From guessing to knowing
Most teams spy on competitors the hard way. Monpetitor turns the whole grind into a feed.
The manual way
- Refreshing the Meta Ad Library by hand, brand by brand

The Monpetitor way
- Every competitor's Meta + Google ads, refreshed for you daily
- Proven winners flagged automatically by days-active
- An alert the moment they launch — or kill — an ad

The short version. The rest live on our full FAQ.
Where does the ad data come from?
Only official, public sources: the Meta Ad Library API and Google's Ads Transparency Center. No scraping, no pixels, no fake accounts.
What makes an ad a “Winner”?
Brands kill losing ads fast. Any ad still running after 14+ days is flagged a Winner — a simple, honest signal of what's actually converting.

No. Add a competitor by name or domain and Monpetitor starts watching their Meta and Google ads — nothing to install on your site.
