Google Ads Advertiser Check

Paste a list of company domains and get one row per domain telling you whether that company is running Google Ads, who the advertisers behind the domain are, how big the activity is and how recent it is. Built for lead lists and competitor lists: thousands of domains in, a clean table out.

Data comes from the public Google Ads Transparency Center. No login, no cookies, no browser.

Why this Actor

• One row per domain. Other tools return one row per ad or per advertiser, so a 1,000-domain list turns into tens of thousands of rows. Here it stays 1,000 rows.
• A verdict, not just "yes". A domain can have ads pointing to it that were paid for by someone else (resellers, affiliates, agencies, random people). The verdict tells you whether an advertiser matching the domain name was found, whether one advertiser dominates, or whether it is a mixed bag. The advertisers behind the verdict are listed so you can check.
• Pay only for results. You are charged once per domain that returns a row. Domains that fail are listed by name and cost $0.
• Fast and lightweight. ~0.5 seconds per domain in standard mode (300 domains in under 3 minutes).
• Shared platforms flagged. Domains like instagram.com or linktr.ee attract hundreds of unrelated advertisers; isSharedPlatform marks them so they do not pollute a lead list.
• No personal names dumped. Only advertisers that match the domain or hold a meaningful share of the sample are named. Small or one-off advertisers (often private individuals) are counted, not listed.

advertiserCount	Distinct advertisers in the sample.
otherAdvertisers	Advertisers in the sample that are not listed by name.
adsEstimateLow / High	Google's own estimate of the total number of ads pointing to this domain (shown as a range).
latestAdDate	Most recent "last shown" date in the sample.
formatMix	Text / image / video counts in the sample.
isSharedPlatform	true when 25 or more distinct advertisers appear in the sample.
last30Days, channels	Only with detailed: true. Google's estimated ranges for ads shown in the last 30 days and per channel.

Verdicts

Verdict	Meaning
NAME_MATCH	At least one advertiser's name matches the domain. Strong signal the company itself advertises.
SINGLE_ADVERTISER	No name match, but one or two advertisers hold ≥ 90 % of the ads. Often a parent company or agency (e.g. slack.com → Salesforce, Inc.). Check topAdvertisers.
MIXED	Several unrelated advertisers. The domain owner may not be advertising at all.
LOW_VOLUME	Fewer than 5 ads found; too little to judge.
NO_ADS	No ads point to this domain.

Pricing

You pay a flat fee per domain that returns a result. Failed domains are free and are listed in the run status message. detailed mode costs the same per row.

Good to know

• Estimates are Google's rounded ranges, not exact counts. Use them to compare and rank, not as exact figures.
• The 100-ad sample is the most recently shown ads. For domains with tens of thousands of ads the format mix and advertiser list describe recent activity, not all history.
• Name matching is deliberately conservative. A parent company or an agency advertising on behalf of a brand will show as SINGLE_ADVERTISER, not NAME_MATCH. That is why the advertiser names are included.
• Region filtering follows Google's own region filter, which applies to ads shown after September 2023.

FAQ

Is this an official Google API? No. It reads the public Ads Transparency Center the same way a browser does. If Google changes the page, the Actor is updated.

What happens when Google rate-limits? The Actor rotates IPs and retries up to 6 times. A domain that still fails is reported by name and is not charged.

Can I schedule it? Yes. Use Apify Schedules to re-check a list weekly and compare latestAdDate and last30Days over time.
