There are a few factors that determine whether a fact check information panel will appear for any given search. Most important, there must be a relevant fact check article available from an eligible publisher. And in order to match a viewer’s needs with the information we provide, fact checks will only show when people search for a specific claim. For example, if someone searches for "did a tornado hit Los Angeles," they might see a relevant fact check article, but if they search for a more general query like "tornado," they may not. All fact check articles must also comply with our Community Guidelines, and viewers can send feedback to our team.
Our fact check information panel relies on an open network of third-party publishers and leverages the ClaimReview tagging system. All U.S. publishers are welcome to participate as long as they follow the publicly-available ClaimReview standards and are either a verified signatory of the International Fact-Checking Network’s (IFCN) Code of Principles or are an authoritative publisher.
