Google's Gemini Ad Formats Are Live in Search: What Advertisers Need to Know

At Google Marketing Live 2026, Google unveiled a new generation of Gemini-powered ad formats built for AI Mode and the classic search results page — and as of mid-July they are no longer just slides. Conversational Discovery ads and Highlighted Answers are now in live testing with US advertisers on mobile and desktop, while a Business Agent for Leads has opened in beta and AI-powered Shopping ads are queued for later this year.
This is the moment the "agentic" advertising Google has been previewing starts touching real campaigns. If you run paid search, the change is bigger than a new ad unit: Gemini now writes creative on the fly, answers questions inside the ad, and in some formats holds a conversation with the buyer before they ever reach your site. Here is what each format actually does, how it changes campaign work, and the concrete steps to get ready.
What Google actually announced
Google introduced four distinct ad experiences for AI-powered Search. They are related but behave very differently, so it helps to separate them:
- Conversational Discovery ads. Instead of a fixed headline-and-description block, Gemini builds creative tailored to the specific question a person asks, surfacing the features most relevant to that query. The same product can be presented dozens of different ways depending on intent.
- Highlighted Answers. A sponsored placement woven into the AI-generated answer itself, where a brand's response is elevated as part of the conversational result rather than sitting in a separate ad slot at the top or bottom.
- Business Agent for Leads. An AI chat experience embedded directly inside lead-generation ads. Rather than filling out a static form, the user talks to a Gemini agent trained on the advertiser's website, which answers questions and qualifies the lead in-line. This launched in open beta for US advertisers.
- AI-powered Shopping ads. Product ads that adapt to conversational shopping queries in AI Mode, expected to roll out to US advertisers later in 2026.
The through-line is that Gemini is no longer just optimizing bids behind the scenes — it is authoring the ad and, in the case of Business Agent, conducting the sales conversation. That is a meaningful shift from the disclosure-and-labeling change we covered when Google began flagging which ads are made with AI. There, AI wrote the creative and a label acknowledged it. Here, AI is an active participant in the ad experience itself.
How the four formats compare
Each format targets a different stage of the buying journey and hands a different amount of control to Gemini. This table is the quickest way to see where each one fits.
| Format | Where it appears | What Gemini does | Status (US) |
|---|---|---|---|
| Conversational Discovery ads | AI Mode & Search | Generates query-specific creative and feature highlights | In testing, mobile & desktop |
| Highlighted Answers | Inside the AI answer | Elevates a brand response within the generated result | In testing |
| Business Agent for Leads | Lead-gen ads | Runs a live chat that qualifies leads from your site data | Open beta |
| AI-powered Shopping ads | AI Mode shopping queries | Adapts product ads to conversational intent | Rolling out later in 2026 |
Why this matters for advertisers
For a decade, paid search rewarded advertisers who could engineer the perfect static asset: a tight headline, a sharp description, the right keyword match type. Gemini-authored formats quietly dismantle that playbook. When the model writes creative per query, your headline stops being a fixed lever and becomes an input the machine reworks. The competitive edge moves upstream — to the quality of the product information, feeds and brand assets Gemini draws from.
The Business Agent shift is the most consequential. A conversational lead agent trained on your website means your site content is now your sales script. If your pages are thin, contradictory or out of date, the agent will faithfully relay that to prospects. Conversely, well-structured, factual pages give the agent good material to convert on. The line between SEO content and paid creative is blurring — the same clear, entity-rich pages that help you get cited in AI search now also feed the ad agent that talks to your buyers.
There is also a cost dimension. As AI surfaces absorb more of the results page and Gemini takes on more of the optimization, advertisers have less granular control and, historically, less control has meant Google captures more of the value. We flagged this trend when Google Ads costs climbed through 2026; agentic formats are likely to extend it, because performance now depends on assets and data the advertiser supplies rather than on manual bid and keyword tuning.
What to do now: a five-step readiness plan
1. Audit the data Gemini will draw from
Conversational Discovery ads and AI Shopping ads build creative from your product feeds, business information and landing pages. Treat those as first-class ad assets, not afterthoughts. Make sure product titles, attributes and descriptions are complete and accurate, and that your feed is free of the gaps and stale prices that will now show up directly inside generated ads.
