Check My Ads

The Check My Ads Institute is an organization founded by Nandini Jammi and Claire Atkin. The Check My Ads Institute is a non-profit advertising watchdog organization created in October 2021, which aims to bring transparency and accountability to the advertising technology industry. Jammi and Atkin previously published a newsletter called Branded. The Check My Ads Agency was a brand safety and marketing consultancy that Atkin and Jammi founded in 2020. As of February 2023, the Check My Ads Agency is no longer active.

Atkin and Jammi originally focused primarily on the issue of advertisements displaying on websites they describe as "bad faith publishers": websites containing fake news, medical misinformation, and conspiracy theories, or websites engaged in advertising fraud. Many companies are not aware specifically where their advertisements display due to the complexity and lack of transparency in online advertising; the Check My Ads Institute researches the online advertising industry, and pushes for increased transparency and choice. The Check My Ads Agency aimed to help companies learn more about where their products or services are advertised and avoid advertising on harmful websites.
