What is Schema in SEO?

If you’re just getting started with technical SEO, schema can look and sound incredibly confusing. Whether you’re looking to implement local business schema to help more local users find your services or just trying to understand more about what schema is and why it’s important, you’re in the right place. In this blog, we’ll go over everything you need to know about schema, including what it is, why it’s important for SEO, how to create and implement it, and the most important types. 

Key Takeaways

Here’s a quick introduction to schema markup and why it’s so important to SEO:

What is Schema Markup?

Schema markup, also known as structured data, is code you can add to your website to help search engines read and understand your content. This code helps search engines display your content in a rich format. 

In the example above, Google has displayed an image, author, star rating, review count, cooking time and recipe ingredients in a dedicated Recipes section. For the above search results, this Recipes section appears before the rest of the search results, allowing you to gain a competitive edge over your competitors. 

Although search engines are very powerful tools, they don’t have the same visual and linguistic understanding of content as humans. This means they require additional information to read, identify and categorise content. Although a human might look at a list of ingredients and quantities and intuitively understand that they’re looking at a recipe, search engines lack this intuitive understanding. 

Adding recipe schema and including recipe ingredients (pictured above) helps search engines understand that a particular webpage is a recipe and should be shown for relevant recipe searches. Without schema, search engines would find it much more difficult to understand the meaning of content. 

Schema can be applied to pages through encodings, such as RDFa, Microdata, and JSON-LD. All three languages are supported by Google, however, JSON-LD is preferred as it is the easiest to understand. 

What is Schema.org?

Schema.org is an independent, community-driven project that helps people add structured data to their web pages. It provides a collection of schemas that are used to apply structured data markup to different types of content, such as recipe schema, product schema and organisation schema. Since 2011, Schema.org has collaborated with search engines, such as Google, Yahoo, Bing and Yandex, to create, maintain and promote schemas. 

Why is Schema Important in SEO?

Although schema is not a ranking, that does not mean that it is not important for SEO. Here are five of the main reasons why you should consider adding relevant schema to your website. 

Makes Your Pages Eligible to Appear in Rich Results 

Although it is technically possible for Google to display rich results based on its own understanding of content, adding schema helps Google understand your content much easier and therefore increases the likelihood of your page appearing in rich results. 

There is a wide range of rich results or snippets that can be achieved by adding relevant structured data:

Below you can see an example of how the BBC appears as an organisation snippet, including founding date, founders, headquarters, number of employees and its predecessor. 

Check out our blog, ‘How Do You Appear in Rich Results?’, for more information. 

Improved Click-Through Rates

Adding schema to your website means you’re more likely to appear in rich results, which means more people are likely to notice and click on your page. Rich results are more engaging and include additional information, such as a review rating, that can entice users to click on your page above your competitors. This can enhance your click-through rate and bring more traffic to your webpage. 

Helps Search Engines Understand Your Content Better

Schema markup is essential in helping search engines, like Google, better understand the meaning, context and content of your pages. Sometimes search engines have a hard time understanding the exact meaning of words, especially when they have multiple meanings. Take a look at this example from Schema.org:

“Most webmasters are familiar with HTML tags on their pages. Usually, HTML tags tell the browser how to display the information included in the tag. For example, <h1>Avatar</h1> tells the browser to display the text string “Avatar” in a heading 1 format.

However, the HTML tag doesn’t give any information about what that text string means—“Avatar” could refer to the hugely successful 3D movie, or it could refer to a type of profile picture—and this can make it more difficult for search engines to intelligently display relevant content to a user.”

Ensuring that search engines fully understand the meaning of your content can help your pages be shown for more relevant search queries, which can lead to more rankings and more traffic. 

Aligns Your Website With How AI Algorithms Understand Content

Schema can also be used to build a knowledge graph of entities and topics. This helps to align your website with how AI algorithms categorise content and helps your site appear in AI Overviews, first launched in the US in May 2024. 

The following quote from Google helps explain why schema is a useful tool for helping your site ranking in AI Overviews:

“You can help us by providing explicit clues about the meaning of a page to Google by including structured data on the page.

For example, on a recipe page, what are the ingredients, the cooking time and temperature, the calories, and so on.”

Allows You To Gain a Competitive Edge Over Your Competitors

Although schema has been around since 2011, many sites still aren’t utilising schema markup to its full capabilities and many aren’t using it at all. Properly marking up your site is an effective way to get ahead of your competitors and make your website stand out in the search results. 

To learn more about the importance of schema for SEO, take a look at our blog, ‘Is Structured Data a Google Ranking Factor?’.

How to Create Structured Data?

Schema markup can be created manually and this might be a good option if you only need to implement basic schema, such as organisation schema. However, for more complex types of schema, you can use online tools, such as Google’s Structured Data Markup Helper or the Merkle Schema Markup Generator.

