What Google Announced at Marketing Live 2026
Google introduced a set of Gemini-powered ad formats designed to appear inside AI Mode and conversational Search results. These include Conversational Discovery Ads that respond to a user's specific question within an AI Mode answer, Highlighted Answers that surface eligible ads inside list-style AI responses, AI-Powered Shopping Ads where Gemini generates a per-query product explainer, and a Business Agent for Leads that lets users interact with a brand's AI chat agent inside the ad instead of filling out a form. The common thread is that Gemini interprets the intent behind a query and assembles ad creative for that specific conversation.
How Conversational Ads Differ From Today's Search Ads
Traditional Search ads match keywords and serve a fixed headline and description. The new formats are generated in context, so the creative shown can vary by query and by the surrounding AI response. Google has stated that the Gemini model synthesizes information about a product or service and displays that context alongside the advertiser's own creative. In practice this means less control over the exact wording a user sees and more reliance on the assets and feeds you provide.
What the AI Max Performance Numbers Actually Say
Google reports that advertisers who turn on AI Max for Search typically see about 14% more conversions or conversion value at a similar CPA or ROAS, and up to 27% for campaigns that lean heavily on exact and phrase match. This figure comes from Google's own data and, per Google, excludes retail advertisers. Independent analysis of retail campaigns has shown more mixed results, including higher CPA in some accounts, so the 14% figure should be read as a non-retail benchmark rather than a guarantee for every advertiser.
What This Means for Your Budgets
Conversational and AI Mode placements expand where your ads can appear, which can shift spend toward queries and surfaces you did not previously target. Because creative is generated dynamically, the quality of your assets, product feeds, and conversion tracking matters more than before. Plan for a testing window with clear CPA or ROAS targets, watch where impressions and spend are actually going, and treat Google's reported lifts as a starting hypothesis to validate against your own results.
How to Prepare Now
Tighten your conversion tracking and make sure your bidding targets reflect real business goals before enabling new AI-driven placements. Audit your creative assets and product data so Gemini has accurate inputs to work from. Review search terms and placement reports regularly once these formats roll out, and be ready to exclude surfaces or queries that do not convert. Start with controlled tests rather than switching everything at once.
