Google Ads Transparency Center Scrapers: A Practical Guide

November 8, 2026

Google's Ads Transparency Center shows the ads an advertiser has run on Google. It is the best free way to see a competitor's Search, Display and YouTube creative. This guide covers what it shows, the official access Google offers, and a routine for tracking ads over time.

What the Transparency Center shows

Google describes it as a "searchable repository of advertisers and the ads they've served" on platforms like Search, Display, Gmail and YouTube. For each advertiser it shows the name, location and the entity that pays for the ads. You can filter by date and targeted location. For ads served in certain regions, it adds targeting information, the total number of recipients and a subject label Google Ads transparency help.

What it does not show for commercial ads: spend, clicks or conversions. For political and election ads, Google points to a separate political advertising report.

Official access

Google's help page says: "Google provides API access to data about ads served in the EEA in the Ads Transparency Center", subject to the Center's terms. For ads outside the EEA, it says Google may give API access to regulators and self-regulatory organizations source. So if your market is the EEA, start with the official route. For other markets there is no public API, and the website is the only official view.

Using the website by hand

1. Search the advertiser by name or by website domain.
2. Pick the region. Results differ by country.
3. Filter by platform (Search, YouTube, and so on) and by format (text, image, video).
4. Open ads to see when they were last shown.

This is fine for one competitor once. It gets slow for 10 competitors every week, and it keeps no history: once an ad ages out, you lose it.

What to log for each ad

A weekly routine

1. Find advertiser ids once. Search each competitor's name and save the id. Domains work too, but one domain can map to several advertisers, such as resellers.
2. Pull ads weekly per competitor, region and platform you care about.
3. Diff against last week. New ads are tests or launches. Ads still running after 8 weeks are probably winners.
4. Open details only for new ads. That keeps cost down.
5. Write a one-page summary: new offers, new landing pages, formats added or dropped.

# Find the advertiser, then list its YouTube video ads in the US
curl "https://scrapeio.com/v1/google/adLibrary/advertisers/search?query=notion&region=US" \
  -H "x-api-key: YOUR_KEY"

curl "https://scrapeio.com/v1/google/company/ads?domain=notion.so&region=US&platform=youtube&format=video" \
  -H "x-api-key: YOUR_KEY"

Reading the results

• Many text ad variants with one landing page: they are testing headlines. Note which wording survives.
• New video ads on YouTube: a brand push, often before a launch.
• New regions: market expansion, a strong signal for planning.
• Ads that stop all at once: a budget cut, a rebrand or a change of agency. Check their site and their other channels.

A note on scraping the site directly

The Transparency Center is a script-heavy web app. Building your own scraper means reverse engineering its internal requests and fixing it when they change. Don't try to get past any challenge or rate limit it shows. If you only need EEA ads, use Google's own API access.

How to do it with ScrapeIO

The Google advertiser search API finds advertisers by name and region for 1 credit. The Google company ads API lists an advertiser's ads by domain or advertiser id, with region, platform, format, topic and date filters; it costs 25 credits a call, so open details only when you need them. The Google ad details API opens one ad by URL for 1 credit.
