8 Bad SEO Practices to Avoid & What to Do Instead (original) (raw)

What Are Bad SEO Practices?

Bad SEO practices are those that violate search engine guidelines or negatively affect the user experience. These practices undermine the primary goal of search engines and AI tools: to help users find helpful, relevant, and trustworthy information.

Some bad SEO practices are unintentional, often stemming from outdated tactics—like keyword stuffing. Although frequent keyword repetition once helped sites appear higher in Google, it reduces readability and can lower visibility.

Here’s an example of keyword stuffing:

Plus, repeatedly using the same query can prevent you from gaining visibility in AI platforms like ChatGPT. Those tools use a query fan-out process that considers the multitude of ways people speak about a given topic when seeking relevant sources.

Other bad SEO practices are intentional and manipulative, such as using private blog networks (PBNs), cloaking, or buying spammy backlinks. These methods may deliver short-term results but typically result in penalties from search engines.

Consequences of Bad SEO

Here’s what can happen if you fall into adverse SEO habits:

8 Bad SEO Practices (with Examples)

We surveyed 58 SEOs and content marketers on LinkedIn about the most harmful SEO practices. Below are the results, ordered from most to least problematic.

Bad SEO Practice % Saying It’s Most Problematic
Creating unhelpful content that lacks expertise 29.3%
Over-optimizing for search 24.1%
Using private blog networks 12.1%
Delivering a poor user experience 15.5%
Manipulating search engines with cloaking 6.9%
Publishing generic, AI-generated content 6.9%
Having duplicate content 3.4%
Relying on reputation abuse 1.7%

1. Creating Unhelpful Content That Lacks Expertise

Content that doesn’t provide real value or expertise often struggles to rank highly in search engines. And it’s less likely to show in AI search as well.

From our survey, 29.3% of the respondents identified this as the most problematic bad SEO practice.

Google prioritizes content that’s helpful, trustworthy, and authored by experts. That also matters for AI systems when you consider they often use Google results.

So, if you’re writing about fitness tips and simply rehash information from existing articles (like “do cardio” and “lift weights”) without offering unique insights, search engines, AI tools, and users will likely see your page as low-value.

When content is written more for search engines and AI systems than people, it often performs poorly by all measures. And 24.1% of our survey participants flagged over-optimization as a significant concern.

Over-optimization occurs when content is so focused on showing up in search that it becomes unnatural for readers. This can happen through excessive keyword use, awkward anchor text, or unhelpful and repeated internal links.

Over-optimized content often comes off as clunky, robotic, or spammy. It disrupts the reading flow, hurts user experience, and may even trigger Google penalties.

3. Using Private Blog Networks

A private blog network (PBN) is a network of websites built to link to your site to improve its search performance.

SEOs build PBNs by either setting up new sites or purchasing high-authority domains. These sites then link to your site to increase its authority.

Though PBNs can sometimes improve performance, using them is high risk.

If Google catches you trying to manipulate performance in this way, your site could be penalized or even removed from search results. Of our survey participants, 12.1% highlighted this tactic as problematic.

Edward White, Founding Growth Lead at Brightwave, faced this issue firsthand in a previous role when his team decided to test out a third-party SEO service:

“Within weeks, I noticed a suspiciously fast spike in referring domains. A deeper audit revealed the sites were part of a disguised PBN. We cut ties immediately and submitted a disavow file. Fortunately, the domains hadn’t yet been indexed, so we avoided penalties.

As a result, Edward and his team rethought how to evaluate link sources and made sure to vet every backlink strategy.

“We also prioritized digital PR over synthetic backlinking. After the change, our organic traffic grew steadily with lower volatility.”

What to Do Instead

Focus on building authority in a legitimate and sustainable way:

4. Delivering a Poor User Experience

Providing a poor user experience (UX) can mean long load times, mobile issues, autoplay videos, intrusive pop-ups, aggressive CTAs, sticky widgets, and more.

For instance, say a user wants to read your blog post but is confronted by a full-screen pop-up, an autoplay video, and a “tap to reveal” block. Frustrated, they click out of the page.

Almost 16% of our survey respondents identified poor UX as a major issue.

Survey respondent Becky Cockcroft, a Freelance SEO Manager, offers a useful approach for knowing whether you’re providing good UX:

"Imagine if you were the user. The real goal is to create a seamless and enjoyable experience for them—because that’s what truly drives engagement and satisfaction."

Google considers user engagement signals when determining where pages should show in results, which means those signals can also impact AI visibility. If users struggle to navigate your site or get bombarded with distractions, it’s likely to negatively impact your performance.

What to Do Instead

Make your content easy to read and navigate by:

Use Semrush’s Site Audit tool to spot UX issues you can address to maintain your search visibility.

5. Manipulating Search Engines with Cloaking

Cloaking is a tactic that purposely shows different content to search engines versus users. It violates Google’s guidelines and is a quick way to get penalized or even deindexed.

Cloaking is showing Google one kind of page but redirecting users to another, different kind of page.

An example of cloaking is when a site shows Google an optimized page about training dogs. But when a user clicks the link, they’re redirected to a sales page for dog treats.

Nearly 7% of survey participants identified cloaking as a significant SEO mistake.

What to Do Instead

Avoid cloaking and instead:

6. Publishing Generic, AI-Generated Content

AI-generated content that lacks originality and depth can negatively affect your performance in search engines and AI tools.

Google’s helpful content update aims to prioritize high-quality, user-focused content. Low-value AI content can result in penalties and reduced visibility.

Close to 7% of our survey participants say publishing generic, AI-generated content is the most problematic bad SEO practice.

What to Do Instead

Use AI to support your content creation—not to replace it. Here’s how:

Use Semrush’s Content Toolkit to create high-quality content at scale. The toolkit guides you through the stages of content production, from topic ideation to publication.

7. Duplicate Content

Duplicate content pages that have identical or nearly identical content can lead to lower or even no search visibility for that content.

According to our survey, 3.4% of survey respondents identified duplicate content as a notable SEO concern.

Duplicate content can even occur without you realizing it. For instance:

What To Do Instead:

There are several ways to prevent or address duplicate content:

Once you’ve configured your project, head to the “Issues” tab and search for “duplicate content.”

8. Reputation Abuse

Reputation abuse involves leveraging another website’s authority to manipulate rankings.

Close to 2% of survey respondents flagged regulation abuse as the most concerning bad SEO practice.

Forbes Advisor was widely criticized for engaging in reputation abuse by capitalizing on the main domain’s authority to get high search visibility for pages covering topics outside their areas of expertise. And Forbes Advisor saw a sharp decrease in organic traffic following Google’s reputation abuse policy update at the end of 2024.
