vs. Google Ads Transparency Center

A Google Ads Transparency Center alternative that isn't Google-only

Google's Ads Transparency Center does one thing well: you put in an advertiser and it shows you their ads across Search, Display, and YouTube, going back a while. What it won't do is tell you how those ads compare, or let you search by the ad copy itself instead of an advertiser you already know — and it obviously stops at Google's own inventory. Ad Repository indexes the same four Google surfaces (plus Shopping) alongside Facebook and X, and every ad's numbers get tracked over time instead of shown once and forgotten.
