The Meta Ad Library: how to search ads and what they tell you

What the Meta Ad Library is

Meta publishes every active ad on its platforms in one searchable place, at facebook.com/ads/library. It was built as a transparency measure, first for political advertising and then for all ads, and it used to be called the Facebook Ad Library. Both names refer to the same tool.

For marketers it has become the standard way to see a competitor's advertising. There is no cost, no approval process, and for most searches no login. If a business is paying to show an ad on Facebook or Instagram today, that ad is in the library.

How to search ads in the Meta Ad Library

1. 01

   Open the library and choose a country

   The country selector decides which ads you see. An advertiser running different campaigns in Australia and the United States will show different ads under each, so check the markets you compete in.
2. 02

   Choose an ad category

   Pick All ads for ordinary commercial research. The other categories, such as issues, elections or politics, are narrower and carry extra disclosures.
3. 03

   Search by advertiser or by keyword

   Type a brand name and pick the matching Page from the suggestions to see everything that advertiser is running. Or type a keyword to find ads from any advertiser whose copy mentions it. Put a phrase in quotation marks to match the exact wording.
4. 04

   Narrow the results with filters

   Filter by language, by platform (Facebook, Instagram, Messenger, Audience Network), by media type (image, video, or neither), by whether the ad is active, and by the dates it was shown.
5. 05

   Open an ad to see its details

   Each listing has its own Library ID and a details view. That is where you find the other versions of the same ad and any extra disclosures.

What each listing shows

Ads about social issues, elections or politics are kept for seven years and show who paid for them. Ads delivered in the European Union are kept for a year after they last ran and show reach and targeting information, because EU law requires it.

How to read an ad you cannot see the results for

The library will never tell you an ad is working. It does leave clues, because advertisers tend to stop paying for ads that lose money.

• How long it has run. An ad that has been live for months has survived many budget reviews. An ad that started this week is still a test.
• How many versions exist. Several variations of one idea mean the advertiser is investing in it and looking for the best execution.
• What gets repeated. When the same hook, offer or layout shows up across many of a competitor's ads, it is the message they believe in.
• Where it sends people. The destination shows what they are selling hardest: a product page, a quiz, a free trial, a lead form.
• What changed. A competitor that swaps discount ads for testimonial ads has learned something. The change is often more useful than any single ad.

Where the library falls short

• It is a search tool. It does not watch anyone for you, so you only learn about a new ad when you go and look.
• Results are not ranked by quality. A strong ad and a weak one look the same in the list.
• There is no way to keep notes, compare this week with last week, or share a shortlist with a colleague inside the tool.
• It shows you what a competitor made. Making your own version is still a separate job.

A simple weekly routine

Pick three to five competitors. Once a week, open each one's ads, sort out what is new, and write down one sentence for each new ad: the hook, the offer and the format. After a month you will have a clear picture of what each competitor keeps coming back to, which is a better brief for your next ad than a blank page.
