The TikTok Commercial Content Library at library.tiktok.com is a free, publicly searchable database of every paid advertisement that has run on TikTok since October 1, 2022. You search by advertiser name, keyword, target country, ad type, or publication date — no TikTok account required. Each result shows the ad creative, the advertiser, first and last shown dates, and, for ads served in the EU, targeting criteria and aggregated audience reach data. Ads remain in the repository for their full run period plus one year after their last impression. The European Commission found TikTok's repository insufficient in May 2025, then accepted binding commitments in December 2025 requiring full in-feed ad content, 24-hour updates, and expanded search filters. TikTok's global ad revenue reached $32.4 billion in 2025 (WARC, via Sepia Lab), making the library the one place to see how a slice of that spend is deployed. CloseFast (closefa.st) uses TikTok ad activity as a prospect-qualification signal alongside Meta and LinkedIn.
What the TikTok Commercial Content Library shows you
Each ad listing in the Commercial Content Library includes:
- Ad creative — the video or image as it appeared in users' feeds, including any link URLs
- Advertiser name — the company or account that ran the ad
- First and last shown dates — when the ad began receiving impressions and when it last appeared
- Target country — the market the ad was served to
- Ad type — the format category
For ads served in the EU, the library additionally displays:
- Targeting parameters — the criteria the advertiser selected, including gender, age group, and Member State where reached users are located
- Aggregated audience reach — estimated unique users reached, broken down by demographic
The library has two sections. The Ad Library holds paid advertisements. The Other Commercial Content section captures posts creators disclosed as commercial through TikTok's content disclosure toggle — branded content and paid partnerships that are not paid ads. This second section is unique to TikTok: no other ad library captures creator-disclosed commercial content alongside paid advertising.
Commercial Content Library vs Creative Center
TikTok has two ad-research surfaces, and confusing them wastes time.
The Commercial Content Library (library.tiktok.com) is a transparency database containing every paid ad that has run on TikTok since October 1, 2022. This is where you look up a specific advertiser and see their full ad history.
The Creative Center (ads.tiktok.com/business/creativecenter) is a marketing tool. It surfaces top-performing ads filtered by region, industry, objective, and format — selected examples, not a complete record. Use it to study what creative patterns are working across a vertical, not to audit a specific competitor.
The practical rule: use the Commercial Content Library to look up a specific advertiser. Use the Creative Center to study what creative patterns work across a vertical. They answer different questions.
EU transparency: what the DSA adds
TikTok was designated a Very Large Online Platform under the EU Digital Services Act in April 2023, based on its self-reported 130 million monthly active EU users (Auditsocials, 2026). Under DSA Article 39, TikTok must maintain a searchable ad repository containing ad content, advertiser identity, run period, targeting parameters, and per-Member-State reach.
In May 2025, the European Commission found TikTok's repository preliminarily in breach of the DSA — it lacked sufficient ad content, targeting, and payer information. On December 5, 2025, the Commission accepted binding commitments requiring full in-feed ad content (including link URLs), 24-hour updates, targeting criteria with aggregated demographic reach, and additional search filters. This is an active compliance cycle — re-check the repository's quality if reading this months later.

How to search the TikTok Commercial Content Library
Search by advertiser name
The most direct path. Open library.tiktok.com, type the brand or advertiser name, and filter by target country and date range. This returns every ad that advertiser has run within the retention window. Use this when you already know the prospect's name. Brand names on TikTok do not always match the legal entity — if a search comes up empty, try variations.
Search by keyword
Keyword search returns ads whose copy or creative contains the term, regardless of advertiser. This maps an entire vertical: search "roofing" or "dental implants" and you see every business in that space currently or recently advertising on TikTok.
Filter by country and date
Always set the region deliberately. EU-targeted ads carry more detail than ads served elsewhere. Match the region to the question you are asking.
The Commercial Content API
Unlike LinkedIn, which has no ad library API, TikTok offers a Commercial Content API returning ad content, advertiser metadata, targeting, and reach data. It is EU-only and requires an application, with a response within two working days. This is the only major platform ad-library API that returns commercial ad data — the LinkedIn Ad Library is browser-only, and Meta's API returns political ads only.
Third-party scrapers like Apify's TikTok Ad Library Scraper also extract from the public pages, but inherit the library's limitations.
What the library does not show
| What you get | What you don't get |
|---|---|
| Ad creative and link URLs | Ad spend or budget |
| Advertiser name | Click-through rate or conversions |
| First and last shown dates | Audience size or exact reach (outside EU) |
| EU targeting parameters | Interest-level or behavioral targeting |
| Aggregated EU demographic reach | Performance metrics (ROAS, CPA) |
| One-year retention after last impression | Ads older than the retention window |
The spend gap is the same across every ad library — the DSA does not require platforms to publish budgets.
How agencies use TikTok ad activity for prospecting
The ad-activity read pattern
A business running TikTok ads is spending deliberately — TikTok's average CPM runs around $9 in 2026 (WebFX, via AffNinja), and ad rates have grown 12.28% year-over-year, nearly twice as fast as Meta's (AffNinja, 2026). The same read patterns apply:
- Long-running active ad (30+ days) — the ad is converting; the company has budget and is investing in TikTok as a channel. Warm prospect.
- Cluster of ads starting the same week — new campaign push, possibly a product launch or new agency hire. Check whether they have tracking set up using the Meta Pixel detection method; new spend plus no tracking means they are flying blind.
- Flurry then nothing for months — lapsed spend. The company tried TikTok ads, stopped, and may not know why. Re-engagement pitch: "your TikTok ads went dark — here's what likely went wrong."
Cross-platform ad audit
TikTok ad activity is one signal. Combining it with the Meta Ad Library, the Google Ads Transparency Center, and the LinkedIn Ad Library gives you the full picture. A prospect running on all four is spending at scale; one running only on TikTok is focused on consumer video; one running only on LinkedIn is B2B. The pitch changes accordingly.
Our guide to seeing what ads a company is running covers the cross-platform method — the TikTok CCL is the short-form-video layer in that stack.
TikTok CCL vs Meta Ad Library vs LinkedIn Ad Library vs Google ATC
| Feature | TikTok CCL | Meta Ad Library | LinkedIn Ad Library | Google ATC |
|---|---|---|---|---|
| URL | library.tiktok.com | facebook.com/ads/library | linkedin.com/ad-library | adstransparency.google.com |
| Login required | No | No | No | No |
| Search by | Advertiser, keyword, country, ad type, date | Page name, keyword, country, date | Company, payer, keyword, country, date | Advertiser name, domain, date, location |
| Retention | Run period + 1 year | EU/UK: 1 year; ordinary: while active | 1 year after last impression (from Jun 2023) | Per DSA; global: while active |
| Spend shown | No | No (political: range) | No | No |
| EU targeting detail | Yes | Yes | Yes | Yes |
| Official API | Yes (EU-only, application-gated) | Political/issue ads only | No | EEA only, under ATC terms |
| Best for | Short-form video prospecting | Consumer/DTC prospecting | B2B prospecting | Search and display ad research |
All four are free, public, and require no login to search. For agency work, use all of them — a prospect's full ad footprint is split across platforms, and checking only one misses the picture.
Bottom line
The TikTok Commercial Content Library is the only free, public tool that shows you what businesses are advertising on the platform that grew from zero to $32.4 billion in ad revenue in five years. It costs nothing, requires no account, and retains a year of history. Its limits — no spend, no performance data — are the same limits every ad library has. What it gives you is the creative, the advertiser, the targeting, and for EU ads the audience demographics — enough to qualify a prospect, read a competitor's creative strategy, and write a pitch that references what they are actually running.
