In June 2026, Google will update its Limited ad serving policy to cover additional scenarios specifically on Google Search. This adjustment will be gradually implemented and is expected to conclude by 2028.
The new policy stipulates that Google may restrict ad impressions for unqualified advertisers in situations likely to result in negative user experiences. Advertisers’ qualifications will heavily consider user reports regarding their content and behavior. Best practices for maintaining ad visibility include clear branding and compliant ad copy.
