What EcomFilter does
Most ads in the Facebook Ad Library don't lead to a store you can learn from. EcomFilter checks where each ad goes and clears the rest out of the way.
Only Shopify stores
Every ad's landing page is checked. Lead forms, app installs, marketplaces, affiliate pages and dead links are hidden.
One card per product
When a store runs the same creative ten times, you see it once, with a count of how many more there are.
Nothing hidden for good
Press Show to bring back what was hidden and see why. You can always check the filter's work.
How to use it
- Add EcomFilter to Chrome from the Chrome Web Store.
