Limited Ad Serving
Limited Ad Serving is a Google Ads policy that restricts ad delivery for advertisers who are unfamiliar to Google or have not yet established a track record of trustworthy behavior on the platform. When triggered, Google limits the impression volume and reach of the advertiser's campaigns — ads may show less frequently, in lower positions, or to a narrower audience — until the advertiser accumulates sufficient positive user interaction history and platform tenure. The policy was introduced to combat a surge in ad scams, fraudulent advertisers, and bad actors who create new accounts to serve deceptive ads before they can be detected and suspended. Legitimate advertisers who are new to Google Ads or who launch campaigns in previously unused verticals or geographies may encounter Limited Ad Serving during an initial ramp-up period, typically lasting days to a few weeks. The mechanism is automatic and not appealable — advertisers cannot request expedited removal. Mitigation strategies include verifying the advertiser identity through Google's advertiser verification program, building a positive account history with compliant campaigns before scaling aggressive spend, and avoiding abrupt changes in ad content, landing pages, or targeting that could signal account instability to Google's risk models. Limited Ad Serving is distinct from ad disapprovals (policy violations) and account suspensions — it is a throttling mechanism, not a punitive action.
