Ad library
Also called: Meta Ad Library, TikTok Creative Center
An ad library is a public database of ads currently running on a platform, such as the Meta Ad Library, used to research competitors' creative.
The Meta Ad Library shows every active ad on Facebook and Instagram, searchable by advertiser. Ads that have run for weeks are a hint, not proof, that they are working, since advertisers usually switch off losers. TikTok's equivalent research tool is the Creative Center's top ads section.
