Meta Ad Library

The Meta Ad Library is a transparency tool that lets anyone search the ads currently running across Meta's apps. You can search by advertiser name or keyword, filter by country and see each ad's creative, start date, platforms and how many versions exist.

For ads shown in the European Union, Meta publishes extra details under EU transparency rules, including an estimate of the ad's reach and the audience it was shown to by age, gender and country. See EU ad transparency reach. Ads about social issues, elections or politics keep more history and show spend ranges, but ordinary commercial ads outside the EU show less.

Ecommerce researchers use the library to:

• see every ad a competitor is running right now
• find new products by searching phrases such as "free shipping" or "limited stock"
• judge how long ads have been live, which is a sign of profit

The library is built for checking one advertiser at a time. RivalSonar's ad library collects public ads from Meta, TikTok, Pinterest and Snapchat in one place, links them to the stores they promote and adds active days, an estimated spend and an AI score. The guide on using an ad library for product research shows both approaches.
