How to access the Meta Ad Library

TL;DR: Go to facebook.com/ads/library in any browser. Pick a country, pick an ad category (Issues/elections, Housing, Employment, Credit, or “All ads”), search by advertiser name or keyword, and you’ll see every ad a page has run — currently live or paused. No Facebook account required.

The direct steps

Open facebook.com/ads/library in your browser. No login required for the public view.
In the top bar, select the country whose ads you want to see. Ad Library is country-scoped — ads run in Germany don’t show in the US view, and vice versa.
Choose an ad category. “All ads” is the default and is what you want for competitor creative research. The narrower categories (Issues/elections, Housing, Employment, Credit) exist because Meta is required by regulators to keep a longer history for those categories.
Search by advertiser name (the Facebook page), product/brand keyword, or exact phrase. Advertiser-name search is more reliable than keyword — keyword matches can be noisy.
Open any result to see the ad’s creative (image, video, or carousel), its text, the platforms it’s running on (Facebook, Instagram, Messenger, Audience Network), and its start date.

That’s the complete workflow for 95% of use cases. You can do it on a phone, a laptop, or programmatically via the Ad Library API if you need to pull data at scale.

Why this matters for creative research

The Ad Library is the single most useful free tool for competitor creative intelligence. Unlike a creative audit of a competitor’s website, the Ad Library shows you specifically what they’re spending money to promote — which filters out the low-effort content and reveals their actual messaging priorities.

Two signals matter most when browsing:

Long-running ads. An ad still active after 30+ days is almost certainly a winner — no brand pays to run a losing ad for a month. Ad start date is visible on every result; sort by it or scan manually.
Variation counts. If a competitor is running 8 versions of the same concept, they’ve found a winning formula and are scaling it. Variation density reveals a winning template faster than individual-ad longevity does.

Both signals feed directly into creative reverse-engineering — you want to start from proven winners, not random ads.

Filters worth using

The Ad Library has several filters beyond country and category. The useful ones:

Platform (Facebook, Instagram, Messenger, Audience Network) — narrows to where you actually advertise.
Ad type (Image, Video, Multiple media, Carousel) — for reverse-engineering, video ads require a different workflow than static; filter accordingly.
Language — useful if you’re researching a brand that runs in multiple markets but you only want one language.
Active/inactive status — active ads are almost always more useful; inactive ones show history but not current priorities.

Two filters sound useful but are less reliable than they look: “Impressions” and “Spend range” are only available for political ads. For commercial ads, you cannot see impressions or spend.

What you can’t see

The Ad Library is transparent but not unlimited:

No impressions or spend on commercial ads. You see that an ad exists, not how many people saw it.
No exact targeting parameters. You can see which platforms an ad runs on, but not the demographic/interest/lookalike audience it targets.
No performance metrics. You can’t see CTR, conversion rate, or ROAS. You infer performance from indirect signals (longevity, variation count).
Political/issue ads have extended history (from 2018 onward). Commercial ads currently only show data from about mid-2022 onward.

For teams doing regular competitor monitoring, combining the Ad Library with a monitoring workflow (daily or weekly checks) compensates for the lack of historical analytics.

Key takeaways

The URL is facebook.com/ads/library, no login needed.
Search by advertiser name, not keyword, when you can.
Use longevity and variation count as your winner signals.
You can’t see spend or performance metrics for commercial ads — you infer them.
For pulling data at scale, the Meta Ad Library API is the programmatic version.
