Google AI Mode is a new optional state for Search that replaces the list of links with a chat capable of maintaining context, generating sub-searches and responding with text, images and web sources.

Supported by the Search with Stateful Chat patent (US 20240289407 A1) and an upgrade to the Gemini model, it began to be made available in the US after Google I/O 2025 and will arrive in Europe when it complies with the Digital Markets Act.

This guide explains the technology, timeline, legal implications, impact on traffic and provides an SEO checklist for 2025-26.

Google AI Mode – Complete Guide to Patent, Roadmap, SEO Impact and Best Practices

Google Search is evolving from ‘ten blue links’ to AI-generated answers. After AI Overviews, the company is launching AI Mode – an entire conversational search mode that combines multimodal reasoning, context persistence and cited links.

How AI Mode works

1. Intention interpretation: extracts entities from the question.
2. Fan-out of sub-queries: generates and executes parallel searches.
3. Synthesis by LLM: Gemini composes a long answer with clickable links.
4. Stateful session: the chat history is saved and reused. These steps are described in the patent and in the official documentation.

The ‘Search with Stateful Chat’ patent (US 20240289407 A1)

Published on 29-Aug-2024, this patent defines: Google Patents

• Session memory that stores queries, clicks and preferences.
• Layered architecture (FIG. 9): analysis → fan-out → ranking → generation.
• Personalised corpus: possibility of restricting to specific sources (Drive, Gmail or web verticals).
• Objective: to reduce manual steps and offer complete answers in a single interaction.

Metrics in Google Search Console

• New ‘AI Features’ filter will aggregate impressions and clicks from AI Mode and Overviews, without the possibility of separating them. Search Engine Land
• Clicks originating from chat do not carry a referrer and appear as ‘direct’ traffic. Search Engine Land
• We recommend measuring micro-conversions (scroll, CTA, subscriptions) in addition to pageviews.

Impact on traffic and monetisation

Initial studies show a drop of up to 34 % in clicks when AI Overviews appear, a trend that could be repeated in AI Mode. Digital Content Next | Vox

Publishers report referral losses comparable to 2016 Featured Snippets.
