Google's check of who an advertiser is, as a company or a person, which supplies the name and country its ads disclose.
Google asks advertisers to verify their identity, as an organisation or as a person depending on the account's payments profile. Once verified, the advertiser's ads disclose its name and location in About this advertiser and in the Ads Transparency Center, where its page carries the line “Advertiser has verified their identity”. Where someone else pays for the ads, the payer's name can show too.
Google selects accounts for verification for several reasons, and one it lists is running ads on brand-related searches. So an advertiser appearing on your name is likely to have been asked to verify, and likely to show a legal name you can look up.
- A verified name is a legal name, often a company you won't recognise from the ad.
- One legal name can sit under several advertiser ids, and a new id doesn't mean a new business.
- Submitting false information in verification falls under Google's Circumventing systems policy.
Treat the name as a strong clue rather than a full answer. Your network can say whether it matches any publisher on your programme.
Google's own help and policy pages first.
