How to use the Facebook Ad Library, step by step

The Ad Library is a public Meta website that gathers active ads from Facebook, Instagram and the company's other platforms. It's a way to study the market before you invest.

How to search

  1. Open the Ad Library.
  2. Select the country where you want to sell.
  3. Under category, choose All ads.
  4. Search a niche keyword, a sales phrase or an advertiser's name.

What to search to find offers

Instead of just your niche name, use words common in sales ads, such as free shipping, shop now, money-back guarantee, limited time and instant access, along with your topic.

How to read an ad

Each card shows when the ad started and whether it has several versions. A long running time is a good sign, because few people keep a money-losing ad live for months. Still, it's a signal, not proof of sales.

How to save time

Comparing hundreds of cards by hand is tiring. Prospect Spy works on top of the Library itself: it shows days running and copies on each ad, filters results, searches automatically and downloads the videos and images.
