Meta Ad Library

The Meta Ad Library is a free, public database run by Meta that lets anyone view ads currently running across Facebook, Instagram, Messenger, and the Audience Network. It is Meta's flagship ad-transparency tool, searchable by advertiser name, keyword, or country, and it shows the live creative, the page running it, and when the ad started.

How it works#

When an advertiser publishes an ad on Meta's platforms, a copy is automatically indexed in the Ad Library at facebook.com/ads/library. For most ad categories you see the creative, the page name, and the launch date. For political and social-issue ads, Meta adds extra detail: spend ranges, impression ranges, and audience demographics. Each advertiser's full set of active ads is browsable, which makes it useful for spotting how many variations a brand is testing.

Why it matters#

The Meta Ad Library is the most widely used Ad Library for social advertising and a cornerstone of modern Ad Transparency. Marketers use it to study competitors' creative angles, messaging, and offer cadence at no cost. Its main limits: it covers only Meta-owned surfaces, hides spend for commercial (non-political) ads, and shows no performance data. For ads outside Meta's ecosystem, equivalents like the Google Ads Transparency Center cover search and display.
