Facebook Ad Library: How to Research Competitor Ads

Facebook Ad Library is Meta’s public database of ads running across Meta products. An advertiser can use it to find active competitor ads, study their offers and creative patterns, and build better ideas for testing.

It does not reveal normal advertisers’ spend, clicks, sales, or return. Treat it as a source of clues—not proof that an ad performs well.

What is Facebook Ad Library?

Meta created Ad Library to make advertising more transparent. For ordinary commercial ads, it is most useful for seeing which ads a Page is currently running and, in some cases, ads that recently stopped running.

You can often inspect:

• Primary text
• Headlines
• Images and videos
• Ad formats
• Platforms where the ad may run
• Start date
• Multiple versions associated with an ad
• Landing-page links or calls to action

Additional transparency information is available for ads about social issues, elections, or politics. Do not assume those disclosures apply to every commercial ad.

How to search Facebook Ad Library

1. Open Facebook Ad Library.
2. Choose the target country.
3. Select the appropriate ad category.
4. Search for the advertiser’s Page or a relevant keyword.
5. Choose the correct Page from the results.
6. Filter by active status, platform, media type, language, or date when available.
7. Open individual ads to review their details.
8. Save observations in a structured research sheet.

Search by Page when researching a known competitor. Keyword searches can return unrelated advertisers that happen to use the same phrase.

What Ad Library can and cannot tell you

This distinction matters. A weak ad can remain active because nobody reviews the account. A strong ad can stop because inventory changed, a promotion ended, or the advertiser created a new campaign.

Start with the business offer

Before studying colors or fonts, record what the ad promises.

Ask:

• What customer problem does it name?
• What outcome does it promise?
• Is there a price, discount, estimate, consultation, or demonstration?
• What makes the offer feel urgent?
• What proof is included?
• What action should the customer take?

For a local service business, “Book today” is not the real offer. The offer may be same-day service, a clear warranty, financing, a waived diagnostic charge, or proof that the company answers quickly.

Study hooks separately from formats

A hook is the idea that earns attention. A format is how the idea is presented.

Do not conclude that “video wins” when the video also contains a stronger offer, a different audience, and more convincing proof. Separate the variables you want to test.

Look for patterns across several advertisers

One competitor can mislead you. Review at least five advertisers in the same category and market where possible.

Create a simple table:

The value is the repeated pattern. If most established advertisers explain financing but nobody shows the service process, a process demonstration may be a useful gap to test.

Use ad age carefully

An ad that has run for a long time may be worth studying because the advertiser has chosen to keep it active. It is still not proof of performance.

Use these labels:

• New: useful for spotting current promotions or new creative directions
• Recurring: useful for identifying evergreen offers
• Long-running: a stronger clue that the advertiser values the ad
• Seasonal: useful for planning future promotional calendars

Do not invent spend estimates based only on how long an ad appears in the library.

Review the landing page too

The ad is only the first step. Open the destination and check:

• Does the page repeat the promise?
• Is the next action obvious?
• Is the page specific to the service or product?
• Does it include proof?
• Is the form or purchase process simple?
• Does the mobile page load and work?

A strong-looking ad can send clicks to a weak page. That is a funnel problem, not a creative win.

Turn research into a testing plan

Do not copy a competitor’s finished ad. Extract the underlying lesson and build an original version around your own offer, evidence, and customers.

A practical process:

1. Collect 20–30 relevant active ads.
2. Group them by offer, hook, format, and proof.
3. Identify the three most repeated approaches.
4. Identify two useful gaps.
5. Choose one variable to test first.
6. Build original ads using the business’s real claims and creative.
7. Measure clicks, qualified customers, and revenue.
8. Record what the test teaches.

For the testing step, use the Facebook Ads creative-testing guide.

A simple research scorecard

Score each concept from 1 to 5:

Suppose a concept receives 4, 5, 3, 4, and 4 points.

4 + 5 + 3 + 4 + 4 = 20 points

The maximum is 25:

20 ÷ 25 × 100 = 80%

The score helps prioritize ideas. It does not predict Meta performance.

Common Ad Library mistakes

• Assuming active means profitable
• Copying a competitor’s words or design
• Reviewing only one advertiser
• Ignoring the offer and landing page
• Treating ad age as spend data
• Saving examples without a test hypothesis
• Comparing different markets as if demand were identical
• Looking only at attractive creative rather than customer response

Frequently asked questions

Is Facebook Ad Library free?

Yes. Meta provides public access to Ad Library. Available filters and disclosures can vary by ad category and market.

Can I see how much a competitor spends?

Not for ordinary commercial ads. Meta provides additional ranges and disclosures for certain social-issue, election, and political ads, but that should not be generalized to all advertisers.

Can I see whether a competitor ad is profitable?

No. Ad Library does not provide normal commercial advertisers’ sales, leads, profit, or return. An active ad is only a clue.

Should I copy a long-running ad?

No. Study the offer, customer problem, proof, and format. Build an original ad using your own brand, evidence, and claims.

How often should I review Ad Library?

Monthly is enough for many businesses. Review more frequently during a major seasonal promotion or active creative-testing cycle.
