At the 2026 Google Marketing Live, Google announced two native AI Mode ad formats: Conversational Discovery ads and Highlighted Answers. These are generated in real-time by Gemini based on the user's current query and can be embedded directly into AI-generated answer lists. (Context: Google Search undergoes its biggest transformation in history: Repositioning Search as a one-stop portal for AI agents) (Background: Tricking Google AI in 20 minutes: A single blog post can pollute the "only answer" seen by 2.5 billion people) For the past decade, advertisers on Google Search have been buying "placement," where keyword bidding determines who ranks at the top of search results, and users then click to jump to the brand's landing page. At this year's Google Marketing Live, these rules of the game are being replaced. Google announced a series of new ad formats powered by Gemini, shifting the advertiser's touchpoint from "the website after a user clicks" to "the AI-generated answer itself," marking a structural turning point. Google has introduced two ad formats in AI Mode, both built on Gemini's real-time generation capabilities. The first is called Conversational Discovery ads. Previously, advertisers set keyword bids, and the system matched ads to the closest query. Now, when a user asks in AI Mode, "How to make my home smell like a spa," Gemini no longer just throws out pre-set ad creative; instead, it generates an ad creative in real-time that fits the context of the query. Advertisers provide the asset library, and Gemini handles the assembly. The second is called Highlighted Answers. When AI Mode returns a list-style answer, such as "Top 5 language learning apps," highly relevant ads can appear directly within the list rather than being placed in the sidebar or at the bottom, marked only with a "Sponsored" label. Both formats include an "Independent AI Explanation," where Gemini evaluates and summarizes the product, displayed side-by-side with the advertiser's own assets. This design intentionally creates a sense of objectivity: the advertiser claims their product is good, and Gemini provides an independent assessment, with both presented together. Google emphasizes this as a transparency mechanism, but critics might point out that when the evaluator and the advertiser use the same platform, the meaning of "independent" is worth questioning. In addition to AI Mode native formats, Google is also extending its AI advertising capabilities to general search. AI-powered Shopping ads target high-consideration products: categories like refrigerators, televisions, and coffee machines that consumers repeatedly research and compare. Gemini pulls the most relevant products in real-time and writes customized explanations. Business Agent for Leads replaces static inquiry forms with real-time chat windows: clicking an ad doesn't lead to filling out a form, but to a direct conversation with the brand's AI agent, converting research behavior directly into lead lists. The key to understanding this release is acknowledging something Google is unwilling to say outright. Google Search VP Liz Reid publicly argued that "revenue under AI Overviews is relatively stable," reasoning that the decrease in clicks is offset by an increase in search volume. This claim barely holds up in financial reports: Q4 2025 Search ad revenue was $63.07 billion, up 17% year-over-year, accelerating for four consecutive quarters (Q1 10%, Q2 12%, Q3 15%, Q4 17%). However, it masks a structural problem: if paid search CTR drops by 8 to 12 percentage points, it means advertisers are spending the same amount of money for shrinking traffic reach. Increased search volume is Google's asset, not the advertiser's. Content creators and SEO practitioners have long been living with this logical gap. AI Overviews pack the answers users need directly onto the search page, eliminating the need for users to click into any website. Consequently, the zero-click rate has surged from 56% to nearly 69%, and organic search click-through rates have plummeted by 34.5%. For content platforms highly dependent on traffic, this is a direct loss in ad revenue and subscription conversion rates. Google's current solution is to shift the ad touchpoint from "the webpage after a click" to "the AI answer itself." Conversational Discovery and Highlighted Answers do not rely on users clicking away; the ads are right there in the AI's response. Direct Offers go a step further: brands upload discount rules, and Gemini combines the most relevant offers based on the query, paired with the Universal Commerce Protocol (a universal protocol that allows merchants to complete checkouts directly within the search page), so users can complete purchases without leaving search. Travel partners like Booking and Expedia are already piloting this, providing real-time special offers while AI plans trips. For advertisers,
