Straight answer: the Facebook Ads Library is a free, public tool from Meta that shows every ad currently running on Facebook and Instagram, including ones you’re not the target audience for, and you can search it by keyword, page name, or country without needing an ad account of your own. It won’t show you spend or results, but it will show you creative, copy, targeting country, and how long an ad has been live, which is more than enough to steal good ideas honestly.
What this tool is (and who built it)
Meta launched what’s now called the Ad Library back in 2019, originally as a transparency measure for political ads after the 2016 US election fallout. It got expanded to cover every advertiser on the platform, not just political ones, which is the version most of us use now. You’ll find it at facebook.com/ads/library and you don’t need to log in to browse it, though you’ll get more filtering options if you do.
It exists because regulators pushed Meta to be transparent about who’s paying for what people see. The side effect, which I don’t think Meta fully planned for, is that it turned into the best free competitor research tool marketers have. You can watch what any brand, big or small, is putting money behind right now, today, without them ever knowing you looked.
What you can see, and what you can’t
You can see:
- The exact ad creative (image, video, or carousel), word for word copy included
- Which Facebook page is running it
- The date the ad first went live
- Which countries it’s showing in
- Whether it’s still running or was paused
- For political and social issue ads specifically, actual spend ranges and reach
You can’t see:
- How much the advertiser is spending on a normal commercial ad
- Click-through rate, conversions, or return on ad spend
- Exact audience targeting (age, interests, lookalikes)
- Which specific ad set or campaign structure it sits inside
That gap matters more than most guides on this topic admit. People treat the library like it’s a spy tool that shows them a competitor’s whole strategy, and it isn’t. It shows you what they’re saying, not whether it’s working.
How to search it, step by step
Here’s the exact process I use when I’m scoping a new market or checking on a competitor before I brief creative for a client:
- Step 1: Go to facebook.com/ads/library and set the country filter first, top left dropdown. If you skip this you’ll get a mess of results from markets that don’t matter to you.
- Step 2: Choose “All ads” as the category unless you’re specifically researching political or issue ads.
- Step 3: Search by page name if you know exactly who you’re checking, or by keyword if you want to see everyone advertising around a topic, for example “AI consultant” or “small business coach.”
- Step 4: Click into any result and hit “See ad details” to get the start date and platform breakdown (Facebook, Instagram, Messenger, Audience Network).
- Step 5: Sort by noting which ads have the oldest start dates within a search, since Meta shows you the launch date on every single ad without you needing a separate tool for it.
- Step 6: Screenshot or save the ones worth studying, because Meta doesn’t give you a proper export function, so you’re doing this manually, which takes about 20 to 30 minutes for a decent competitor scan of five to eight businesses.
A real search I ran for a client, and what it told me
Last year I was working with a client in the personal finance coaching space who wanted to know why their cost per lead had crept up while a smaller competitor seemed to be everywhere. I pulled up the competitor’s page in the library and found 34 active ads running at once, which was already more than I expected from a business that size.
What struck me wasn’t the volume, it was the pattern. Eleven of those 34 ads were near identical, same testimonial video, three different headlines, running in the UK, Ireland, and Australia at the same time. That told me two things: they were running a headline test, and they had a big enough budget to test across three markets simultaneously rather than one at a time. Neither of those things showed up in spend data because there is none to see on a commercial ad. It came purely from pattern spotting inside the library.
We didn’t copy the ad. We copied the structure, one strong testimonial, three headline variants, and tested it for my client across a single market first because their budget didn’t stretch to three. Cost per lead dropped by around 22 percent over six weeks. That’s not the library doing magic, that’s the library showing us a tactic worth trying and us running our own honest test.
The uncomfortable bit nobody mentions about “ad has been running for months”
Every guide to the Ads Library tells you that a long-running ad is a “winning ad” and you should copy it. I want to push back on that a bit, because I’ve seen it go wrong.
