Fact Checks Markup
If you have a web page that reviews a claim made by others, you can include a
ClaimReview structured data element on your web page. This element enables Google Search results to show a summarized version of your fact check when your page appears in search results for that claim.
Imagine a page that evaluates the claim that the earth is flat. Here is what a search for “the world is flat” might look like in Google Search results if the page provides a
ClaimReview element (note that the actual visual design may change).
