Google has spent the past month quietly expanding what advertisers can do inside AI Mode — and the latest updates are the most significant since the format launched. Travel advertisers now have access to contextual placements inside AI Mode responses, and every advertiser running Search campaigns has been given access to AI Max text guidelines. The data on performance is starting to come in, and the numbers are not what most advertisers expected.
Travel joins shopping inside AI Mode
Google first introduced sponsored product recommendations inside AI Mode in February 2026, placing ads within AI-generated shopping responses. The April expansion brings the same format to travel queries. Hotels, airlines, and travel advertisers can now appear contextually within conversational results when users ask AI Mode for destination recommendations, itinerary planning, or accommodation options.
This is a significant category unlock. Travel is one of the highest-value verticals in digital advertising, with average CPCs far above the platform mean. The fact that Google is prioritising travel as the second vertical after shopping signals that the AI Mode ad product is being built out category by category — services and B2B placements are expected to follow in H2 2026.
AI Max text guidelines now available to all
The second major change affects every Search advertiser. AI Max text guidelines — previously in limited beta — are now generally available. This feature gives advertisers direct control over how Google’s AI generates and customises ad copy within AI-powered formats. Advertisers can specify tone constraints, must-include phrases, and content restrictions that carry through into AI-generated ad variations.
For brand-sensitive advertisers and regulated industries, this is a long-requested capability. AI-generated ad copy has been a source of compliance anxiety since AI Max launched; the text guidelines feature reduces that risk substantially.
The performance data: higher engagement, higher cost
Early performance data from AI Mode ad placements is now available at scale, and the results are nuanced. Ads appearing inside AI Mode generate 18% higher engagement compared to equivalent standard Search placements. The cost is real, though: CPCs inside AI Mode run approximately 35% above standard Search equivalents for the same keywords.
Ads are currently appearing in 25.5% of AI Mode sessions — a coverage rate that has remained stable since the format expanded in February. For advertisers, this means AI Mode is not yet a replacement for standard Search but a complement: higher intent, higher cost, lower volume.
What this means for GEA strategy
The travel expansion and AI Max rollout together confirm the direction of travel for Google’s AI advertising roadmap. More verticals will follow. The tools for controlling AI-generated creative are maturing. For B2B advertisers — GEAFirst’s core audience — the relevant question is not whether to be in AI Mode now, but how to build the creative and bidding infrastructure so that when B2B placements open, you are not starting from zero.
The brands that are running AI Mode campaigns today, learning what resonates in a conversational context, are building knowledge that will not transfer from a competitor’s playbook. GEA advantage, like most first-mover advantages in digital, compounds.
