Structured data

Search engines use HTML microdata specifications (or structured data markups) to better understand the content of a site and create rich snippets in search results (which helps increase click-through rate to a site).

Best practice

• View Google's guide for getting started with microdata: How to structure data.
• Check the Google Search Gallery for structured data you might want to use.
• Check this starter guide.
• Find here the schema hierarchy and here the schema documentation.
• Test your structured data with this testing tool.
