Google updates Lookalike audiences in Demand Gen to AI suggestion model from March 2026
1 days ago
Starting March 2026, Google will change Lookalike segments in Demand Gen campaigns from strict similarity-based targeting to an AI-driven suggestion model that can expand beyond the selected list to optimize conversions. Advertisers can still request legacy Lookalike targeting. This change aims to improve performance by allowing more automation, similar to Meta's AI targeting approach, though it may reduce control.