You can also use AI platforms, such as chat GPT, to provide you with a template for a particular type of schema. Then, you can fill in the gaps with your own information. 

Whatever method you use, you must validate your schema to ensure it’s correct. Copy the code and run it through two different structured data testing tools. Google recommends using their Rich Results Test and the Schema Markup Validator from Schema.org. 

There are also a range of plugins that you can install to dynamically generate structured data. This includes Yoast SEO, Rank Math or All In One SEO for WordPress.  Implementing schema through these tools will ensure your markup stays up to date, which can be particularly useful for large eCommerce sites. 

How To Add Schema To a Website

Once you’ve created your structured data, either manually or through an online tool, you’ll have some code that you can add to your website. There are a few different ways that you can add this:

Add Schema Manually 

JSON-LD schema markup should be implemented directly in the page source code. It can be added within <script> tags in the <head> of your page. 

If you’re adding schema markup that needs to be on all pages, like breadcrumb schema, you’ll need to add it in a place in your CMS that allows sitewide scripts. Look for settings that allow you to add scripts to your header or footer.

For a lot of schema markup, you’ll only need to add it to one page. How you approach this will depend on your CMS system. In many cases, it should be possible to use a field to add scripts to an individual page’s header or footer. 

Add Schema Using Google Tag Manager

If you’re looking to add schema to your website, using Google Tag Manager is the simplest way, especially if you already have it set up! Here’s the process you’ll need to follow:

1. Create a New Custom HTML Tag.

Name it according to what the schema is, for example, ‘Organisation Schema Markup’.

2. Paste JSON-LD Schema Markup

Paste the schema markup you have created manually or through an online tool (make sure you’ve validated it first) into the text box. 

3. Click Save and Add Your Page View Trigger

You will need to create a Page View trigger for your tag to fire on. Click the plus icon on the right-hand side and choose Add Trigger. Name the trigger based on which page or pages you want your structured data on. I’ve called mine Home Page View as I will be adding organisation schema which should be placed on the home page or about us page. Choose Page View for your Trigger Type

4. Configure Your Page View Trigger

Choose All Page Views if you want your structured data to appear on all pages or Some Page Views if you only want it to appear on certain pages. You can then choose ‘Page URL’ and select ‘equals’ or ‘contains’ depending on which pages you want your structured data on. I’ve selected ‘equals’ and put the URL of my website’s home page, as I only want my organisation schema on this page. Click Save.

5. Connect Your Page View Trigger to Your Tag

Select the ‘Organisation Schema Markup’ you created in step 1 and open it. Choose the ‘Page View’ trigger you just created to ensure your tag fires on the desired page or pages. Save your tag.

6. Publish Your Google Tag Manager container

Click Submit and then Publish. You can add a version name and description of what you’ve added. 

7. Test Your Markup 

You should use the Rich Results Test and the Schema Markup Validator to check your schema is working properly, by entering the URL of the page with the newly added structured data on. For my example, the organisation schema is detected by the Rich Results test and shows on the Schema Markup Validator with zero warnings or errors. 

Add Schema Using a Plugin

As I mentioned earlier, you can also create and implement schema dynamically using a plugin. 

What Are the Main Types of Schemas?

There are currently 811 types of schema, according to Schema.org (as of February 2025). However, most of these are very specific and will rarely need to be implemented. Here’s an overview of the most common types of schema:

We’ll go into these in a bit more detail below. 

What is Local Business Schema?

Local Business Schema is a structured data markup that provides search engines with additional information about a local business. This includes:

As a general rule, you should implement Local Business schema on your homepage. If you have more than one location, we have some advice about the best practice for implementing Local Business schema in our blog, ‘Should You Add Local Business Schema on Every Page?’.

What is Organisation Schema?

Organisation Schema is fairly similar to Local Business Schema, but it can be used for any type of organisation, company or business. It provides search engines with detailed information, including:

Organisation schema is typically implemented on the home page or About Us page. 

What is Recipe Schema?

Recipe Schema allows you to provide detailed information about a recipe on your website in a format that search engines can easily understand. Implementing recipe schema allows your recipe to appear in a dedicated Recipes section in the search results. Recipe schema can include:

Recipe schema should be added to an individual page and tailored to the specific recipe on that page. 

What is Product Schema?

