Know the reliability and bias of the news

Ad Fontes Media helps businesses, consumers, educators, and platforms navigate today’s complex and dynamic news landscape. We provide data, tools, and educational resources for all stakeholders in quality news media
Ad Fontes is Latin for “to the source,” because we rate news by analyzing the source and its actual content. We use a rigorous, reproducible methodology, and a politically balanced team of analysts, to rate that content, both for bias and for reliability.

Ad Fontes Media is a public benefit corporation with a mission to make news consumers smarter and news media better. Currently, we face a crisis of too much junk news.
Junk news is like junk food, and just like junk food has caused massive health epidemics in our country, junk news is causing a massive polarization epidemic.
We are optimistic that together, we can rise to this challenge. It is imperative that we do. And a problem this big requires a multi-pronged solution and participation from all the stakeholders in good journalism.

Brands, Marketers, and Platforms

To help keep their brands safe by supporting good journalism and avoiding junk news.

Brand managers are increasingly concerned about the role advertisers have played in the rise of polarizing news and the struggles of quality journalism outlets. Polarizing content often turns extreme and offensive, causing consumer boycotts and negative brand perception. Today, 43% of media buyers say they avoid news content entirely,* which hurts quality news publishers who keep the public informed. Through our Ad Apex™ line of products and services, Ad Fontes Media assists brands that want to support good journalism and avoid junk news.

To help assess content and improve trust with consumers.

Today consumer confidence in news media is at historically low levels. Simultaneously, more news and news-like sources are emerging – often overtly questioning the reliability of quality sources, and exacerbating the crisis of confidence. The best sources welcome honest and rigorous critical feedback, including independent audits of their content by politically diverse, credentialed news analysts. We welcome opportunities to provide these services, and we offer certification for the very best publishers, whether left-leaning, right-leaning, or centrist.
