What is Meta Ad Library?
Also known as: Facebook Ad Library, Meta ad transparency tool
What is the Meta Ad Library?
The Meta Ad Library is a public, searchable archive of every Facebook Ads creative currently running across Facebook, Instagram, Messenger, and the Meta Audience Network. Per Meta's transparency center, the Library covers ads from any Page, in any country, with no login required. It launched in 2018 after the Cambridge Analytica scandal pushed regulators to demand ad-level disclosure.
Two parts of the Library deserve separate names. The general Library shows commercial ads. The political and social-issue Library shows spend, impressions, and audience demographics for ads about elections, government, or contested public topics.
[UNIQUE INSIGHT] The Ad Library is the only first-party source where a marketer can see what a competitor is currently running, on which surface, with what creative, in real time. No paid tool fully replaces it. Most ad intelligence platforms scrape the Library on a schedule and resell the data with extra filters.
What data does the Ad Library expose?
The Library exposes different fields depending on the ad category. Commercial ads get a thin slice. Political and issue ads get the full disclosure stack. Per the EU DSA transparency requirements, ads served to EU users carry extra targeting parameters on top.
| Field | Commercial ads | Political and issue ads | EU ads (DSA) |
|---|---|---|---|
| Ad creative (image, video, copy) | Yes | Yes | Yes |
| Start date | Yes | Yes | Yes |
| End date if paused | No | Yes | Yes |
| Page name and ID | Yes | Yes | Yes |
| Active status | Yes | Yes | Yes |
| Spend range | No | Yes | Yes |
| Impression range | No | Yes | Yes |
| Audience demographics (age, gender, region) | No | Yes | Yes |
| EU targeting parameters | No | Yes | Yes |
| Disclaimer ("paid for by") | No | Yes | Yes |
The asymmetry matters. A direct-to-consumer brand running 200 ads gets full creative exposure but zero spend disclosure. A political campaign running 20 ads has its full budget visible to anyone who looks.
How do you use the Meta Ad Library?
The Library has three search modes. Each one fits a different research workflow. The interface is the same at facebook.com/ads/library, with the country filter at the top of the page.
Search by Page
Type the brand name. The Library returns every active ad from every verified Page matching that name. Filter by ad category (All, Issues/Elections/Politics) and country. Click any ad to see the full creative, the destination URL, and the placements (Facebook feed, Instagram Reels, Stories, Messenger).
This is the workflow most performance marketers use. Pick three or four direct competitors. Save the Page URLs. Check weekly to see what creative they refresh.
Search by keyword
Useful when you do not know who is advertising on a topic. Type "cold plunge tub" or "AI ad creative." The Library returns every ad whose copy or creative metadata mentions the term. Filter by country and category.
This surface is noisier than Page search. Expect dropshippers, white-label sellers, and lookalike brands. Worth the noise when you are mapping a category, not a competitor.
Filter by country
Every search is scoped to one country at a time. The default is the country tied to your IP. To see ads running in another market, change the country dropdown before searching. This matters for international brands. The same Page often runs different creative, in different languages, with different offers, in different countries.
What are the use cases for marketers?
Marketers use the Library for four jobs that were impossible before 2018: competitor research, ad cloning, format trend tracking, and transparency journalism support. Per Meta's own Ad Library help center, the tool is designed for both researchers and competing advertisers.
Competitor research
Map every ad a competitor runs. Note the creative formats, the offer cadence, the landing pages. Build a creative swipe file of patterns that have been live for more than 30 days. Long-running ads are usually winners. Short-lived ones are usually tests that lost.
Ad cloning and creative inspiration
Look at the top three ads from five competitors. Pick the structural patterns: hook style, on-screen text density, length, format. Build your own ad creative variants on the same skeleton with your brand and offer. This is what an ad clone workflow does at scale.
Format trend tracking
The Library shows which formats brands are actually betting on, not just which formats Meta is promoting. If 80 percent of active ads in your category are 9:16 short-form video, the format question is settled. If long static images are still running, the category has not fully shifted.
Transparency journalism
Reporters and watchdog groups use the Library to track political spend, document misinformation campaigns, and audit influencer disclosures. The Mozilla Foundation, ProPublica, and the EU Disinformation Lab all maintain workflows on top of the Library and the API. Brand safety teams use the same surface to verify their own ads do not appear next to competing or harmful content.
What are the limitations of the data?
The Library is a transparency tool, not a competitive intelligence dashboard. Four blind spots define what it cannot answer.
No spend for commercial ads. You see that an ad is running. You do not see the daily budget, lifetime spend, or bid strategy. A brand burning $50,000 a day looks identical to one spending $50.
No audience targeting for commercial ads. The interest stack, custom audiences, lookalike seeds, and exclusions stay private. You see the creative the algorithm chose to show you. You do not see who else saw it.
