Generative search ads powered by Gemini are no longer a roadmap item. They're live in testing — embedded inside AI-generated answers, not beside them. Here's what every paid search advertiser needs to understand right now.

AI Mode Sessions End Without a Click
For over two decades, the structure of a Google search results page remained essentially unchanged: a query goes in, a ranked list of blue links comes out, and ads occupy the premium real estate at the top. Advertisers bid on keywords, write static copy, and optimize for clicks. That model built a trillion-dollar business.
Google Marketing Live 2026, held on May 20th, made something clear: that model is being retired — not gradually, but structurally. The company announced a new generation of Gemini-powered ad formats designed specifically for AI Mode, Google's conversational search experience. The ads are no longer placed beside AI-generated answers. They are woven into them.
"Now, you can ask Google anything — so the best ads must be answers."

AI Mode Is No Longer a Beta Product
What started as an experimental tab in Google Search has become its most significant growth story. AI Mode has surpassed one billion monthly users, with queries more than doubling every quarter since launch. At Google I/O in May 2026, the company announced it would upgrade AI Mode to Gemini 3.5 Flash as the default model globally — and that generative UI capabilities, including real-time custom layouts and interactive simulations, would roll out to all Search users this summer at no charge.
The commercial implications follow the usage. As AI Mode reshapes how people search, Google's advertising business must reshape how ads appear. The company acknowledged this directly at GML 2026, framing the new ad formats not as an experiment but as the beginning of a mandatory transition for advertisers.
Four New Ad Formats — All Gemini-Powered
Google introduced four distinct formats at GML 2026. Each targets a different moment in the user journey and requires a different approach to creative and measurement.
Format 01
Conversational Discovery Ads
Gemini generates ad creative in real-time, tailored to the user's exact query inside AI Mode. Someone searching for ways to make their home smell like a spa might see dynamically generated copy highlighting specific product features relevant to that intent — not a pre-written ad pulled from a campaign template.
Format 02
Highlighted Answers
When AI Mode returns a list-style response — say, the best running shoes for flat feet — eligible ads can appear as a recommendation inside that list. Placement is determined by relevance, not bid alone. Advertisers cannot directly target this placement; Gemini decides what fits the moment.
Format 03
AI-Powered Shopping Ads
Built for high-consideration purchases like TVs, appliances, and software. Gemini pulls your product feed and writes a custom explainer per query — not per campaign — describing why this specific product fits this specific shopper's stated needs at this specific moment.
Format 04
Business Agent for Leads
Instead of clicking an ad and landing on a static form, users interact with a Gemini-powered chat agent trained on the advertiser's website — directly inside the search results page. The AI qualifies the user, answers their questions, and auto-fills the lead form before a click ever happens.
Conversational Discovery Ads and Highlighted Answers are currently in testing in the U.S. on mobile and desktop. AI-powered Shopping Ads are expected to roll out later in 2026. Business Agent for Leads has entered open beta for U.S. advertisers.
The 92% Problem: Where Did the Clicks Go?
The single most consequential figure from this shift is not the user count or the ad format roster. It is this: between 92% and 94% of AI Mode sessions currently end without a click to an external website.
That is not a rounding error. It means the high-intent search traffic that historically flowed to landing pages — the traffic advertisers built entire campaign structures to capture — is increasingly being resolved inside Google itself. Users are getting answers, forming opinions, and in many cases making decisions without ever leaving the SERP.
For brands that are not present within the AI answer layer, the effect is invisible but significant. They are not losing click-through rate. They are losing the moment. And if they are not cited in the AI-generated response, they may not exist in the user's consideration set at all.
This is why Google's framing at GML 2026 was pointed. The new ad formats are not additions to the existing funnel — they are replacements for the entry point of it.
Dynamic Search Ads Are Being Retired
The shift to generative ad formats also marks the end of Dynamic Search Ads as a standalone product. Google announced that DSA campaigns will be sunset and auto-upgraded to AI Max beginning in February 2027, with campaigns using Automatically Created Assets and campaign-level broad match beginning auto-upgrade in September 2026.
AI Max — which moved out of beta at GML 2026 — carries the same catch-all traffic expansion logic as DSA, but replaces landing page scraping with broader real-time intent signals. Early data from Google shows AI Max for Search campaigns delivering an average of 7% more conversions or conversion value at a similar CPA or ROAS when using the full feature suite.
Advertisers who have not yet voluntarily migrated are encouraged to do so now, while there is still time to configure brand controls, location controls, and text guidelines before the automatic transition begins.
What This Means for Advertisers and SEOs
The operational changes required are specific. The new formats do not replace Performance Max or standard Search campaigns — they extend the surface area where a brand can appear. But they require fundamentally different inputs.
Gemini generates Conversational Discovery Ads and AI Shopping Ads from existing creative assets. Sparse, generic assets produce sparse, generic AI-generated ads. Advertisers need variety: lifestyle imagery, specific use-case headlines, benefit-led descriptions that give the model enough material to work with across a wide range of query intents.
On the organic side, the same structural shift is redefining what SEO visibility means in 2026. With AI Overviews appearing on an estimated 48% of tracked queries — up from 31% a year prior — appearing inside the answer layer is where an increasing share of organic visibility now happens. This is the territory of Generative Engine Optimization (GEO): structuring content so that AI systems can accurately summarize, cite, and surface it in generated answers.
"The brands that arrive prepared — with strong creative, rich data, and solid attribution infrastructure — will have a meaningful edge."
— EasyInsights, May 2026
Attribution is the third leg. With the majority of AI Mode sessions ending without a click, traditional last-click and even multi-touch models will increasingly misrepresent how users are discovering and evaluating brands. First-party data infrastructure, enhanced conversions, and offline conversion imports need to be in place before AI Mode reporting becomes a standard part of campaign dashboards.
// Advertiser Action Items
- Audit your creative asset library — variety and specificity determine what Gemini has to work with when generating conversational ads.
- Deepen product feed data in Google Merchant Center beyond required fields — richer inputs produce more relevant AI-generated shopping explainers.
- Implement Enhanced Conversions and validate first-party data pipelines before AI Mode becomes a standard reporting surface.
- Begin voluntary migration from Dynamic Search Ads to AI Max before the February 2027 auto-upgrade deadline.
- Build a GEO content strategy — structure pages to answer specific questions early and clearly so they are citable inside AI Mode responses.
- Document current attribution models and performance baselines now, as a reference point for measuring what changes when AI Mode ad formats scale.
The Bottom Line
Google has been telegraphing this shift for years — through AI Overviews, through the expansion of Gemini into Search, through the quiet erosion of the traditional blue-link SERP. What Google Marketing Live 2026 confirmed is that the transition is no longer incremental. The entire advertising surface is being rebuilt around conversational, generative, intent-matched experiences.
The keyword-first, static-creative playbook is not disappearing tomorrow. But it is shrinking — and the AI-native interfaces designed to replace it are already in testing.
