Structured data

What is Structured Data?

Structured data is a standardized format for providing additional information about web pages to search engines, social media platforms, and other applications. It uses a specific vocabulary, called schema markup, to provide context and meaning to different types of content on a web page. 

Structured data helps search engines and other applications to better understand the content of the page and display relevant information in search results and other applications. Various Google’s SERP enhancements, such as recipes, ratings, local results, shopping results, etc., are all based on the structured data that it finds on pages.

Schema markup can be added to HTML code in a few formats:

• JSON-LD (the most common one)
• microdata
• RDFa

Structured data includes almost 800 types, such as Article, Product, Event, Review, etc. However, not every type is supported by Google. Use Google’s documentation to check what structured data Google search understands.

How to find structured data on pages?

Structured data in the page’s HTML code is relatively hard to read because, most often, it is not “beautified” and consists of barely readable lines of code.

You can use Ahrefs SEO Toolbar - our free extension - which will show pages’ structured data in a more readable and structured way.
