- Definition
- A new advertiser, in brand monitoring, is a domain seen showing an ad on your monitored searches for the first time.
In plain words
A new advertiser is a domain your monitoring has not seen before on your searches. It is new to your record, not necessarily new to advertising.
Saying "newly observed" keeps that difference clear.
Why it matters for brand and paid search teams
New names on a brand search are the first signal most teams want: a competitor starting a push, an affiliate breaking the rules, an unknown seller or a lookalike domain.
Getting that signal quickly, with the ad and its context attached, lets the right person review it before it becomes a pattern.
How it works
Advertisers can target specific locations, devices and times, so a domain may have run ads before in places or at times you did not check. Google's location targeting also includes people who show interest in a location, not only those inside it.
Google's Ads Transparency Center lets anyone search ads by advertiser or website name and filter by date and location, which helps research an unfamiliar domain. It shows ads an advertiser has run, not what appeared on a particular search.
How "new" is defined also depends on your record. The more searches, places and devices you check, and the longer your history, the more meaningful a first sighting becomes.
Example
On Tuesday, trailpicks.example appears for the first time on northstar hiking boots on mobile in Seattle. The alert includes the ad text, which compares three boot brands, and a destination URL with a tracking parameter.
The team looks up the domain, finds it is a review site in the affiliate program, and labels it as an affiliate.
Fictional brands and domains, for illustration only.
Common mistakes and misconceptions
A new advertiser just started advertising. It is new to your observations. It may have run ads elsewhere or earlier.
Every new advertiser needs escalation. Start with the ad text, destination and public information, then label it. Most turn out to be ordinary.
No new advertiser alerts means nobody is advertising. The first check sets a baseline, and advertisers seen there never trigger this alert. Open the reports to see everyone who keeps appearing.
How to monitor it in Ads Lighthouse
A New advertiser observed alert fires when a domain you do not own appears for the first time in a project. The first check on each search engine is the baseline and does not alert.
An Advertiser observed again alert covers domains that return after at least 30 days without being seen while your checks kept running. Alerts go by email, Slack or webhook, and each links to the saved ads behind it.
Frequently asked questions
Why did I not get alerts after my first check?
The first check on each search engine is the baseline. Advertisers seen there do not trigger New advertiser observed; from the next check on, unseen domains do.
Can I limit alerts to one country or device?
Yes. An alert rule can be limited to one search engine, one device or a country code such as US.
Does an alert mean the advertiser broke a rule?
No. It reports what a check observed. Open the evidence and review it before you act.