Product Schema is a type of structured data markup that provides detailed information about a product being sold on a website. Implementing product schema helps search engines better understand products and display them in rich snippets in search results. Here is some information that can be included in product schema:

Specific product schema should be added to individual product pages, but aggregated product information can also be added to category pages using Item List structured data. Here’s a simplified example of what this might look like:

<script type="application/ld+json">

{

  "@context": "https://schema.org",

  "@type": "ItemList",

  "name": "White Trainers",

  "url": "https://www.example.com/category/white-trainers",

  "itemListElement": [

    {

      "@type": "ListItem",

      "position": 1,

      "item": {

        "@type": "Product",

        "name": "Classic White Sneakers",

        "image": "https://www.example.com/images/classic-white-sneakers.jpg",

        "description": "Comfortable and stylish classic white sneakers for everyday wear.",

        "url": "https://www.example.com/product/classic-white-sneakers",

        "offers": {

          "@type": "Offer",

          "priceCurrency": "USD",

          "price": "49.99",

          "availability": "InStock",

          "url": "https://www.example.com/product/classic-white-sneakers"

        }

      }

    },

    {

      "@type": "ListItem",

      "position": 2,

      "item": {

        "@type": "Product",

        "name": "White Running Shoes",

        "image": "https://www.example.com/images/white-running-shoes.jpg",

        "description": "Lightweight and durable white running shoes for athletes.",

        "url": "https://www.example.com/product/white-running-shoes",

        "offers": {

          "@type": "Offer",

          "priceCurrency": "USD",

          "price": "69.99",

          "availability": "InStock",

          "url": "https://www.example.com/product/white-running-shoes"

        }

      }

    }

  ]

}

</script>

What is Breadcrumb Schema?

Breadcrumb Schema is structured data that helps search engines understand the hierarchy and navigation of a website. It does this by defining the path that a user must follow to get to a specific page. Breadcrumb schema allows Google to display breadcrumb navigation in search results. In the example below, this looks like www.bbc.com > news > world. 

The key elements that need to be implemented are::

Here’s a simplified  example of what breadcrumb schema might look like for the above example:

<script type="application/ld+json">

{

  "@context": "https://schema.org",

  "@type": "BreadcrumbList",

  "itemListElement": [

    {

      "@type": "ListItem",

      "position": 1,

      "item": {

        "@type": "WebPage",

        "name": "Home",

        "url": "https://www.bbc.com/"

      }

    },

    {

      "@type": "ListItem",

      "position": 2,

      "item": {

        "@type": "WebPage",

        "name": "News",

        "url": "https://www.bbc.com/news"

      }

    },

    {

      "@type": "ListItem",

      "position": 3,

      "item": {

        "@type": "WebPage",

        "name": "World",

        "url": "https://www.bbc.com/news/world"

      }

    }

  ]

}

</script>

Breadcrumb schema should be added to any page where you have breadcrumb navigation visible to the user (in the header or at the top of the page). Each page will need its own breadcrumb schema to reflect its position in the website hierarchy. 

What is Blog Schema?

Blog schema provides additional information about blog posts or articles on a website to help search engines understand them better. Implementing blog schema communicates that you’re offering helpful informative content, helping search engines serve your blog post for relevant queries. Blog schema should be added to individual blog posts. 

Here’s an overview of what’s typically included in blog schema:

What is Review Schema?

Review Schema is used to mark up reviews on a website to help search engines understand ratings and reviews of products and services. When implemented correctly, it can help rich snippets appear in search results. Review schema should be added to all pages with reviews. Here’s what is typically included in review schema:

What is Person Schema?

Person Schema is used to mark up information about a person and includes details such as:

Person schema should be added to individual ‘About Me’ or ‘Team Member’ pages, or author pages for blog posts. 

What is Video Schema?

Video Schema is used to describe video content on a website to allow search engines to understand it better and make it eligible to appear in rich results, such as video snippets. Implementing it can help improve video visibility and help videos rank higher in search results. Here’s the information that’s typically included in video schema:

Video schema should be added to pages with important or informative video content, such as tutorials, how-to videos or interviews. 

What is FAQ Schema?

FAQ Schema helps search engines understand frequently asked questions and display them as rich snippets (since 2023, these are only displayed by Google from authoritative government and health websites). This schema should be added on dedicated FAQ pages and all other pages with FAQs, such as service pages, product pages, category pages and blogs. 

Here’s an example of what some simple FAQ schema might look like:

<script type="application/ld+json">

{

  "@context": "https://schema.org",

  "@type": "FAQPage",

  "mainEntity": [

    {

      "@type": "Question",

      "name": "What is SEO?",

      "acceptedAnswer": {

        "@type": "Answer",

        "text": "SEO stands for Search Engine Optimization, a strategy used to improve a website's visibility on search engines."

      }

    },

    {

      "@type": "Question",

      "name": "How can I improve my SEO?",

      "acceptedAnswer": {

        "@type": "Answer",

        "text": "Improving SEO involves optimizing website content, using relevant keywords, improving page speed, and building quality backlinks."

      }

    }

  ]
