How to use the Google Ads Transparency Center to find winning ads (2026 guide)

The Google Ads Transparency Center is Google's public ad library. Type in a competitor's name or website and you see the ads they have run on Google Search, YouTube, Shopping, Maps and Google Play, with no login and no Google Ads account. It is the fastest way to answer "what is this brand running on Google right now?"

Like the Meta Ad Library, it shows you everything and ranks nothing. There is no spend, no click-through rate and no "best ads" sort. This guide covers how to search it, which filters are worth your time, and how to read the dates on each ad so the proven ones stand out from the tests.

How to search the Google Ads Transparency Center

Go to adstransparency.google.com. The search box takes two kinds of input, and the difference matters:

An advertiser name. This is the verified name Google holds for the account, which is often the legal entity rather than the brand. "Acme Skincare" may advertise as "Acme Brands Holdings LLC".
A website. Type the domain, such as example.com, and you get the advertisers tied to that site. This is the better starting point when you only know the brand, because one brand can advertise under more than one verified name, for example a regional company or an agency account.

Try the website first. If the results look thin, search the name too and compare. Click an advertiser and you land on their page, with every ad in a grid and the filters across the top.

The filters that actually matter

Region. Pick the country you sell in. A brand's UK ads and US ads can be completely different, and the default view mixes them.
Date range. Presets such as the last 7 or 30 days, a custom range, or "Anytime". Use the last 30 days to see what is live now, and "Anytime" to see everything the brand has tried.
Platform. Search, YouTube, Shopping, Maps or Play. This tells you where a competitor puts its effort. A brand with hundreds of YouTube ads and a handful of search ads is buying attention, not intent.
Format. Text, image or video. Text ads are the search ads, image ads are mostly display and Shopping, and video is YouTube.

Open any ad to see it full size, the advertiser's verified name and location, and who paid for it.

What you will not find, and what the EU view adds

For ordinary commercial ads there are no performance numbers at all: no spend, no impressions, no clicks. Google publishes spend and impression ranges only for election ads, in its separate political ads report.

Ads shown in the European Economic Area are the exception. For those, Google's own help pages say the Transparency Center adds how the ad was targeted, the total number of people it reached, and a subject label for the ad. If you sell in Europe, set the region to an EU country and you get a real reach number next to each ad. Meta's library does the same for ads it delivers in the EU; outside Europe, neither shows reach for ordinary commercial ads.

Reading the dates: the free winner signal

Every ad in the Transparency Center has a first shown and a last shown date. Together they are the closest thing Google gives you to a performance metric.

Advertisers stop paying for ads that lose money, usually within days. So an ad first shown in March and last shown yesterday has survived six months of someone checking the numbers and deciding to keep it. That is a proven ad. One first shown last week is a test: it might be great, but nobody knows yet, including the advertiser. We wrote a whole post on why run length is the best free signal, and it holds on Google just as it does on Meta.

Two things to keep in mind. A last shown date of yesterday or today means the ad is still running. And on search ads, a long run means the offer and the landing page work, because the text of a search ad changes with the query it matches. Look at where the ad sends people, not only at the headline you happen to see.

A 20 minute competitor pass

Search three competitors by website, set the region to your market and the date to the last 30 days.
Filter to video. Note which of them run YouTube at all, and which videos have been live longest.
Filter to text. Open the long-running search ads and write down the promise in each headline and the page it links to.
Switch the date to "Anytime" on the strongest competitor and look at what they stopped running. Those are the angles that did not work for them.
Put the long-runners next to each other. The angle two competitors both keep paying for is the one to test first.

Doing it without the clicking

Hermoso runs your marketing on autopilot, and researching what already works is one part of that. Its Ad Spy pulls an advertiser's Google ads by website, with the format, the creative and the first and last shown dates for each, next to the same brand's Meta and LinkedIn ads, and ranks them by how long they have run. From Claude, ChatGPT or Cursor you can just ask "what is example.com running on YouTube?" and get the list back. When you find an ad worth learning from, Hermoso can make your own version of it for your product, ready to run. The competitor ad research guide covers the whole routine across every library.

Questions people ask

Is the Google Ads Transparency Center free?

Yes. It is a public site at adstransparency.google.com. You do not need a Google Ads account or a login to search it.

Can I see how much a competitor spends on Google Ads?

Not for ordinary commercial ads. Google publishes spend and impression ranges only for election ads. For ads shown in the European Economic Area it adds the number of people reached and the targeting, but not spend.

Why can't I find a brand by its name?

The Transparency Center lists the verified advertiser name, which is often the company's legal name rather than the brand. Search by the brand's website instead, which returns the advertisers tied to that domain.

How do I tell which Google ads are working?

Look at the first shown and last shown dates. An ad that has been running for months and was last shown yesterday is one the advertiser keeps paying for, which is the strongest free signal that it makes money.

Does the Transparency Center show YouTube ads?

Yes. Filter an advertiser's page by platform and choose YouTube, or filter by format and choose video, to see their YouTube ads.
