How To Spy On Your Competitors' Ads (Legally, And For Free)

The Facebook Ads Library shows you every active ad any Page is running, anywhere in the world - no login, no budget, no guesswork required. This cheat sheet walks you through finding your competitors' ads and reading the signals that tell you what's actually working for them.

If an ad has been running for weeks, that's not an accident.

Advertisers kill underperforming ads fast - nobody keeps paying for something that isn't converting. So the ads that have been live the longest are very likely the winners. The Ads Library shows you exactly how long any ad has been running, which turns "what are my competitors doing" into something you can actually measure.

Step 1

Open The Facebook Ads Library

Go to the Meta Ad Library (facebook.com/ads/library) in your browser. You don't need to be logged in, and your competitor won't know you've looked.

Step 2

Search For Your Competitor Or Niche

Search by Page name if you know who you're checking, or by a keyword related to your niche to discover accounts you haven't come across yet. Set the "Ad category" filter to "All ads" and the country to wherever your competitor is running ads.

Running your own ads already?

Search your own brand name too - it's the easiest way to check your current ads are actually live and approved.

Step 3

Check How Long Each Ad Has Been Running

Every ad listing shows a start date. The longer an ad has been running continuously, the more likely it's profitable - most advertisers pause anything that isn't performing within days. An ad still live after several weeks is worth studying closely.

Step 4

Look For Repeated Angles And Multiple Variations

If a competitor is running several ads with the same hook, offer or creative style reworked slightly differently, that's a strong signal they've found an angle that works and are scaling variations of it. A single lonely ad tells you far less than a cluster of similar ones.

Step 5

Study The Creative, Copy And CTA

For each ad worth studying, note: the hook in the first line or first few seconds, the format (video, image, carousel, screenshot-style), the call to action button, and whether it links to a landing page, a lead form or a DM/comment funnel. These are the pieces you'll want to reference - not copy - when building your own.

Funnel Check

Click through to the landing page where you're able to. Seeing the full funnel, not just the ad, tells you much more about what they're actually offering and how they're pricing it.

Step 6

Keep A Swipe File

Save screenshots of the strongest ads you find, sorted by niche or angle. Revisit it before you brief a new ad - most "new" ad ideas are really just a fresh take on an angle someone else has already proven works.

Real Talk

Runtime is the closest thing to a performance metric you'll get for free.

You'll never see a competitor's actual cost per result or return on ad spend - the Ads Library doesn't share that. But how long an ad has stayed live, and how many variations of the same angle a brand is running, are honest proxies for "this is working," because nobody pays to run a loser on purpose.