2. Rewrite key pages for the Business Agent
If you plan to test Business Agent for Leads, read your top landing pages as though a customer-facing chatbot will quote them verbatim — because it will. Add clear answers to the questions prospects actually ask: pricing logic, eligibility, timelines, what happens after they submit. Ambiguity that a human sales rep would smooth over becomes a wrong answer from the agent.
3. Keep a human-quality creative baseline
Gemini generates within the guardrails of the assets and brand guidelines you give it. Supply strong headlines, real imagery and a clear value proposition as raw material, and set brand-safety rules explicitly. The model composes; it does not invent your positioning. Weak inputs produce generic conversational ads that blend into the answer and win nothing.
4. Instrument measurement before you scale
Conversational and in-answer placements do not map cleanly onto the old impression-and-click model. Before shifting budget, confirm how each format reports conversions, what a "lead" from Business Agent counts as, and how Highlighted Answers attribute value. Start with a contained test budget and a clear control so you can tell incremental lift from cannibalized organic clicks.
5. Watch the disclosure and policy layer
Gemini-generated ads intersect with the AI-transparency rules Google and regulators rolled out in 2026. Keep your AI-label settings consistent, and if you advertise in the EU, India or New York, confirm that agent-driven and machine-generated creative meet local disclosure requirements. Platform controls and legal obligations remain two separate things.
The competitive backdrop
Google is not moving in a vacuum. OpenAI has expanded its ChatGPT ads pilot into new markets with thousands of brands running through ad-tech partners, while other AI search players are still deciding whether to carry advertising at all. We unpacked that divergence in our look at how AI search advertising is splitting in 2026. Google's advantage is distribution — AI Mode now reaches an enormous audience inside a product people already use to buy — and Gemini ad formats are how it converts that reach into revenue without sending users to a separate chat app.
For advertisers, that means the center of gravity in paid search is shifting from the auction to the assets. The winners in this next phase will be the brands whose product data is clean, whose pages answer real questions, and whose creative gives Gemini something worth remixing. The losers will be the ones who treat these formats as a new checkbox in the campaign builder and feed the machine the same thin inputs that already underperform.
The bottom line
Google's Gemini ad formats mark the point where AI stops being a backend optimizer and becomes the front-of-house of paid search — writing the ad, answering the question, and in some cases closing the conversation. None of it is fully rolled out yet, which makes now the right time to prepare rather than react. Get your feeds and pages in order, run contained tests, and keep the human signals — real positioning, honest data, genuine expertise — that no model can manufacture on your behalf.
Frequently asked questions
What are Google's new Gemini ad formats?
They are four Gemini-powered ad experiences for AI-powered Search announced at Google Marketing Live 2026: Conversational Discovery ads (query-specific generated creative), Highlighted Answers (sponsored placements inside AI answers), Business Agent for Leads (an in-ad chat that qualifies leads), and AI-powered Shopping ads for conversational shopping queries.
Are the Gemini ad formats available now?
Partially. As of mid-July 2026, Conversational Discovery ads and Highlighted Answers are in live US testing on mobile and desktop, and Business Agent for Leads is in open beta for US advertisers. AI-powered Shopping ads are expected to roll out to US advertisers later in 2026.
What is Business Agent for Leads?
It is an AI chat experience inside a lead-generation ad. Instead of completing a static form, the user talks to a Gemini agent trained on the advertiser's website, which answers questions and qualifies the lead in the conversation. It effectively turns your site content into a live sales script, so page accuracy matters more than ever.
How do Gemini ad formats change campaign work?
They move the advertiser's leverage upstream — from writing fixed headlines and tuning bids to supplying clean product feeds, accurate landing pages and strong brand assets that Gemini composes from. Measurement also changes, because conversational and in-answer placements do not map neatly onto the traditional impression-and-click model.
Do I need to disclose that my ads were made with AI?
Google applies disclosures automatically when you build creative with its own generative tools, and it offers AI-label settings you can toggle. Using those settings does not guarantee legal compliance, so if you advertise in regulated markets such as the EU, India or New York, confirm your disclosure obligations separately.
