On 20 May 2026, Google held its annual Google Marketing Live event and announced four new AI-powered advertising formats. While GML is Google's event for advertisers, the announcements directly affect organic search: ads are now embedded inside AI Mode answers, not just placed alongside them.
In brief: Conversational Discovery Ads appear inside AI Mode conversational responses. Highlighted Answers take sponsored positions in AI-generated recommendation lists. Business Agent for Leads brings a Gemini chatbot into the ad unit. Ask Advisor unifies Ads, Analytics, and Merchant Center management through AI. For SEO: another layer of monetisation in Google's AI search space.
What is Google Marketing Live 2026: Key Announcements
Google Marketing Live (GML) is Google's annual conference for advertisers and marketing professionals. Unlike Google I/O - which targets developers - GML focuses on Google Ads and search monetisation. The 2026 edition, held on 20 May, was notable for the depth of AI integration across all announced formats.
The central theme of GML 2026: AI is embedded in every layer of Google's advertising stack. The distinction between "standard ads" and "AI ads" is dissolving - AI now governs placement, format, targeting, and campaign management.
Four key announcements:
- Conversational Discovery Ads - ads embedded inside AI Mode conversational responses
- Highlighted Answers - sponsored positions within AI-generated recommendation lists
- Business Agent for Leads - a Gemini-powered chatbot built directly into ad units
- Ask Advisor - a unified AI agent for managing Ads, Analytics, and Merchant Center together
For SEO practitioners: these announcements change the composition of the search results page. Space that previously belonged to organic results is now partially occupied by a new category of advertising.
Conversational Discovery Ads: How Ads Now Appear Inside AI Mode
Conversational Discovery Ads represent a structural shift in ad placement. Previously, Google placed ads adjacent to AI Overviews - in separate blocks above or below the AI-generated summary. AI Mode changes this relationship fundamentally.
AI Mode is Google's multi-turn conversational search experience. A user asks a question, the AI generates an expanded response, the user refines or follows up, and the dialogue continues within a single session. Conversational Discovery Ads are embedded directly into the body of these AI-generated responses - not in separate ad blocks positioned around them.
In practice: A user asks "What's the most energy-efficient heat pump for a mid-sized home?" AI Mode generates a comparative analysis of options. Within that response, contextually relevant ads for specific heat pump brands appear - integrated into the text, not displayed as separate units.
How this differs from standard ads:
- Standard ads: a clearly labelled, separate block the user recognises as advertising
- Conversational Discovery Ads: embedded in the AI response, contextually tied to the conversation content
- Targeting: based on the full context of the ongoing conversation, not just individual keywords
The SEO implication: Conversational Discovery Ads occupy the same space inside AI Mode responses that previously contained only organic citations. Organic presence in AI Mode now competes directly with paid placements within the same response area.
Highlighted Answers and Business Agent: New Formats in AI Search
Highlighted Answers operate at the level of AI-generated lists and rankings. When a user asks "Best project management tools for small teams" or "Top accounting software for freelancers," AI Mode generates a curated list of options. Highlighted Answers are sponsored positions within that list - labelled as such, but positioned as part of the AI's recommendations.
The distinction from Shopping Ads: traditional Shopping Ads are a separate block placed above organic results. Highlighted Answers are embedded within the AI-generated response as recommendations. Users see them as part of the AI's analysis, with a sponsorship label.
Relevant categories: e-commerce products, local services, B2B software and services, education and courses.
Business Agent for Leads places a Gemini-powered chatbot directly inside an ad unit. A user who sees the ad can begin a conversation with the business's AI agent without leaving Google Search - no click-through to a landing page required.
What Business Agent can do within the ad unit:
- Answer questions about the product or service
- Qualify leads by exploring budget, needs, and timeline
- Schedule consultations or demo calls
- Provide pricing information on request
For service businesses - legal, medical, financial advisory, real estate - Business Agent handles initial contact around the clock, reducing dependence on landing page conversion.
Ask Advisor: The Unified AI Agent for Ads and Analytics
Ask Advisor consolidates Google Ads, Google Analytics, and Google Merchant Center into a single AI-driven interface. Prior to GML 2026, effective campaign management required navigating between three separate platforms: Ads for campaign performance, Analytics for user behaviour, Merchant Center for product feed health.
Ask Advisor eliminates these context switches.
How Ask Advisor works:
- An advertiser poses a natural-language question: "Which campaigns had the worst ROAS last quarter?"
- Ask Advisor analyses data from all three connected platforms and responds
- The conversation continues: "Which keywords in those campaigns have the highest cost-per-conversion?"
- Ask Advisor suggests specific actions and can implement changes directly
For agencies: Ask Advisor reduces the technical barrier to advanced campaign analysis. Account managers without deep platform expertise can extract meaningful insights through conversational queries rather than manual dashboard navigation.
As of GML 2026, Ask Advisor is in extended beta testing, with full access planned for later in 2026.
What This Means for SEO: AI Ad Formats and Organic CTR
Google Marketing Live is an event for advertisers, but its consequences reach directly into organic search strategy.
The new composition of the search results page in 2026:
- Traditional text ads (above organic)
- Shopping Ads and Product Listing Ads
- AI Overviews (with organic citation)
- Conversational Discovery Ads (embedded in AI Mode responses)
- Highlighted Answers (sponsored positions in AI lists)
- Organic results
A user interacting with AI Mode sees an AI-generated response with embedded Conversational Discovery Ads - and there is no guarantee they scroll to organic results below. According to Semrush (2026), the average CTR for organic position #1 in AI-heavy search results pages has declined by 61% compared to pre-AI baselines. Conversational Discovery Ads intensify this trend for queries handled in AI Mode.
Actions for SEO practitioners:
- Audit queries for AI Mode activation. Identify which target queries trigger AI Mode rather than standard search. The SERP structure for these queries is fundamentally different, and organic CTR expectations should be recalibrated.
- Evaluate Conversational Discovery Ads for relevant queries. If your product or service appears in AI Mode responses, assess whether paid placement within that space is appropriate alongside your organic strategy.
- Monitor Highlighted Answers in your category. If AI Mode generates ranked lists in your niche and your brand appears neither in organic citation nor in sponsored positions, this is a signal for E-E-A-T work.
- Strengthen E-E-A-T for organic AI citation. In a monetised AI space, organic citation in AI Overviews becomes more valuable, not less - it cannot be purchased. Content that demonstrates genuine Experience, Expertise, Authoritativeness, and Trustworthiness continues to receive priority in AI citation regardless of what competitors spend.
- Treat SEO and PPC as a unified strategy for AI Mode. In AI Mode, both channels compete in the same response space. Budget and strategy should account for both.
