This is Part 2 of Meta Ads, the operator's way, the free playbook. Every platform claim below was checked against Meta's own help pages in September 2026.

Meta Ad Library

Every ad running on Facebook and Instagram is listed in Meta's Ad Library at facebook.com/ads/library. You can see any business's active ads — the creative, the copy, where it links, and most importantly, the date each ad started running.

  1. Open Meta Ad Library — Set your country and choose All ads.

Choose All ads under Ad category

  1. Search your competitor — Type their name and pick them from the Advertisers list. Don't just press enter — a keyword search returns every ad that mentions the words, including unrelated businesses.

Pick the business from Advertisers, not the keyword line

  1. Scroll their active ads — This is everything they're paying to show right now.

The advertiser's page: every active ad, with a result count

  1. Find what's still running — Look for two things on each card: an old Started running on date, and multiple versions of the same creative.

Nobody keeps paying for an ad that isn't working

The insight

That's the whole trick. A business that watches its numbers kills a losing ad fast. So an ad that has been running for three or four months is very likely paying for itself. And if they've made several versions of it, they're scaling it — that's their winner.

It's a signal, not a guarantee: some big brands run awareness ads that were never meant to pay for themselves directly. That's why you look for both marks — a long run and multiple versions.

Which means it needs to become your winner. Not the ad itself. The thing that makes it work.

Not copy and paste

Copy with taste

Copying a competitor's ad is lazy, it looks cheap, and it usually doesn't work — their audience already knows them, and yours doesn't. What transfers is the structure. For each long-running ad, write down:

Look forAsk yourself
The enemyWhat are they positioning against? A category, a habit, a competitor?
The proofWhat makes the claim believable — numbers, a demo, a comparison, a customer?
The formatStatic, video, carousel? Comparison table, founder to camera, UGC?
The offerWhat exactly are they asking people to do, and what do they get?
The landing pageWhere does the click go, and what does that page do first?
One winning ad, taken apart: name the enemy, prove it in numbers, one format, many cuts

One winning ad, taken apart: steal the structure, not the ad

Same structure, your facts

Make it yours

Now rebuild it with your own material. Keep the five notes; replace every detail with something true about your business. Say you run a meal-prep delivery service, and you've just taken that soda ad apart:

Their adYour version
The enemyTop sodasTakeout
The proof2g of sugar vs. 39g$9 a meal vs. $18 · 45g of protein vs. 22g
The formatAn us-vs-them table, one static imageThe same table — your numbers, your photo
The offerShop now, on AmazonFirst week half off
The landing pageAmazonYour menu, with the same comparison at the top

Same skeleton, nothing copied. Their photos, their wording, their trademarks and their claims stay theirs. The structure is the only thing you take — and every number in your version has to be true, and yours.

  1. Make two or three versions, not one. — They're running four versions of one format for a reason. Keep the structure and change one thing per version — the enemy, the proof point or the first line — so you'll know what made the difference. How many you can afford to test is arithmetic: Part 5.
  1. Let AI draft. You decide. — Give Claude, ChatGPT or Gemini your five notes and the true facts about your business, and ask for ten variations in your voice. Use an image tool such as Gemini or Higgsfield to mock up the layout around your own photos. Two rules: AI never invents a number, and you choose what goes live.
  1. Run it as a real test. — One thing different per version, a decision rule written down before launch, nothing edited mid-flight. Part 7 has the test checklist; Part 6 is the setup.

> Make it a habit. Looking once is interesting. Looking every week is an advantage. Keep a simple board — competitor, ad, start date, versions, what the structure is — and check it weekly. When a new ad appears and is still running a month later, you've just been handed a tested idea.

Frequently asked questions

Is Meta's Ad Library really free?

Yes. It is public at facebook.com/ads/library, needs no login, and lists every ad currently running on Facebook and Instagram, with the date each one started.

Does a long-running ad mean it is profitable?

It is a strong signal, not a guarantee. A business that watches its numbers kills a losing ad fast, so months of run time plus several versions usually means the ad pays for itself. Some big brands run awareness ads that were never meant to pay back directly, which is why you look for both marks.

Can I just copy a competitor's ad?

No, and it usually does not work anyway: their audience knows them and yours does not. What transfers is the structure: the enemy it positions against, the proof, the format, the offer and the ask. Rebuild those with your own true facts.
