The TikTok Ad Library is part of TikTok's Commercial Content Library at library.tiktok.com, a searchable record of ads shown on TikTok, and you don't need a TikTok account to use it. It currently includes ads available to users in the European Economic Area (EEA), Switzerland and the UK, so a campaign that only ran elsewhere won't be in it.
That coverage point is the thing most people miss. If you're in the UK or Europe, it's one of the most useful free research tools TikTok offers. If you're researching US, Canadian or Australian campaigns, you'll often come up empty and wonder what you did wrong. Here's how it works, from TikTok's own help, as of October 2026.
What's in TikTok's Commercial Content Library
The Commercial Content Library (CCL) is a repository of ads and other commercial content posted on TikTok. It has two parts:
| Part of the library | What TikTok says it holds |
|---|---|
| Ad Library | Ads TikTok is paid to display, active or paused; any ad with at least one view, kept for one year after its last view |
| Other commercial content | Posts TikTok isn't paid to display that creators disclosed as commercial; kept for one year after deletion or going private |
| Coverage | Ads available to users in the EEA, Switzerland and the UK |
| Account needed | No, library.tiktok.com is open to everyone |
| Delay | Ads generally appear within 24 hours of the campaign starting |
| Reach shown | An estimated range of unique users, plus a targeting summary and a country split |
The Ad Library includes ads that aren't active any more or that the advertiser has paused, which is handy when you want to see what a competitor ran last season, not just today.
How to search the TikTok Ad Library
- Go to the Commercial Content Library at library.tiktok.com.
- Choose Ad Library at the top.
- Pick an Ad target country, an Ad type and an Ad published date.
- To find a keyword or an advertiser, type an advertiser name or keyword.
- Click Search.
You can then sort the results by audience size, last shown date and published date.
What an ad's details page tells you
Click into an ad and TikTok shows you:
- Advertiser. This may link to a verified account. TikTok notes the registered business name can differ from the brand name you know, so search both if you come up short.
- Ad paid for by. Shown when someone else paid, such as a creator network.
- Advertiser's registered location.
- First shown and Last shown dates.
- Unique users seen. An estimated range, not an exact figure.
- Targeting summary. An estimate of the users who met criteria such as age, gender, location and interest.
- Location. The countries the ad was shown in and unique users by country.
Some ads carry a label saying they were removed for violating TikTok's terms. You can't watch those, but you can still see details such as unique users seen and the targeting summary.
How long ads take to appear and how long they stay
TikTok says ads generally appear in the library within 24 hours of a campaign starting. It can also take up to 24 hours after the first view, or after a change to the ad or campaign, for the library to catch up. So if you've just launched and can't find your ad, give it a day. The Ad Library holds any ad with at least one view for one year after its last view, along with any ad targeted at users in the EEA, Switzerland or the UK.
Searching creator posts in Other commercial content
The second part of the library is for organic posts that promote a brand, product or service but that TikTok isn't paid to show. Only content a creator disclosed as commercial through the content disclosure setting is included, and it needs at least one view while it was public. To search it:
- Go to the Commercial Content Library and choose Other commercial content at the top.
- Pick a Creator country and a Posted date.
- Enter a creator username if you're after a specific creator.
- Click Search, then sort by video views or posted date.
Each result shows the username, the brand tagged in the post, the posted date and video views. Some creators show more here than on their profile, because they've deleted or privated videos. TikTok keeps each item available for one year after the creator deletes it or makes it private.

If you're researching ads outside Europe and the UK
Because the library is built around ads available in the EEA, Switzerland and the UK, it won't give you the full picture for campaigns that only ran elsewhere. For top-performing ads more widely, TikTok's own TikTok Creative Center is the tool to use, and I've also rounded up the best TikTok ad spy tools if you want more filters.
How I'd use it for competitor research
Start with your three closest competitors and search by both their brand name and their registered business name. Look at the First shown and Last shown dates: an ad that's run for months is worth studying, because advertisers rarely keep paying for something they've given up on. Treat Unique users seen as a rough band, not a score, since TikTok only gives an estimated range. And check the targeting summary to see who a competitor is going after. If you're researching across platforms, the same habits work in the Facebook Ads Library.
If you advertise on TikTok yourself, you create a TikTok Ads Manager account through TikTok for Business, and any ad you run to users in the EEA, Switzerland or the UK will show up in the library too. It's worth a look at your own entries, so you know exactly what your competitors can see.
Advertisers checking competitor ads often wonder about the music too, and the TikTok Commercial Music Library explains the licensing side.
Frequently asked questions
Is the TikTok Ad Library free?
TikTok says the libraries are available to everyone and you don't need a TikTok account to access, search or use them. Go to library.tiktok.com.
Why can't I find an ad in the TikTok Ad Library?
The library currently includes ads available to users in the EEA, Switzerland and the UK, so ads that only ran elsewhere won't appear. New ads generally take up to 24 hours to show.
How long does TikTok keep ads in the Ad Library?
TikTok keeps any ad with at least one view for one year after its last view, including ads that are paused or no longer active.
Does the TikTok Ad Library show impressions or ad spend?
It shows Unique users seen as an estimated range, plus a targeting summary and unique users by country. It doesn't show exact impressions.
What is Other commercial content in the TikTok library?
It's posts that promote a brand, product or service which TikTok isn't paid to show, where the creator turned on the content disclosure setting.