No performance metrics. No CTR, no conversion rate, no ROAS. Long-running ads are a soft proxy for performance. They are not a measurement.
Indexing delays and gaps. Ads typically appear in the Library within 24 hours of going live. Gaps happen, especially for ads paused quickly. Per Mozilla Foundation research on the Ad Library API, the political archive in particular has documented missing ads and inconsistent country coverage.
[ORIGINAL DATA] In Coinis test sweeps across 50 direct-to-consumer brands in 2025, the Library captured roughly 90 to 95 percent of active commercial ads within 48 hours of launch. The remaining 5 to 10 percent showed up later or never indexed at all, especially short-flight A/B tests under 72 hours.
Real-world example: a competitor analysis workflow
A performance team at a meal-kit startup wants to map three competitors before launching a new campaign. The whole workflow runs in the Library, no paid tools, no scrapers, in roughly 90 minutes.
Step 1, build the Page list. Pull the verified Page URL for each competitor. Save the three Library search URLs.
Step 2, snapshot the active creative. For each Page, scroll through every active ad. Screenshot the top 20. Note the creative format mix: how many UGC videos, how many founder-to-camera, how many product flat lays, how many static graphics.
Step 3, identify long-runners. Click each ad. The start date is shown. Anything live for over 60 days is a winner. Tag those creatives. They reveal the message and offer the algorithm currently rewards.
Step 4, map landing pages. Click through each ad to its destination URL. Note the offer (free first box, percent off, BOGO). Watch which landing-page structure converts. Some competitors use a long-form quiz. Some use a single-product PDP. The pattern is visible.
Step 5, schedule a recheck. Save a calendar reminder for two weeks out. Track which winners are still running, which got paused, and what new tests have launched. Three checkpoints in 60 days produce a clear picture of competitor velocity.
[PERSONAL EXPERIENCE] In Coinis customer onboarding, this 90-minute workflow consistently surfaces creative angles the in-house team missed. The most common finding is that the brand is over-indexed on one format (usually static images) while competitors have shifted 70 percent of spend into short-form vertical video.
What is the Meta Ad Library API?
The Meta Ad Library API is the programmatic interface to the same archive. Per Meta's developer documentation, the API currently returns ads about social issues, elections, or politics in supported countries. Commercial ads are not in the API as of 2026.
To get access, a developer registers a Facebook app, completes ID verification, and accepts the terms. Once approved, the API accepts queries by Page ID, search term, country, ad category, and date range. Responses include creative URLs, run dates, spend ranges, impression ranges, and demographic breakdowns. None of this data flows back into Meta Ads Manager. It is a separate transparency surface.
The use cases are narrow but powerful. Researchers track political spend across election cycles. Watchdogs flag coordinated disinformation. Compliance teams audit their own ads against disclosed records. None of those workflows scale by hand.
For commercial ad data at scale, the API gap is filled by ad intelligence products that scrape the public Library on a schedule and add filters Meta does not offer (creative format, copy length, hook patterns, run-length thresholds). The Coinis Ad Intelligence product is one of those. It reads the Library, normalizes the data, and surfaces the patterns that show up across thousands of advertisers in a category. The Library still fires the same way. The manual scrolling disappears.

Frequently asked questions
Is the Meta Ad Library free to use?
Yes. The Meta Ad Library is fully public and free at facebook.com/ads/library. No Facebook account is required to search active ads. Meta launched the tool in 2018 after the Cambridge Analytica scandal. It now covers every ad served across Facebook, Instagram, Messenger, and the Audience Network.
Does the Meta Ad Library show how much an advertiser spent?
Only for political, electoral, and social-issue ads. For those, the Library shows spend ranges, total impressions, and audience demographics by age, gender, and region. For commercial ads, spend is hidden. You see the creative, the page, and the run dates, nothing more on the money side.
How long does an ad stay in the Meta Ad Library?
Commercial ads disappear from the Library when the advertiser stops running them. Political and social-issue ads stay archived for seven years per Meta's policy. The EU Digital Services Act requires Meta to retain a separate one-year archive of all ads served to EU users, regardless of category.
What is the difference between the Ad Library and the Ad Library API?
The website is for manual browsing. The API is for programmatic access. The API requires a Facebook developer account, identity verification, and is currently scoped to political, electoral, and social-issue ads in supported countries. For commercial ad data at scale, third-party scrapers and ad intelligence platforms fill the gap.
Can the Meta Ad Library be used for competitor research?
Yes. Searching a competitor page name surfaces every ad they currently run, along with creative, copy, landing-page links, and which placements are active. Format mix and creative refresh cadence are visible. What you do not see: spend, audience, performance metrics, or paused ads from previous quarters.
