Short answer
The Google Ads Transparency Center is Google's searchable library of ads from verified advertisers, covering platforms such as Search, Display, Gmail and YouTube. You search by advertiser or website name at adstransparency.google.com, then filter by region and date to see the ads a business has run, each ad's format and the last date it ran. Google announced the new version on March 29, 2023.
How to use the Google Ads Transparency Center guide
- Type a competitor's website into the box at the top of this page.
- Click the button to open Google's Ads Transparency Center. The domain is copied to your clipboard as it opens.
- Paste the domain into the search box on Google's page and run the search.
- Set the region to the country you care about, pick a date range, then look through the ads.
- Or click the Competitor Ads Finder button to see that website's ads listed with their dates.
What is the Google Ads Transparency Center?
Google describes the Ads Transparency Center as "a searchable repository of advertisers and the ads they've served on Google platforms like Search, Display, Gmail, and YouTube" (Google's ads transparency page). It is free to search and the first place to look when you want to know what another business is advertising.
When Google announced the new version on March 29, 2023, it called it "a searchable hub of all ads served from verified advertisers" (Google's launch post). The word verified matters: the library is built around advertisers that have completed Google's advertiser verification.
How do you search the Ads Transparency Center?
- Open adstransparency.google.com in your browser. You can also reach it from the three-dot menu in My Ad Center.
- Type the advertiser's name or website into the search box. Google lets you search by either one (My Ad Center Help).
- Set the region filter to the country where the business advertises, such as the United States.
- Set the date filter to the period you want to review.
- Look through the results: the ads the business has run, the format of each one and the last date it ran.
Search by website when you are not sure of the company's legal name. Google shows the verified name or organization's name, which can differ from the brand on the sign or the truck.
The box at the top of this page saves a step: it copies the domain to your clipboard and opens Google's site, so you only paste and search. Paid Pilot is not affiliated with Google, and the button simply opens Google's own page.
What can you see about an advertiser?
Google's own pages list the details below. Anything missing from the list, such as budgets, bids, keywords or clicks, is not something Google says you will find.
| What you can see | Google source |
|---|---|
| The ads an advertiser has run | Launch post |
| Which ads were shown in a certain region | Launch post |
| The last date an ad ran, and its format | Launch post |
| Name or organization's name and location | Advertiser verification |
| Name change history | Advertiser verification |
| Ad creatives, and the dates and locations ads served | Advertiser verification |
| Ads removed or accounts suspended for legal or policy reasons | Advertiser verification |
| Organization contact information | Advertiser verification |
| Targeting information and recipient counts, for ads in the European Economic Area | Ads transparency page |
The verification rows come from Google's advertiser verification policy, which lists what is shown publicly about verified advertisers. For US ads, treat the Transparency Center as a record of what ran, where and when, not of what it cost. For typical costs, read how much Google Ads costs in 2026.
Why can't you find a business in the Transparency Center?
- It is listed under another name. Search the website as well as the brand, and try the legal company name if you know it.
- The region or dates are too narrow. Widen the date range and check that the region matches where the business advertises.
- It has not finished verification. The center is built around verified advertisers, and Google says all advertisers will eventually be required to complete advertiser verification.
- It does not advertise on Google. After the checks above, an empty result is a reasonable sign of that, though not proof.
For a quick verdict on any website, including the last date an ad was shown, use the Google Ads Activity Checker.
Tips for researching competitors in the Transparency Center
- Note what each competitor promises: price, speed, guarantees, service area. The claims everyone repeats show you where you need to say something different.
- Check the last date shown before you react. An ad from last week tells you more about a current offer than one from last year.
- Do not copy wording or images. If you use a competitor's trademark in your ad text and the owner complains, Google may restrict its use (trademarks policy).
- Look yourself up. Search your own website to see which name Google shows for your business and which of your ads appear.
- To list every ad a website has run, with first and last shown dates, use the Competitor Ads Finder. For a spreadsheet copy, use the Advertiser Research Exporter. Both fetch live data through a data provider, which costs money, so free lookups are limited each month and results are cached for a few days.
