Ads library: every public ad library in one table

There is no single ads library. Each ad platform publishes its own, and they fall into two groups: a few that cover ads shown anywhere in the world (Meta, Google and LinkedIn), and a longer list that only covers ads shown in Europe, because European law made them exist.

The table below lists every public ad library worth knowing, checked on 4 October 2026: the address, what you actually get, where it works, and our guide to using each one.

Every ads library, compared

YouTube has no library of its own. YouTube ads are in the Google Ads Transparency Center, under the YouTube platform filter.

Why most ad libraries only cover Europe

Article 39 of the EU's Digital Services Act requires very large online platforms to keep a public repository of the ads they show in the EU. Each entry must include the ad, who it was presented on behalf of, who paid, when it ran, the main targeting parameters and how many people it reached, and it must stay up for a year after the ad last appeared. Amazon cites that article by name on its own DSA page.

That is why the TikTok, X, Pinterest, Snapchat, Microsoft, Amazon and Apple libraries are built around the EU, and why Meta, Google and LinkedIn show more for European ads than for the rest.

Two things follow from it.

A competitor that only advertises outside Europe can be invisible. If they never serve an ad in the EU, the EU-only libraries hold nothing on them. On Meta, Google and LinkedIn you will still see the ad, but not who it was aimed at.

European ads are the most revealing ones. If your competitor also runs ads in Europe, look there first. Meta gives reach by age and gender for ads shown in the EU and UK, LinkedIn gives impressions and top targeting for EU ads, and Pinterest lists the interests and age bands an ad was aimed at.

What each library is good for

Meta and Google are the two that matter for most businesses. They are worldwide, they cover the two biggest ad networks, and they are the easiest to search. Start every competitor check with these two.

LinkedIn is the one B2B marketers need. It covers ads worldwide, lets you search by payer as well as advertiser, and keeps ads for a year after their last impression, so you can see what a rival tested last quarter.

TikTok has two tools that do different jobs. The Ad Library is a record of ads shown in Europe, searchable by advertiser. The Creative Center's Top Ads is a showcase of high-performing ads, filterable by country, industry, objective and format. Use the first to watch a named competitor and the second for creative ideas.

Microsoft mostly repeats Google. Microsoft Advertising has a Google Import tool that copies campaigns across, so a rival's Bing ads are often the same ads you already found in the Transparency Center.

X, Pinterest and Snapchat are occasional checks. All three are EU-only, and X gives you a spreadsheet rather than a gallery. Worth a look once a quarter if your customers use them, otherwise skip.

Amazon and Apple are for sellers and app makers. Amazon's library searches by advertiser, creator, brand, author or product name, filtered by date and country. Apple's searches by developer or app, country and date range.

Reddit is not a transparency library. Its Ads Inspiration Library shows ads Reddit chose to showcase, filtered by industry, budget, format and objective. A competitor missing from it proves nothing.

Which ad libraries to check for your business

Pinterest's own ad category filter includes home decor, fashion, beauty, food and drinks, wedding, travel and DIY and crafts. If you sell in one of those, move Pinterest into the monthly column.

What no ads library will tell you

Spend. Meta publishes amounts spent only for ads about social issues, elections or politics. For ordinary commercial ads, no library shows budgets. Every spend number in a third-party tool is modelled; how to tell if a competitor is outspending you covers the signals that work better.

Keywords. Search ad libraries show the ad, not the search term that triggered it.

Results. No clicks, conversions or cost per click, anywhere.

Ads on networks without a library. Programmatic display bought outside Google, native ad networks and podcast ads leave no public record. If you need those, a paid tool is the only route, and the ad spy tools roundup covers which ones are worth paying for.

A monthly routine that takes 30 minutes

1. Write down each competitor's advertiser names. They differ by platform. The Facebook Page, the Google verified advertiser and the LinkedIn company page can carry three different names, and the legal entity in the EU repositories can be a fourth.

2. Check Meta and Google for every competitor. Note new ads since last month, the oldest ad still running, and every landing page they point to. An ad that has run for six months is one that works.

3. Check the platform that matters most in your category. LinkedIn for B2B, TikTok for consumer brands, Amazon for sellers.

4. Screenshot what you find. Meta drops ads from the library once they stop running, unless they were shown in the EU or UK. If you do not keep a copy, your history disappears with them.

5. Once a quarter, run the niche checks. X, Pinterest and Snapchat, only if your customers are there.

Doing it every week

Ours, so judge accordingly. Figo reads three of these libraries for each competitor you track: the Google Ads Transparency Center, the Meta Ad Library for Facebook and Instagram ads, and the TikTok Ad Library. It checks once a week, and when it finds new ads you get an email and a Slack alert, with the creative and the landing page.

It does not cover LinkedIn, Microsoft, X, Pinterest, Snapchat, Reddit, Amazon or Apple ads, so those stay on your monthly list. If your competitors mainly advertise on LinkedIn or Amazon, Figo is the wrong tool and the free libraries above will serve you better. If Google and Meta are where the action is, Figo starts at $49 a month for three competitors, with a 7 day free trial and no card.
