings from the surveys and identifies the views, the preferences and the experiences as expressed by the respondents, which lead to the tendency towards a collaborative, semantic-oriented way of submitting and receiving user-generated content.

While news organizations rely on marketing and exposure metrics to program their cross-media presence, at the same time an urgent need for credible and quality journalistic services constantly rises. A promising solution, proposed in this paper, would be to reshape Search Engine Optimization (SEO) practices and measures, aiming at expediting self-verification and authentication processes. Hence, informing sources would have the option to voluntary ingest credibility metadata of their content and stories, allowing end-users to easily fact-check the delivered messages.

Concurrently, journalists and media professionals need to be aware and possess a new set of skills connected to web technologies, as well as respond to new reading tendencies and information consumption habits. A number of studies have shown that search engines are an important source of the traffic to news websites around the world, identifying the significance of high rankings in search results. Journalists are writing to be read, and that means ensuring that their news content is found, also, by search engines. In this context, this paper represents an exploratory study on the use of search engine optimization (SEO) in news websites. A series of semi-structured, in-depth interviews with professionals at four Greek media organizations uncover trends and address issues, such as how SEO policy is operationalized and applied inside newsrooms, which are the most common optimization practices, as well as the impact on journalism and news content. Today, news publishers have embraced the use of SEO practices, something that is clear also from this study. However, the absence of a distinct SEO culture was evident in newsrooms under study. Finally, according to results, SEO strategy seems to depend on factors, such as ownership and market orientation, editorial priorities or organizational structures.

Likewise, the objective of this study is to present the design and the development of an educational web application for learning the necessary steps towards the detection of bogus content, according to the fact-checking procedures. The game presents news articles, which have to be characterized as fake or real by the players. During the effort to reach the correct decision, the players can use tools and practices for identifying relevant information regarding the clues, which frame a news story (title, date, creator, source, containing images). After presenting the progress of interface design and development, this paper reports the results of a randomized online field study (n = 111), which provides some preliminary evidence. Specifically, it is validated that the game can raise awareness, teach about authentication tools, and highlight the importance of patterns that include evidence regarding the authenticity of articles. Additionally, thorough discussion was conducted within a media class (n = 35) to receive useful feedback/evaluation about the offered utilities and their usability. The findings suggest that educational games may be a promising vehicle to inoculate the public against misinformation.

They experience an increase in the level of concentration but also an increase in the number of news media companies. Many of these new entrants in the broadcast industry operate without a license. This chapter also shows that the news media industry was hit very hard during the recent economic crisis. Many companies had to close down and the scarcity of funding of activities increased. Many media companies focused on the reduction of costs instead of improving quality or stimulating innovation. Although, the Greek government had a strong presence and influence on the media landscape, it did not develop a regulatory framework. Nowadays, despite the existence of rules supporting the development of large media companies, the news media markets are still experiencing fierce competition, are highly concentrated and offering low-level of content quality and technological innovations. The Greek media are following approaches and methods from abroad even without the necessary adaptations or a proper plan for implementation and modifications.

More specifically, progress in the last two decades led to the end-to-end digitalization of the media industry, resulting in a rapidly evolving media landscape. In addition to news digitization, User-Generated Content (UGC) is dominant in this new environment, also fueled by Social Media, which has become commonplace for news publishing, propagation, consumption, and interactions. However, the exponential increase in produced and distributed content, with the multiplied growth in the number of plenary individuals involved in the processes, created urgent needs and challenges that need careful treatment. Hence, intelligent processing and automation incorporated into the Semantic Web vision, also known as Web 3.0, aim at providing sophisticated data documentation, retrieval, and management solutions to meet the demands of the new digital world. Specifically, fo...

Within this context, chatbots started to infiltrate the media sphere and provide news organizations with new and innovative ways to create and share their content, with an even larger emphasis on back-and-forth communication and news reporting personalization. The present research highlights two important factors that can determine the efficient integration of chatbots in professional journalism: the feasibility of chatbot programming by journalists without a background in computer science using coding-free platforms and the usability of the created chatbot agents for news reporting to the audience. This paper aims to review some of the most popular, coding-free chatbot creation platforms that are available to journalists today. To that end, a three-phase evaluation framework is introduced. First off, the interactivity features th...

In this context, technology has become an integral part of every business industry. The development of Information and Communication Technologies (ICTs) along with the progress of internet has had significant impact on the journalistic field. However, journalism profession has always been considered to be closely related to technology. Digital Journalism has been growing steadily during the last years introducing new trends and practices in journalism education. This has led to an increasingly demand for trained journalists concerning new skills and standards. Nowadays, the journalist is expected to have the ability to exploit a variety of tools and services in order to deal successfully with the changing work demands. While traditional work skills remain essential elements of the journalistic education, the challenge is to combine these with the needs of the new digital information age. Journalism education can play a significant role in the changing environment of media industry. The present study focuses on the general and practical ICT knowledge of the 1st year undergraduate students in the School of Journalism & Mass Media Communication in Greece during the period 2003 - 2014. More specifically, the purpose was mainly to assess, over time, the progress of their knowledge and skills as well as to see their educational and training needs as future journalists. In summary, the findings presented in this paper demonstrate a significant improvement in knowledge of journalism students regarding ICTs. Finally, through students' opinion the paper discusses the necessity of ICTs in the journalism education as well as in journalism profession and work processes.

However, the structure of a significant amount of news websites seems to have been changing, often deviating from trends of past years or even setting their own marketing direction. Based on seven hypotheses related with online marketing characteristics, the researchers gathered data from articles posted on Greek news websites that reported three major events. After visiting the websites for a second time in order to compare the data, they calculated our results. These results show a clearer picture of how the situation currently is for the top twenty Greek news websites according to Αlexa.com. This paper also highlights newer trends in online news reporting, such as the elimination of the “like” button in favour of the shares, and also makes suggestions for further research.

The development of online journalism has affected the processes of journalistic work, creating at the same time new techniques and practices. On the internet, search engines still drive a great amount of traffic to news websites. For that reason, factors such as visibility and high ranking on search engines’ results pages remain crucially important for media organizations. Nowadays, journalists or Web editors should be able to write and create appropriate content for the Web. This paper discusses in detail the impact of Search Engine Optimization (SEO) on digital journalism. Through a quantitative analysis, a survey concerning Greek media websites is presented. The aim was twofold: on the one hand, to find out to what extent the use of SEO affects the traffic of a media website whilst, on the other hand, to discover to what degree media professionals in Greece utilize the possibilities given through search engines in order to increase traffic. Finally, a number of SEO elements and practices often used in news content are noted.

The main aim of the work is to identify and describe the mechanisms that the attributes of source content (and its encoding properties) influence the learning process and the involved emotional aspects in terms of Quality of Experience and Learning (QoE & QoL) parameters. Subjective sentiment analysis tests are implemented along with QoE /QoL evaluation parameters and perceptually-adapted QoE metrics in real-world mediated learning scenarios. The obtained knowledge would be very helpful while preparing and designing audiovisual mediated tutoring and/or broadcasted distance learning courses, but also in many other fields associated with multimedia quality of experience and sentiment analysis.
