AI Max rewrites over a quarter of exact match impressions, smec data shows
Smarter Ecommerce analysed 383 million Search impressions with AI Max activated. Over 25% of exact match keyword impressions were served on AI Max's expanded matching rather than the keyword as written.

Why it matters for advertisers
For you, this means exact match is not exact once AI Max is on, so monitor search term reports closely.
