Short answer: you can see almost every ad your competitors are running right now, for free, in three places: the Meta Ad Library for Facebook and Instagram, the TikTok Creative Center for TikTok, and the Google Ads Transparency Center for Search, YouTube and the rest of Google. Seeing the ads is the easy part. The skill is reading them: working out which ones are actually making money and why.

Most of what you find in these libraries are tests, not winners. Brands launch many ads, keep the few that work and switch the rest off within days. If you copy whatever you see first, you are probably copying a failed test. Here is how I read competitor ads before I plan a campaign for a client.

Where can I see my competitors’ ads?

  • Meta Ad Library (facebook.com/ads/library): choose a country, set the category to “All ads”, then search for the brand’s Facebook Page. You can also open it from the “Page transparency” section of any Facebook Page. Use the filters to show active ads only.
  • TikTok Creative Center (ads.tiktok.com/business/creativecenter): the Top Ads section lets you filter ads by country, industry and campaign objective. It is free and needs no ad spend.
  • Google Ads Transparency Center (adstransparency.google.com): search by advertiser name or website, pick a region, and you will see the Search, YouTube and display ads that verified advertiser has run, with the date each one was last shown.

How do I tell a winning ad from a test?

Look at how long the ad has been running. In the Meta Ad Library every ad shows the date it started running. Nobody keeps paying for an ad that loses money, so an ad that has been live for months is the closest thing you will get to proof that it works.

Then check for these signals:

  1. Age. Sort out the ads that started in the last week or two. Those are mostly tests. The ones that are still running after 30, 60 or 90 days are the ones to study.
  2. Variations of the same idea. When a brand runs several versions of one ad (same angle, different hook, image or format), it usually found something that works and is trying to scale it.
  3. The same message on several platforms. If the angle you saw on Instagram also shows up as a TikTok ad and a YouTube ad, the brand trusts it enough to fund it everywhere.
  4. The landing page. Click through. The offer, price and page the ad sends people to tell you more about the strategy than the ad itself.

What should I take from a competitor’s ad?

Never copy the ad. Take the thinking behind it. For every long-running ad, I write down five things:

  • The hook: what happens in the first line of text or the first seconds of the video, the part that stops the scroll.
  • The angle: which problem, desire or objection the ad speaks to. Price? Speed? Status? Fear of a mistake?
  • The offer: discount, free trial, bundle, guarantee, free delivery, or nothing at all.
  • The format: talking-head video, product demo, carousel, user-generated content, static image.
  • The call to action: what the viewer is asked to do, and where it takes them.

Once you have this for five or six competitors, patterns appear. You will see which angles everyone is fighting over and which ones nobody is using yet. The gap is usually where your best ad is.

How do I use this in my own campaigns?

Turn what you learned into test ideas, not finished ads. If three competitors have run a “how it works” demo video for months, a demo is a strong first test for you, told with your own product, your own proof and your own voice. If everyone leads with price, test leading with something else.

Then judge your tests on your own numbers. What works for a competitor with a bigger brand, a different price or a different audience will not always work for you. Their ads tell you where to start; your data tells you where to put the budget.

What these libraries do not show you

  • Spend and results. Outside political and social-issue ads, you will not see how much was spent or how well an ad performed. Run time is your best clue.
  • Targeting. You see the ad, not who it was shown to.
  • Everything everywhere. The Meta library mainly shows ads that are active now, TikTok’s Top Ads is a selection rather than every ad, and Google only covers verified advertisers. Check all three and treat the result as a sample, not the full picture.

Used this way, a free ad library is some of the most honest market research you can get: it shows you what your competitors are willing to keep paying for. If you would like me to do this research for your market and turn it into a campaign plan, book a consultation.

Frequently asked questions

Is it legal to look at competitors’ ads in these libraries?

Yes. Meta, TikTok and Google publish these libraries on purpose, for transparency, and anyone can browse them. What you should not do is copy another brand’s creative, wording or trademarks. Learn from the strategy and make your own ad.

Do I need an ad account to use them?

No ad spend is needed. The Meta Ad Library and the Google Ads Transparency Center are open to anyone, and the TikTok Creative Center is free to use.

How do I know if a competitor’s ad is working?

You cannot see their results, so use how long the ad has been running as the signal. An ad that stays live for weeks or months, especially with several variations, is very likely profitable for them.
