AI Search Optimisation: New Guidelines from Google

Essential Strategies for Optimising AI Search According to Google’s Insights

On 15 May 2026, Google released its first comprehensive guide focused on optimising for generative AI Search Optimisation features integrated within its Search platform. This launch came at a pivotal moment, as AI Mode now caters to over one billion users monthly, with AI Overviews appearing in 48% of all searches. This rapid expansion has led to a flurry of speculation and misinformation within the SEO sector, accompanied by a surge of overpriced “GEO hacks” that ultimately underperform.

John Mueller, part of Google's Search Relations team, shared this guide via the Google Search Central Blog, clearly conveying the guide's critical message:
There is no distinct practice known as AEO (Answer Engine Optimisation) or GEO (Generative Engine Optimisation). These terms simply represent traditional SEO strategies adapted for an AI context.

Understanding This Information is Crucial! Over the past two years, numerous agencies have marketed “AI Search optimisation” packages, advocating techniques such as content chunking and the use of llms.txt files, among other methods.

Google Provides Valuable Clarity Amidst Confusion, Helping Identify What Enhances Visibility and What Wastes Resources.

Understanding the Basics: AI Search Optimisation Features Are Based on Core Ranking Systems!

The AI Search optimisation guide underscores a vital point: The initial generative AI features in Google Search do not supersede existing ranking systems; they are built upon them.

Google explains that AI Overviews and AI Mode utilise “retrieval-augmented generation (RAG),” a technique in which AI responses are based on information derived from web pages that already perform well within Google's traditional indexing framework. Initially, Google's systems gather relevant, high-quality pages based on established ranking signals and then curate information from these sources into an AI-generated response.

This indicates that a web page with poor crawlability, minimal content, or technical SEO problems will not be referenced in AI Overviews, even if it claims to be “optimised for AI.” The essential requirement remains that fundamental SEO practices must be properly implemented.

Key Insight: Your SEO strategy should be executed with meticulous attention to detail. Strong technical foundations, valuable content, and a well-structured site are now more essential than ever, as these factors determine whether your content can be cited by AI.

What Factors Improve Visibility in AI-Generated Responses?

Google's AI Search Optimisation guide identifies five critical areas that enhance visibility in AI-generated search results:

1. Create Unique, Non-Commoditised Content for Optimal AI Citation

The guide clearly states that content which can be autonomously generated by AI lacks value for citation. Google's algorithms favour pages that display genuine expertise, original research, or personal experiences that cannot simply be reproduced by synthesising publicly available data.

Examples of Commodity Content (Low AI Citation Value):

• Generic articles providing “10 tips for…” that simply reiterate common knowledge
• Content summarising existing discussions from other websites
• Basic “What is X” explanations that lack a unique perspective

Examples of High-Value Content (Strong Citation Potential):

• Authentic reviews based on actual product testing experiences
• Case studies authored by practitioners featuring specific data
• Original research employing proprietary data or methodologies
• Expert analysis that connects concepts overlooked by general sources

The principle is clear: if a large language model can generate comparable content by training on publicly available web data, your page will not receive citation. Only content that reflects knowledge or experiences inaccessible to an AI system qualifies for inclusion.

2. Optimise for Local and Shopping Searches Using Google’s Native Tools

For businesses focusing on local and product-related searches, Google's guidance highlights the necessity of leveraging their ecosystem: the Google Business Profile for local services and the Google Merchant Center for e-commerce ventures.

This is crucial as AI responses for local and shopping-related queries are derived directly from these data sources. Accurate business hours, current pricing, verified categories, and recent reviews significantly impact what Google highlights in AI Overviews and AI Mode.

Actionable Task: Conduct an audit of your Google Business Profile and Merchant Center feed. AI responses will depend on outdated or incomplete information from these sources—not from your website.

3. Maintain a Clear and Accessible Page Structure Without Mandatory Chunking

Google's algorithms can comprehend entire pages and extract relevant sections without requiring content to be divided into small, distinct segments. The guide explicitly states that there is no obligation to chunk content for AI consumption.

This guidance counters a prevalent recommendation in the SEO community. Many agencies have advised clients to break content into 300-500 word segments for optimal AI parsing. Google's guidance indicates that this practice is unnecessary and may be counterproductive, fragmenting the reading experience without offering measurable SEO benefits.

Instead, focus on:

• Using clear headings that accurately reflect the content that follows
• Crafting direct opening statements that address the implied question
• Ensuring a logical content flow prioritising human readers

4. Incorporate Structured Data for Rich Results, Not Just for AI Search Optimisation

The guide clarifies that no specific schema markup is necessary for AI responses. Still, structured data is valuable as it enhances eligibility for rich results in conventional search—where traditional visibility contributes to AI citation eligibility.

