Google has published an official guide on website optimization for its AI-powered search features, taking the position that traditional SEO best practices remain effective and that no special measures are required for AI. Among practitioners, there is a growing view that third-party credibility will become increasingly important in the AI search era. At the same time, Google announced enhancements to personalization features for its Google Discover feed. A chat interface that allows users to specify in natural language what content they want to see or exclude will be rolled out within days. The feed will adjust instantly, and user requests will be remembered. Additional features include a button to follow publishers on the spot and customizable topic-based audio briefings in Google News.
Key Elements
Google has successively unveiled new directions for search experience personalization and website management guidelines for the AI search era. The company published an official guide called the “AIO Guide” for optimizing sites for search features that incorporate generative AI, and continues to update it. Meanwhile, the company announced that it will introduce a conversational interface within days for Google Discover, its mobile content distribution feed, allowing users to directly specify in natural language what information they want to see.
SEO in the AI Search Era: Fundamentals Unchanged
The AIO Guide published by Google lays out the company’s approach to website optimization for AI search features. The guide explicitly states that traditional search engine optimization (SEO) best practices remain effective for AI search features as well. It recommends creating unique, valuable content for users while taking the position that no special measures are required for AI features.
The attention this guidance has drawn reflects the anxiety among website operators amid the spread of AI search: “How can we get AI to cite our site?” Google’s official position can be seen as a continuation of its traditional approach—that enhancing the intrinsic value of content, rather than gimmicks or tricks, is the most reliable path.
At the same time, there is a growing view that the importance of third-party credibility is increasing in AI search era SEO. This is because when AI generates answers, it tends to reference mentions and evaluations from multiple independent sources rather than self-assertions from a single site. While Google’s official guide does not directly address this point, an analysis is spreading among search marketing practitioners that off-page measures such as earning backlinks and expanding brand mentions will carry greater weight.
Discover: Direct Feed Control Through Natural Language
Google announced three personalization enhancements for the Discover feed this week.
The first is a “Preferred Sources” button that publishers can embed on their own sites. Readers will be able to follow a publisher without leaving the page.
The second is customizable daily audio briefings by topic in the Google News app.
The third is a chat interface that allows users to directly describe in natural language what content they want to see in their Discover feed.
With this conversational feature, users can tap the three-dot menu on any item in the feed and enter specific instructions such as “Show me long-form, in-depth articles about smart home technology, but exclude product news and press releases.” According to Google, the feed will adjust instantly and requests will be remembered. The feature is scheduled to roll out in the Google app “within days.”
A Shift from Algorithm-Driven to User-Driven
Until now, the Discover feed has been built entirely by algorithms based on cross-ecosystem activity data, including browsing history, search queries, and YouTube viewing behavior. The options available to users were limited: “show less content like this,” “not interested,” “heart an article,” or “block a specific publisher.”
This conversational customization marks a turning point in which control over feed composition is partially shifted from the black box of algorithms to explicit user intent. As search experience personalization and AI-powered information organization intersect, Google has chosen a mechanism that lets users directly articulate what they want to see.
Implications for Publishers and Marketers
This series of announcements presents two challenges for content creators. First, to increase visibility in AI search, content uniqueness and earning third-party credibility are becoming more decisive than technical optimization. Second, in algorithm-driven feeds like Discover, it is becoming important to be an entity that users actively choose to “see”—in other words, building brand strength that earns follows.
Google’s explicit statement in its official guide that “no special measures are required” can be interpreted as a message that resources should be invested in long-term trust-building rather than short-term tactics. SEO competition in the AI search era is likely to be decided in more fundamental domains: content quality and brand reputation.
