TikTok Ad Library search — the Commercial Content Library

TikTok's ad library has a different name

Everyone calls it the TikTok Ad Library. TikTok calls it the Commercial Content Library, and it lives at library.tiktok.com. Searching for the former will get you to the latter, but the distinction matters once you are inside, because the product has two tabs doing quite different jobs.

The ads tab is the transparency archive: paid advertising, searchable by advertiser. The other commercial content tab covers organic posts carrying a paid-partnership disclosure — creator content a brand paid for without buying media. If you are researching a competitor's influencer programme rather than their ad account, the second tab is the one you want, and it has its own separate API.

It is free and open, and no TikTok account is required.

The regional catch nobody mentions

TikTok built this library to satisfy the European Union's Digital Services Act, and the scope of the data follows the scope of the obligation. Searching for a well-known advertiser with the target country set to the United States returns nothing at all. Set the same search to Germany, France, Ireland or the United Kingdom and the results arrive in the thousands.

Try it on Zalando, the European fashion retailer. With the target country set to the United States the library answers with a total of zero and an explanation that the advertiser may not be running ads in the selected country. Change one dropdown to Germany and the same query returns over a thousand ads, filed under the registered name Zalando SE, each carrying first and last shown dates and a unique-users band. Vinted behaves identically: nothing in the United States, more than a thousand in France and in Germany.

That is the first thing to understand about researching TikTok competitors: you are looking at their European advertising. If your competitor runs TikTok only in North America, this library will show you an empty page, and the empty page is not evidence that they have stopped.

The country selector on the form above is limited to the EU, EEA and UK for that reason. Offering the rest of the world would just be a way of generating dead ends.

What the library holds

Within its regional scope, the archive is genuinely deep. TikTok includes any ad that received at least one impression and was published on or after 1 October 2022, whether or not it is still running, and content usually appears within 24 hours of a campaign starting. Ads pulled for policy violations stay in the record as entries, though the creative itself is withheld.

That depth is the mirror image of Meta's design. Meta shows you everything live and forgets most of it; TikTok shows you a narrower slice of the world but remembers it properly. A competitor's abandoned creative from eighteen months ago is still there.

One category is absent by design: TikTok does not permit political or election advertising at all, so there is no political archive and no spend disclosure of the kind Meta and Google publish.

What each ad tells you

Results carry the advertiser's registered business name, the first and last dates the ad was shown, and a band for the number of unique users who saw it — reported as a range like 0-1K rather than an exact count. Open an ad and you also get the audience-size estimate and the targeting parameters the advertiser used, which is more targeting detail than most libraries publish.

No spend figures appear anywhere. The unique-user and audience bands are the closest thing to a scale signal, and they are coarse on purpose.

The advertiser name is where searches go wrong. TikTok matches against the registered business name, which is frequently the legal entity rather than the brand you know — a search for a fashion label may return nothing while its holding company returns hundreds of ads. If a brand search comes back thin, try the company name on their terms of service page.

Its limits as a research tool

The search is keyword-shaped rather than advertiser-shaped, which means a plain query mixes the brand's own ads with every creator and reseller who used the word. There is no saved advertiser, no way to follow one account, and no notification when something changes.

The Zalando search shows this too, if you compare two countries. Set to Germany the results are filed under Zalando SE and are plainly the retailer's own media. Set to the United Kingdom the same query returns a much shorter list dominated by individual creator handles rather than the company — accounts whose posts matched the word, not ads the brand bought. Same query, same brand, two different kinds of answer, and nothing in the interface warns you which one you are reading.

Nor is there an ordinary export. TikTok runs a research API for the ads data, but access is by application, and the download available in the other commercial content tab covers organic branded posts rather than paid ads. For most marketing teams the practical interface is the web page, one screen at a time.

And the pattern that matters — what launched this week, what was killed, what has survived long enough to be working — has to be assembled by hand from dates, every time you look.