Utilise structured data to qualify for features such as:

• FAQ schemas for informative content
• Product schemas for e-commerce
• Organisation and LocalBusiness schemas to amplify brand visibility

The distinction is crucial: structured data supports rich results but does not directly influence AI Overviews. Avoid implementing schema with the expectation of boosting AI citations; instead, use it to enhance visibility in standard search.

5. Prepare Your Site for Agent Accessibility in Transactional Environments

In the domains of e-commerce, bookings, and service-oriented businesses, Google emphasises the importance of the Universal Commerce Protocol (UCP)—an evolving open standard co-developed with Shopify and supported by over 20 companies. UCP enables AI agents to facilitate transactions directly on websites.

The guide also mentions that browser agents assess websites through screenshots, DOM inspection, and accessibility trees. To prepare for agent accessibility, consider the following:

• Ensure essential content does not depend on JavaScript rendering
• Maintain a clean, crawlable HTML structure
• Keep pricing and availability information up to date
• Develop FAQ sections that provide direct answers to purchase-related inquiries

While agent readiness may not be an immediate concern for many businesses, it is prudent to monitor UCP adoption as a strategic priority for the future.

Which Practices Should You Abandon Based on Google's AI Search Optimisation Guide?

The guide outlines specific tactics that pose unnecessary risks without delivering any corresponding benefits:

1. Discontinue Content Chunking for AI Optimisation

• Discontinue: Dividing content into small segments aimed at AI parsing.
• Reason: Google's systems can automatically extract relevant excerpts from complete pages. Fragmenting content diminishes the reading experience for human visitors and fails to increase the likelihood of AI citation.

2. Stop Creating llms.txt or AI-Specific Files

• Discontinue: Producing machine-readable files designed solely for AI consumption.
• Reason: While Google can crawl and index various file types, this does not confer any special consideration for those files in AI responses. Creating llms.txt or similar files does not enhance visibility; it merely complicates maintenance.

3. Avoid Restructuring Content Exclusively for AI Systems

• Discontinue: Altering your writing specifically for AI consumption.
• Reason: Large language models comprehend synonyms, paraphrases, and various sentence structures. There is no need to optimise for exact phrase matching or to excessively use long-tail keywords. Write primarily for human readers; AI systems will interpret it effectively.

4. Stop Pursuing Inauthentic Brand Mentions

• Discontinue: Generating fake mentions across forums, blogs, or social media to artificially enhance perceived authority.
• Reason: Google's core ranking algorithms assess content quality, and spam filtering actively suppresses manipulation attempts. Inauthentic mentions can severely undermine your site's trust signals and are not a sustainable strategy for achieving visibility.

5. Refrain from Overemphasising Structured Data

• Discontinue: Implementing complex schema specifically to influence AI responses.
• Reason: Structured data is unnecessary for AI Overviews or AI Mode. While it has value for rich results in standard search, there is no unique markup that enhances citation likelihood for AI. Focus schema efforts on genuine requirements rather than speculative AI optimisation.

Your Actionable AI Search Optimisation Strategy

Based on Google's insights, here’s how to prioritise your optimisation efforts:

Tier 1 (Immediate Actions):

1. Evaluate your top 20 pages for content quality—do they provide non-commoditised value that AI cannot replicate?
2. Ensure your Google Business Profile and Merchant Center data are precise and up to date.
3. Eliminate any “AI optimisation” tactics that contradict the guide (such as chunking, llms.txt files, and unnecessary schema).

Tier 2 (Next Three Months):

1. Enhance your entity presence across reputable external platforms—consistent brand mentions in respected publications can enhance AI citation opportunities.
2. Shift towards topical depth instead of isolated keyword pages—developing content clusters that explore a topic from multiple perspectives can perform better in AI Mode's fan-out queries.
3. Add AI citation tracking to your reporting alongside traditional ranking metrics (platforms like Semrush, Ahrefs, and BrightEdge now include AI Overview data).

Tier 3 (Ongoing Monitoring):

1. Keep track of UCP adoption if you are involved in e-commerce or transactional services.
2. Evaluate whether your product or service data can be structured as reliable, current feeds for AI agent use.

Core Takeaway

Google's AI Search optimisation guide conveys a straightforward message: SEO remains SEO. The fundamentals have not shifted—they have merely been recontextualised for new platforms. Your technical foundations, the quality of your content, and a user-centric approach dictate whether your pages qualify for AI citation. The “GEO hacks” circulating in the industry are either superfluous, ineffective, or carry significant risks.

Cease investing in AI optimisation tactics that contradict Google's guidance.

Refine your execution of the fundamentals, create content that exemplifies genuine expertise, and monitor AI citation as a distinct key performance indicator alongside your traditional ranking metrics.
