Rules

Picture and video links are not included: they expire and belong to Meta. Link to our ad page or the ad's library_url instead.
Please credit “Data: WinningAds, findwinningads.com”. Be gentle: about one request per second is plenty.
Numbers mean what the methodology says. We never estimate spend or revenue.

Markdown and llms.txt

Every brand, ad, category, winning-products and trending page has a markdown version at /md/… (for example /md/longest-running-facebook-ads), also served when you request the page with Accept: text/markdown. A map for language models is at /llms.txt (longer: /llms-full.txt).
