NewsGuard's reliability ratings for news and information sources help users make decisions about which news sources to trust—and avoid misinformation and disinformation.

Our ratings, scores, and Nutrition Labels for websites are displayed next to links on search engines and social media platforms and cover all the news websites accounting for 95% of online engagement.

Ratings are conducted by a team of experienced journalists using nine basic, apolitical journalistic criteria. Each site receives a trust score of 0-100, an overall rating level ranging from “High Credibility” to “Proceed with Caution,” and a thorough Nutrition Label report detailing the site’s ownership and financing, content, credibility practices, transparency practices, and history.
