YouTube ad library: where any brand's YouTube ads actually live

Search "YouTube ad library" and you'll find a page of paid spy tools all claiming to be it — because there is no standalone YouTube ad library. The real one is hiding in plain sight: YouTube ads are Google ads, and every one of them sits inside the official Google Ads Transparency Center under the video format filter. We track 110,145 Google creatives across 145 UK brands, 25,187 of them video, so this guide covers both how to pull a rival's YouTube ads out of the official tool and what that much real video data says about how UK brands actually use the channel.

Is there a YouTube ad library?

Yes — it just isn't called that, and it isn't a separate product. YouTube doesn't operate its own transparency tool the way Meta, TikTok and LinkedIn do. Instead, ads served on YouTube are disclosed through the Google Ads Transparency Center, which Google launched in March 2023 to cover Search, YouTube and Display in one searchable hub. Filter any advertiser's page to the video format and you are, for all practical purposes, looking at their YouTube ad library.

That's the whole answer, and it's worth saying plainly because the search results for this query mostly won't. The tools ranking for "YouTube ad library" are third-party databases that scrape or estimate YouTube activity and sell access. Some are decent inspiration galleries; none of them is official, and none shows you more UK YouTube inventory than Google's own free tool — they differ on packaging (saved boards, spend estimates, US coverage), not on access to some secret dataset.

How to search YouTube ads in the Ads Transparency Center

1. Go to adstransparency.google.com. It's free and needs no account.
2. Search by website domain rather than brand name — it's far more precise. Advertiser-name search ranks by ad volume, and a big foreign entity with a similar name can outrank the company you actually want.
3. Verify the advertiser entity: check the verified legal name, location and payer name before reading anything into the ads. One brand often maps to several advertiser accounts.
4. Set the region (United Kingdom for UK-served ads) and the time window.
5. Set Format → Video. Everything left is the brand's YouTube output for that region and period.
6. Click any creative for its first-shown and last-shown dates and the regions it ran in. Video entries link through to a YouTube watch page — frequently an unlisted video that exists only as ad inventory, which is exactly why you never found it by searching YouTube itself.

What you won't get: spend, impressions (outside the EU), clicks, or view-through anything. For ads served in the EU the Digital Services Act forces extra disclosure — targeting parameters and recipient counts, per Google's transparency documentation — so if a brand runs the same campaign in Ireland or Germany, the EU listing can tell you things the GB one won't.

What 25,187 real video creatives say about UK YouTube advertising

The Transparency Center shows you creatives one advertiser at a time and aggregates nothing. We capture and AI-qualify brands' live ads continuously — 110,145 Google creatives from 145 UK brands so far, 25,187 of them video — which makes the shape of the channel measurable. Three patterns matter before you read anything into a single rival's video grid.

1. Video commitment varies enormously — check before you assume

Across our dataset video is 23% of Google creatives, but that average hides a split. At one end, some brands are majority-video advertisers on Google: ManyPets (70% of its 900 captured Google creatives are video), giffgaff (65%), Gymshark (64%) and Xero (57%). At the other end, 6 of the 145 brands run no video at all — including Center Parcs, a heavy Google advertiser with 736 captured creatives and not one video among them, and Direct Line with 225. By raw volume the biggest YouTube advertisers we track are EE (1,419 video creatives captured), ASOS (1,102) and B&Q (1,015).

The practical point: thirty seconds with the video filter tells you whether a competitor has committed to YouTube at all. Insurance and travel brands that dominate your search auctions may be entirely absent from video, and DTC subscription brands you barely see in search may be spending most of their Google budget there.

2. Video rotates roughly eight times faster than search ads

Longevity is the one free performance signal the Transparency Center gives you, and it means something different per format. Among the ads currently live in our data, the median text ad has been showing for 556 days; the median live video ad for just 65. Only 37% of the 6,573 live video creatives we track have run 180 days or more, against 80% of text ads. Search winners are left running for years; YouTube creative is launched, tested and replaced continuously — our tracked brands launched 1,163 new video creatives in the last 30 days alone.

That churn is what makes the survivors valuable. When a video ad keeps running for months on a channel where the median creative lasts two, somebody is choosing to keep paying for it. The longest-running live video ad we track is a Cult Beauty creative first shown in February 2023 and still live after 1,353 days, with Charlotte Tilbury (1,231 days) and B&Q (1,207) close behind. If you only steal one thing from a rival's YouTube library, steal their oldest still-live video — it's the closest thing to a published control creative you'll get. Our guide to finding competitors' winning ads builds a whole method on this.

3. Sort by date and you can watch launches happen

Because video creative turns over quickly, the video filter is the best place in the whole Transparency Center to spot campaign launches: narrow the time window to the last few weeks and new first-shown dates stand out in a way they never do in a wall of ten thousand near-identical search text ads. A cluster of fresh video creatives usually means a new campaign, a new agency, or a new positioning — worth noticing the week it happens, not the month after. (One caveat: first-shown dates in any third-party dataset, including ours, depend on when capture started — our guide on how accurate ad launch data is explains the honest limits.)

The catch: the 900-creative cap applies to video too

The Transparency Center has an undisclosed retrieval limit we found by testing it in July 2026: for large advertisers it reports a big ad total, then quietly stops paginating at roughly 900 creatives — no error, no warning, the list just ends. Video is usually the least affected format because volumes are lower, which is one reason it's the right place to start with any big advertiser. But it is not immune: EE currently has 778 live video creatives in our data, so for the heaviest YouTube advertisers even the video filter runs close to the ceiling, and scrolling to the end of the grid is not the same as seeing everything. The full findings — including why the cap bites big-box retailers hardest and why slicing by day and format doesn't rescue you — are in our Google Ads Transparency Center guide.

YouTube versus the other platforms' libraries

If you're building a full competitor picture, YouTube is one of four libraries, each with different rules:

Our overview of how to see competitor ads on every platform ties the four together into one workflow.

The honest verdict

There's no YouTube ad library because there doesn't need to be one: the Google Ads Transparency Center's video filter is official, free, and — for all but the very largest advertisers — effectively complete. Its real weaknesses are the ones it shares with every platform library: no spend or performance data, no aggregation, no alerts, no memory of what changed since last week, plus the retrieval cap that quietly truncates the biggest advertisers.

That last set is the gap AdRival closes. We snapshot UK brands' live ads across Google (including YouTube), Meta, TikTok and LinkedIn, AI-qualify every Google, Meta and TikTok creative we capture for offer, hook, urgency and 16 more fields, and flag what's new, what's evergreen and what's on promotion — so "what did my competitor launch on YouTube this month?" is a report, not an afternoon of unlisted watch pages.
