What Is the Google Ads Transparency Center?

Google launched this official tool in 2023 to publicly show "who is running what ads."

URL: https://adstransparency.google.com/

It covers ads delivered across Google's entire network — Search, YouTube, Discover, Display, and more. You can filter by region (Japan, US, etc.).

Purpose

As Google puts it:

"We're committed to ensuring ad transparency to help build a safe and open internet."

In short, it's a mechanism that lets users see where the ads shown to them come from and verify the advertiser's identity.

I Actually Searched — Here's What Happened (Amazon Example)

Here's a reproduction of my actual search for "Amazon."

Step 1: Enter a company name in the search bar on the top page

The top page has a prominent search bar that reads: "Search by advertiser name or website to find ads they've previously run." I typed in Amazon.

Step 2: Suggestions appear

As you type, suggestions come up for both advertisers and websites:

You can see the "Verified" badge next to each entry.

Step 3: Click an advertiser to see their full ad list

Clicking "Amazon Japan G.K." opens the advertiser detail page.

Information displayed:

• Official name: Amazon Japan G.K.
• Location: Japan
• Identity verification: Completed
• ~800,000 ads

And then, a scrollable list of every ad creative they've run. For example:

• "Hats · Caps · Large Size · UV Cut 100%…"
• "Disaster Prevention Backpack [Supervised by Disaster Prevention Specialist]…"
• "Water-Cooled Vest · Physical Cooling Wear · Heatstroke Prevention…"
• "Captain Stag Cooler Box…"
• "Binoculars · For Concerts · High Magnification 15x…"

You can see the product name, ad copy, and a link to "Amazon Official Site" — all as actual ads, one by one.
