Google ad library - Spy best ads of your competitors

After downloading this extension, go to the Google Ads Transparency Center and see the dates on the ads using the best-performing ads filter. Ads Date Intelligence — Competitor Ad Timeline Intelligence for Google Ads Stop guessing which competitor ads are working. Ads Date Intelligence overlays the Google Ads Transparency Center with a real-time intelligence dashboard and features an instant on-site scanner—so you can see exactly which creatives have survived long enough to be profitable, and which were killed after a week. Built for media buyers, PPC agencies, and growth marketers who are tired of copying ads that were already paused. Key Features: Instant On-Site Ad Scanner No need to jump between tabs. While browsing any website, click the extension to instantly scan if that domain is running Google Ads. If ads are detected, the extension extracts and presents their live Google Ads details right there on the page. Instant "Battle-Tested" Detection Filter for ads that have been running 90+ days with a single click. If a competitor is still paying to run it, it's almost certainly working — and now you'll know before you spend a dollar testing your own version. Full Timeline View per Advertiser See the precise First Seen and Last Shown dates for every ad in your niche. Track when competitors launch new creative waves and how long each angle holds before fatigue sets in.

Know exactly when to refresh your own copy and visuals before performance drops — based on hard data from real campaigns, not guesswork.
