Schema markup is code that enables search engines to understand and categorize web page content. Google uses schema markup to show rich results, which are more engaging for searchers than regular search results.

Why is schema markup important for search engine optimization (SEO)?

Schema markup is important for SEO because it benefits both search engines and users. Structured data gives search engines clear instructions about your page’s content, helping them understand and index your pages more accurately. It also enables Google to display rich results — like images or breadcrumbs — that make your listing stand out in search.

Here’s why schema markup matters:

• Helps search engines understand your content by providing explicit, structured information.
• Improves indexing accuracy, ensuring your pages are categorized and interpreted correctly.
• Enables rich results in SERPs, such as images and breadcrumbs, which enhance visibility.
• Creates a more engaging search experience for users by offering additional details upfront.
• Supports higher click-through rates by showing searchers what they can expect before visiting your page.

Schema markup ultimately enhances both discoverability and user engagement, making it a valuable part of any SEO strategy.

“Schema markup is a powerful tool for keeping up with the evolving world of SEO. It gives search engines and AI systems clear context about your page’s content, helping your site not only rank higher in traditional search results but also get recognized and cited in emerging AI-powered platforms.”

Local business

The local business rich result shows up in the Google knowledge panel, displaying a local service business’s details such as:

• Address
• Business hours
• Phone numbers
• Link to make a reservation or book an appointment
• Ratings
• Reviews
• Information provided by the local business

How to add schema markup for your pages

Here’s your step-by-step guide to generating schema markup for your pages:

1. Visit Google’s Structured Data Markup Helper
2. Select a page from your site that you’ll mark up
3. Mark up the different elements on your page
4. Generate the HTML code
5. Add your schema markup code to your site
6. Test your schema markup

1. Visit Google’s Structured Data Markup Helper

The Structured Data Markup Helper is a tool that helps you create markup elements on your page.

2. Select a page from your site that you’ll mark up

Once you’ve selected a page on your site, tick the radio button of the appropriate data type that you’ll mark on the page on the Structured Data Markup Helper. In our example, we chose the Product markup for a product page.

Then, paste either the page’s URL you want to mark up or your HTML code.

3. Mark up the different elements on your page

If you add your URL, you can start marking up your page by selecting text or images. In the example below, the brand name of the product is selected. On the right side, your recorded tags will appear.

Want to add other tags? You can click the Add Missing Tags button in the lower right-hand corner to add tags manually.

While a structured data best practice is to add tags only found on the page, you can still add tags like the page URL.

4. Generate the HTML code

Once you’re done tagging, click the Create HTML red button at the top right corner. You’ll be given the option to download the code in either JSON-LD or microdata. It’s best practice to use JSON-LD.

5. Add your schema markup code to your site

Log onto your content management system (CMS) and add your code. If you put your HTML instead of URL in the Structured Data Markup Helper in step #2, copy and paste the HTML file, and paste it to your CMS or source code.

6. Test your schema markup

Use Google’s Structured Data Testing Tool to test your markup for any errors. Enter either your URL with the schema markup or the code snippet. The tool will show you the errors and warnings it detects.

You can directly edit the code on the Structured Data Testing Tool to fix any errors. Click the Run Test button to check your changes.

Schema markup best practices

Now that you know how to add schema markup on your pages, here are best practices to take note of to maximize its benefits:

1. Use the JSON-LD format. While Google supports JSON-LD, Microdata, and RDFa formats, JSON-LD Is the easiest format to maintain.
2. Find the most common and suited schema markup for your business. Improve your pages’ click-through rates by using schema markup that will help your target audience and address their search intent.
3. Mark up what is on the page. Provide your target audience with the content they expect when they click on the rich result that features your page. For example, your product page’s structured data has the pricing and special offer information. Ensure that the product page has these details, too.
4. Always test your structured data. Ensure your page has no schema markup issues by always testing it.

Schema SEO and AI visibility

Structured data doesn’t just help your pages appear as rich results — it also helps your brand get cited in AI-generated answers. In the era of Schema SEO, schema markup gives AI systems like ChatGPT, Gemini, and Perplexity the context they need to understand, trust, and attribute your content accurately.

By adding schema types like Article, FAQ, HowTo, Product, and Organization, you make it easier for AI models to interpret your content and mention your brand in conversational results. These AI citations boost visibility, build brand authority, and position your website as a trusted source in the age of AI-powered search.

“Schema markup is a real asset in helping to navigate and keep up with this new age of SEO! Schema provides lots of information to crawlers and search engines about the topic of your page and the content that’s on it! Providing this information is essential to help you not only increase organic search rankings, but also get pulled and cited by AI tools like ChatGPT and AI Overviews on Google to boost your online visibility and impressions!”
