Search the public ad libraries. Meta's Ad Library shows ads running across its apps, Google's Ads Transparency site covers Search, Display, Gmail and YouTube, and TikTok offers a Commercial Content Library and a Top Ads gallery.
Where to look
- Meta Ad Library: search active ads across Meta products at facebook.com/ads/library. Ads about social issues, elections or politics are kept for seven years, with spend ranges and reach.
- Google Ads Transparency: search by advertiser or website name, then filter by date and location.
- TikTok Commercial Content Library: covers ads shown in the European Economic Area, Switzerland and the UK. No account is needed. It shows the advertiser, first and last shown dates, a range of unique users and a targeting summary.
- TikTok Top Ads: high-performing ads you can filter by region, industry and objective. Only ads that advertisers have authorised appear.
What you will not see
The libraries show the creative and some delivery details, not results. Spend appears only for certain ad types, such as Meta’s political ads. Treat what you find as creative research, not a performance benchmark.
In practice
For apps and games, search the developer name as well as the app name, since ads often run under the company. Log the hooks, formats and calls to action you see, and note which ads keep running for months. Then test your own versions instead of copying.
