AI Search Optimisation: New Guidelines from Google

Master Google's Strategies for AI Search Optimisation and Elevate Your SEO Game

On 15 May 2026, Google released its inaugural comprehensive guide aimed at optimising generative AI Search Optimisation features within its Search platform. This guide was timely, as AI Mode now caters to over one billion monthly users, with AI Overviews appearing in 48% of all search queries. This rapid expansion has led the SEO industry into a whirlwind of speculation and misinformation, alongside a surge of overpriced “GEO hacks” that ultimately fail to deliver results.

John Mueller, a prominent member of Google's Search Relations team, announced this guide via the Google Search Central Blog, clearly articulating the guide's key 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.

This Information is Essential! Over the past two years, various agencies have marketed “AI Search optimisation” packages, promoting strategies like content chunking and the use of llms.txt files, among others.

Google Provides Clear Guidance Amidst Uncertainty, Helping Users Identify What Enhances Visibility and What Wastes Resources.

Understanding the Basics: AI Search Optimisation Features are Built on Core Ranking Systems!

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

Google clarifies that AI Overviews and AI Mode utilise “retrieval-augmented generation (RAG),” a technique whereby AI responses are rooted in information sourced from web pages that already perform well in Google's traditional indexing framework. Initially, Google's systems retrieve pertinent, 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, insufficient content, or technical SEO flaws will not be referenced in AI Overviews, even if it is claimed to be “optimised for AI.” The fundamental prerequisite remains that basic SEO practices must be properly executed.

Key Insight: Your SEO strategy should continue to be implemented with precision. Robust technical foundations, valuable content, and an organised site structure are now more crucial than ever, as these factors determine your content's eligibility for AI citation.

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 to Maximise AI Citation

The guide clearly states that content that can be autonomously generated by AI lacks citation value. Google's algorithms favour pages that exhibit genuine expertise, original research, or personal insights that cannot be easily replicated by synthesising publicly available information.

Examples of Commodity Content (Low AI Citation Value):

• Generic articles presenting “10 tips for…” that simply repeat common knowledge
• Content summarising existing discussions from other websites
• Basic “What is X” explanations that fail to offer a unique perspective

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

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

The principle is straightforward: if a large language model can produce similar content by training on publicly available web data, your page will not attract citation. Only content that reflects knowledge or experiences unreachable by an AI system is eligible for inclusion.

2. Optimise for Local and Shopping Searches Using Google’s Built-in Tools

For businesses focusing on local and product-based searches, Google's guidance emphasises the importance 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 derive directly from these data sources. Accurate business hours, up-to-date pricing, verified categories, and recent reviews significantly affect what Google chooses to showcase 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 your website.

3. Maintain a Clear and Accessible Page Structure Without the Need for 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 necessity to chunk content for AI consumption.

This statement counters a common recommendation within the SEO community. Many agencies have suggested that clients break content into 300-500 word segments for optimal AI parsing. Google's guidance indicates that this practice is not only unnecessary but can also be counterproductive, disrupting the reading experience without providing any measurable SEO advantage.

Instead, focus on:

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

4. Implement Structured Data for Rich Results, Not Exclusively for AI Search Optimisation

The guide clarifies that no special schema markup is necessary for AI responses. structured data remains advantageous 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 boost brand visibility

The distinction is critical: structured data supports rich results but does not directly benefit AI Overviews. Avoid implementing schema with the expectation of enhancing AI citations; instead, leverage it to improve visibility in traditional search.

5. Prepare Your Site for Agent Accessibility in Transactional Environments

In the domain 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 endorsed by over 20 companies. UCP enables AI agents to facilitate transactions directly on websites.

The guide also notes 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 current
• Develop FAQ sections that provide direct answers to purchase-related queries

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 Discontinue Based on Google's AI Search Optimisation Guide?

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

1. Stop Content Chunking for AI Optimisation

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

2. Halt the Creation of llms.txt or AI-Specific Files

• Stop: Producing machine-readable files tailored exclusively for AI consumption.
• Reason: Although Google can crawl and index various file types, this does not grant those files any special consideration in AI responses. Creating llms.txt or similar files does not improve visibility; it simply complicates maintenance.

3. Avoid Restructuring Content Solely for AI Systems

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

4. Discontinue Pursuing Inauthentic Brand Mentions

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

5. Refrain from Overemphasising Structured Data

• Stop: Implementing complex schema specifically to influence AI responses.
• Reason: Structured data is not required for AI Overviews or AI Mode. While it holds value for rich results in standard search, there is no unique markup that enhances citation probability for AI. Focus schema efforts on genuine requirements rather than speculative AI optimisation.

Your Actionable AI Search Optimisation Plan

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 accurate 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 improve 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. Assess whether your product or service data can be structured as reliable, current feeds for AI agent use.

The Key Takeaway

Google's AI Search optimisation guide delivers a straightforward message: SEO remains SEO. The fundamentals have not changed—they have simply been adapted for new platforms. Your technical foundations, the quality of your content, and a user-centric approach determine whether your pages qualify for AI citation. The “GEO hacks” circulating in the industry are largely unnecessary, ineffective, or pose active risks.

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

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