SEO expert reveals Google AI Mode patent details
Search marketing specialist details nine-step process that fundamentally changes content discovery and ranking mechanisms.
Michael King, founder of iPullRank and USA Today Top 10 SEO professional, analyzed Google's "Search with stateful chat" patent application that powers AI Mode functionality. The analysis, shared today, reveals a sophisticated nine-step system that processes queries through synthetic expansion and multi-stage reasoning before generating natural language responses.

According to King's analysis, "The architecture of Google's AI Mode, as depicted in FIG. 9 of the patent application, represents a multi-stage, reasoning-informed system that transitions from query interpretation to synthetic expansion to downstream natural language response generation." The patent document, published as US20240289407A1 on August 29, 2024, describes fundamental changes to how search engines process user queries and determine content visibility.
The patent filing represents significant implications for the marketing community as it demonstrates how artificial intelligence systems prioritize content inclusion based on comprehensive topic coverage rather than traditional keyword matching. King emphasized that "each step of this flow has major implications for how visibility is earned, and why traditional SEO tactics are insufficient in this environment."
Multi-stage processing system
The patent describes a method where "a query may be received, e.g., from a client device operated by a user" and "contextual information associated with the user or the client device may be retrieved." The system then generates what Google terms "synthetic queries" - multiple reformulated versions of the original search intent that expand the retrieval scope beyond exact query matches.
According to the patent documentation, "generative model (GM) output may be generated based on processing, using a generative model, data indicative of the query and the contextual information." This approach allows the system to understand user intent through contextual analysis rather than relying solely on keyword interpretation.
The patent reveals that search result document selection occurs across multiple query variations simultaneously. The system processes "a set of search result documents" where "selecting the set of search result documents including selecting, for inclusion in the set, a plurality of query-responsive search result documents based on the query-responsive search result documents being responsive to the query and the one or more synthetic queries."
King's breakdown identifies critical stages where content evaluation differs from conventional search ranking. Step four involves generating "synthetic queries" where "the LLM output guides the creation of multiple synthetic queries that reflect various reformulations of the original intent." This expansion means content creators must optimize for related concepts and supporting topics rather than focusing on individual keywords.

Classification and downstream processing
The patent describes sophisticated query classification systems that determine response types and specialized model selection. The technology processes "state data indicative of the query, contextual information, one or more of the synthetic queries, and the set of search result documents to identify a classification of the query."
King explains that "based on the classification, the system selects from a series of specialized models, e.g., ones tuned for summarization, structured extraction, translation, or decision-support." Each specialized model serves different content synthesis purposes, affecting which materials receive inclusion in final responses.
The analysis reveals that content format and structure become critical factors for AI processing. According to King's interpretation, "the LLM that ultimately interacts with your content may never 'see' the whole document, it may only consume a passage or a structured element like a list, table, or semantic triple."

Industry implications for publishers
Google's expansion of AI Mode to all United States users on May 20, 2025, fundamentally changes how content creators must approach search optimization. The patent documentation provides technical details about how these systems evaluate and synthesize content from multiple sources, creating new optimization requirements for publishers and marketers.
Publisher criticism has intensified since the May 20 rollout, with News/Media Alliance CEO Danielle Coffey stating that "Links were the last redeeming quality of search that gave publishers traffic and revenue. Now Google just takes content by force and uses it with no return, the definition of theft." The patent reveals the technical mechanisms behind these concerns, showing how AI systems synthesize information from multiple sources without necessarily driving equivalent traffic to original content creators.
The patent's "query fan-out technique" means that "when users pose questions in AI Mode, the system breaks down their inquiry into multiple subtopics and simultaneously processes hundreds of related searches to gather comprehensive information." This approach requires content creators to develop comprehensive topic coverage rather than focusing on individual keyword optimization strategies.
Technical architecture details
The patent describes how "contextual information associated with the user or the client device" includes "one or more prior queries issued by the user during the search session" and "position coordinates of the user." This contextual processing allows the system to provide personalized responses based on user history and location data.
The document reveals sophisticated state management capabilities that persist across multiple search interactions. According to the patent, "the NL responsive to the most recent query from the user may be included in subsequent contextual information retrieved during one or more subsequent turns of the search session of the user."
King's analysis emphasizes implications for traditional search marketing approaches. He notes that "presence does not guarantee traffic" because "the response is not a ranked list. It is a composition." Content inclusion depends on how well materials contribute to comprehensive responses rather than achieving high rankings for specific search terms.

Measurement and attribution challenges
The patent documentation indicates fundamental changes in how content performance should be evaluated. King suggests that SEO professionals should "measure share of Attributed Influence Value (AIV), and treat citation as both an awareness and trust-building lever" rather than focusing primarily on traditional traffic metrics.
Recent reporting indicates that "we've seen that when people click to a website from search results pages with AI Overviews, these clicks are higher quality, where users are more likely to spend more time on the site." This behavioral change suggests different evaluation criteria for measuring content success in AI-powered search environments.
The patent reveals technical complexity that extends beyond traditional optimization strategies. King concluded his analysis by noting, "I don't know y'all, sounds like this might need more than SEO." This assessment reflects broader industry discussions about how artificial intelligence systems require fundamentally different approaches to content strategy and search marketing.
Why this matters
The patent disclosure comes nine months after its August 2024 publication but gains relevance as Google expands AI Mode availability across the United States market. Understanding the technical mechanisms described in the patent helps marketing professionals anticipate how content evaluation and discovery will continue evolving in AI-powered search environments.
The patent's emphasis on "topic authority development" rather than keyword optimization represents "the most fundamental shift content creators must understand" according to recent optimization guidance. Marketing teams must adapt strategies to address comprehensive topic coverage and expert analysis rather than focusing primarily on search engine ranking factors.
The nine-step process detailed in King's analysis demonstrates how modern search systems evaluate content quality, relevance, and authority through sophisticated AI processing rather than traditional algorithmic approaches. This technical foundation affects content strategy, measurement approaches, and competitive positioning across digital marketing disciplines.
