Ad-library research (no account needed)
Every major platform publishes the ads running on it as an official transparency tool, for exactly this kind of research. This skill is the map: where each library is, what it can filter, what it hides, and how to turn a pile of ads into something a marketer can use.
Where to look
| Library | URL pattern | What it shows | Limits |
|---|---|---|---|
| Meta Ad Library (Facebook, Instagram, Messenger, Threads) | https://www.facebook.com/ads/library/?active_status=active&ad_type=all&country=US&q=<brand or keyword>&search_type=keyword_unordered |
creative, copy, start date, platforms; EU results add reach and targeting | no spend for non-political ads; "active" vs "all" matters, because the longest-running ads are the proven winners |
| Google Ads Transparency Center | https://adstransparency.google.com/?region=US&domain=<brand.com> |
Search, Display, YouTube creatives by advertiser or domain, with first/last-shown dates | no copy for many Search ads unless you open each; filter by format |
| TikTok Creative Center (Top Ads) | https://ads.tiktok.com/business/creativecenter/inspiration/topads/pc/en |
top-performing TikTok ads by region, industry, objective, with likes and CTR proxies | curated sample, not the whole library |
| TikTok Ad Library (EU transparency) | https://library.tiktok.com/ads?region=all |
every ad shown in the EU, searchable by the advertiser's LEGAL entity name | search is exact on the registered entity ("Duolingo, Inc."), EU only |
| LinkedIn Ad Library | https://www.linkedin.com/ad-library/search?companyName=<Company> |
B2B ads by company or keyword, with impressions by country | needs a signed-in LinkedIn session in the browser |
| Snap political/issue ads | https://www.snap.com/en-US/political-ads |
political and issue ads with spend | political only |
Use these the way a person does
Open the pages in a normal browser session, one query at a time, and read what they show. These are transparency tools the platforms publish for the public; their terms prohibit scripted bulk collection, scraping, or working around rate limits, so do not automate requests against them from the agent. For automated, licensed research use a tool built for it.
