How to use the Meta Ad Library to find winning ads
The Meta Ad Library is a free, public tool that shows every active ad running on Facebook and Instagram. You can look up any advertiser to see everything they are running, or search a keyword to see everyone advertising around a theme. It is the best free source of competitor and category research for Meta ads.
The library does not label which ads are profitable, but you can infer it: an ad that has been running a long time, or a concept a brand has cloned into many variations, is almost certainly working. Find those, model their structure, and rebuild them in your brand. Mockingbird does the modelling for you from a hand-curated version of this research.
How to use the Meta Ad Library
- 1
Open the Ad Library
Go to the Meta Ad Library and choose a country. Use the All ads category for the broadest view.
- 2
Search a brand or a keyword
Search an advertiser name to see one brand's active ads, or a keyword to see a whole category advertising around a theme.
- 3
Filter to active ads
Focus on ads that are live now, and note when each one started running.
- 4
Look for longevity and repetition
The oldest still-running ads, and concepts cloned into many variations, are the ones the brand is spending on. That is your signal of a winner.
- 5
Save the structure
Capture the hook, the layout and the format of the ads you rate. That structure is what you will reuse, not the assets.
- 6
Rebuild it in your brand
Recreate the structure with your product, colours and copy, or heart it in Mockingbird and let it remake it for you.
What the Meta Ad Library shows
For every active ad it shows the creative, which platforms it runs on, and when it started. A single advertiser often has many ads live at once, which lets you see not just one ad but their whole testing approach.
How to read it for winners
Two signals matter: longevity and repetition. Advertisers cut ads that lose money, so an ad that has run for months is almost certainly profitable. And when a brand clones one concept into many small variations, that is where they are putting spend. Ignore likes and comments; they are not the same as profit.
Advertiser search versus keyword search
Search by advertiser when you have specific competitors and want to see everything they run. Search by keyword when you want to understand a whole category, or find brands you did not know were advertising against your product.
Turning research into ads
Research is only useful if it becomes creative. Model the structures you found, do not copy the assets, and rebuild them in your brand. The guide on winning Meta ads covers how to model a winner without copying.
Doing it faster
Hunting through the Ad Library by hand works, but it is slow. Mockingbird curates winning ads for you, so you can skip the manual search, heart the ones that fit, and get them remade in your brand.
