How to use Google's Ads Transparency Center for your brandHow to use Google's Ads Transparency Center for your brand

Yourbrand's paid-search lead types yourbrand.example into the Ads Transparency Center, sets the region to the United Kingdom, and gets four advertisers. One is Yourbrand Ltd. One is the agency's own company. The other two she's never heard of, and one of them has an ad showing yourbrand.example, last shown on Sunday.

That's the Transparency Center doing its job: it's Google's public register of who advertises what. This guide goes through how to search it, how to read each page, what each field means, and the longer list of things it leaves out.

What it is

Google launched the current Ads Transparency Center on 29 March 2023 as a searchable library of ads from verified advertisers. It covers Search, YouTube, Google Play, Maps and Shopping, keeps an ad for a year after it was last shown, and needs no Google Ads account. The British version of the site spells it Centre. Its own FAQ says it also includes advertisers who haven't verified, but only in Europe and Türkiye, so an unverified advertiser running only in the UK may not be there at all.

The names come from advertiser verification. A verified advertiser shows its legal name, where it's based and the line “Advertiser has verified their identity”. Where the account is paid for by someone else, the payer's name appears too. A person who verifies shows their own name and country, not an address. Running ads on brand-related searches is one of the reasons Google gives for asking an advertiser to verify.

It's the same identity Google shows in About this advertiser on the results page. The difference is that the Transparency Center doesn't depend on where you search from, which device you use or what hour it is. An advertiser that only runs in Leeds after 20:00 is still listed.

The search box and the filters

There's one search box, for an advertiser's name or a website. There's no search by keyword or by ad text. Then four filters:

• Region. The button reads “Ads in” and a country. It defaults to the country you're browsing from, not to the UK, so set United Kingdom yourself, or Anywhere to see every region.
• Date. Any time by default, with Today, Yesterday, Last 7 days, Last 30 days and Custom. Any time goes back to 31 May 2018. Dates follow Pacific Time, eight hours behind London for most of the year.
• Platform. Google Search, YouTube, Google Play, Google Maps or Google Shopping.
• Format. Text, Image or Video. Search ads are text.

Two searches: your address and your name

Your web address finds the advertiser accounts whose ads point to it. On Search, an ad's display URL takes its domain from the final URL, the page the click lands on, so an ad showing yourbrand.example leads to your shop. That list should be you, your agency, and any partner you've allowed to send ad clicks straight to your site. Anyone else is worth a question, because direct linking is something most programme terms rule out without permission.

Your brand name finds advertisers by name, which mostly means you and anyone with a similar name. It won't find a voucher site advertising its page about you, because that ad points to the voucher site. For those, your own searches, Ad Preview and Auction insights are the tools, and the guide to who's bidding covers them.

Reading an advertiser's page

• The name, the Legal name and Based in, with the verification line.
• The advertiser id in the page's address: AR followed by 20 digits. It's the firmest way to refer to the advertiser, so copy it into every note and email.
• An approximate count of its ads, and the ads themselves, with the same four filters.

Open an ad and you get a picture of it as it rendered, up to five variations, its Format, the region it was Shown in and the date it was Last shown. It's a still image: you can't click through to the landing page, and Google says that's permanent. Ads appear 48 to 72 hours after they're shown, so last night's ad may not be there yet.

Putting dates on a change

Last shown dates are enough to date a handover between accounts. Imagine a publisher is removed from your programme on Monday 12 October, and on Thursday 15 October the same headline appears under another advertiser. Note the first advertiser's latest Last shown date, then set a custom date range on the second to find its earliest ads. One record stops, the other starts: a three-day gap you can write down and send.

Two of four were yours. That's typical, and it's why matching comes before asking.

How to search it, step by step

1. Open the Ads Transparency Center and search for your web address, yourbrand.example. A banner says how many advertiser accounts have ads pointing to it.
2. Set the region to United Kingdom, the platform to Google Search and the date to Any time for the first look.
3. List every advertiser: the name, the legal name, where it's based, the approximate number of ads and the AR id from its page's address.
4. Mark the ones you know: your own accounts, your agency's, your group companies and approved partners. Ask your agency for the name of every account it runs for you.
5. Open each advertiser you don't recognise. Read its ads, note the headline and the Last shown date of each, and take a screenshot.
6. Search your brand name too, and note any advertiser that isn't you.
7. For an advertiser that's new since your last look, set a custom date range to find its earliest ads, and compare with the last ads of any account that stopped around then.
8. Repeat every week, or keep an outside record that does. A new AR id on your address is the thing to notice.

Names are a loose key

One legal name can sit under several advertiser ids, Google's own included, so a new id doesn't mean a new business. Accounts billed to one payments profile under a manager account can all show the same name. A shared name doesn't prove the same business, and a new name doesn't prove a different one. The AR id and the dates are firmer than the name.

Your network's report names publishers, and the Transparency Center names advertisers. They can both be accurate and still differ: a publisher's ads may run from an agency's account, a parent company's or a sub-publisher's. Only your network, and any sub-network in between, can join the two.

The ordinary explanations

• Your agency, running a second account, a test or an old campaign under its own company name.
• Another company in your group, or another team, with its own Google Ads account.
• A shopping or comparison partner whose ads send clicks to your product pages with your agreement.
• A partner you allowed to link straight to your site, perhaps before your time.
• An account that ran a campaign for you once and has no recent ads: check the Last shown dates before asking.
• An advertiser that has nothing to do with you at all, with a name like yours. Check its ads point to your address before going further.

If an ad does look outside your terms, the Transparency Center has its own route: open the ad and use Report this ad. The guide to reporting an ad covers what to put in it.