An ad staying live for eight months can mean it’s a genuine winner the advertiser hasn’t dared touch. It can also mean nobody at that company is checking the account, the ad is quietly losing money, and it’s still running because the campaign is on autopilot with no end date set. I’ve inherited ad accounts from new clients where a losing creative had been live for over a year, burning roughly £40 a day for no return, simply because the person who set it up left the company and nobody reviewed it. Longevity in the library is a clue, not proof. Treat it as “worth investigating further,” not “definitely works,” and you’ll save yourself from copying someone else’s mistake.
Turning what you find into ads of your own
Once you’ve gathered five or ten ads worth studying, don’t rewrite them word for word, that’s lazy and it’ll look it. Instead, pull out the structural pattern: what’s the hook in the first line, what proof do they use (numbers, testimonials, before and after), and what’s the actual offer or call to action. Those three things are almost always transferable even when the wording isn’t.
If you’re new to building the ads themselves once you know what you want to make, it’s worth reading up on which Facebook ad creator software fits your budget rather than defaulting to the priciest tool because it’s the most talked about one. And if you’re still deciding how you’ll run the campaigns day to day, there’s a good rundown of Facebook ad campaign software options that covers what each one does well and where they fall short.
For anyone just starting out with paid Facebook ads at all, I’d also point you toward a piece on which Facebook advertising apps are worth using for beginners, because half the mistakes I see new advertisers make come from picking a tool that’s built for agencies managing 50 accounts, not a solo business running one campaign.
Where the Ads Library fits alongside other research
The library is one tool in a wider research kit, not the whole kit. Before I finalise a competitor scan for a client, I’m also checking their website, their organic content, and often their hiring pages (a company suddenly hiring three “growth marketers” tells you something a set of ads never will). There’s a broader guide on how to find tools to research what your competitors are doing online if you want to build out that fuller picture rather than relying on the Ads Library alone.
It’s also worth remembering that paid ads are only half the story on Facebook right now. A lot of the same competitors you’re studying in the library are also putting serious effort into organic Reels, and studying their trending hashtags on Facebook Reels will show you what they’re pushing without spending a penny of ad budget. The two things usually work together: the organic content builds the audience, the paid ads convert it.
Practical limits and a few gotchas
A handful of things trip people up when they first use this tool:
- Ads can appear in the library with a delay of a day or two after launch, so brand new campaigns might not show yet
- Small local advertisers sometimes run ads that only appear in the library once they’ve hit a minimum reach threshold, so tiny hyper-local campaigns can be under-represented
- The library only covers Meta platforms, so if a competitor is spending most of their budget on Google or TikTok, this tool tells you nothing about that
- Page names change, and old ads sometimes sit under a page’s previous name if it’s been rebranded, which can throw off a keyword search
None of these make the tool less worth using, they just mean you shouldn’t treat one search session as a complete picture. I run a fresh scan on my main competitor watch list roughly once a month, because ad libraries by nature are always shifting, and what a business was testing in January often isn’t what they’re running by March.

Frequently asked questions
Is the Facebook Ads Library free to use?
Yes, it’s completely free and public, at facebook.com/ads/library, and you don’t need a Facebook ad account, a business page, or even to be logged in to browse most ads on it.
Can competitors see that I’ve been looking at their ads in the library?
No, viewing the Ads Library is anonymous. There’s no notification, log, or trace that tells an advertiser someone looked at their ads, so you can research as often as you like without it being obvious.
Does the Ads Library show how much money a company is spending on ads?
Only for political and social issue ads, where Meta requires spend ranges and reach estimates by law. For regular commercial ads, like most product or service promotion, no spend or performance data is shown at all.
How often should I check the Ads Library for competitor research?
Once a month is a reasonable baseline for ongoing competitive awareness, but if you’re launching a new campaign or entering a new market, do a fresh, focused search right before you brief your creative, since ad libraries change constantly and last month’s scan can already be out of date.
