What is
AI SEO?
AI SEO is search engine optimisation for a world where an increasing share of searches are answered by AI. It combines traditional SEO principles with new techniques aimed specifically at visibility in ChatGPT, Gemini, Perplexity and Google AI Overviews. Where traditional SEO is about positions in Google, AI SEO is about getting cited in AI answers. It is not a replacement for SEO but a necessary extension. 86% of UK SEO professionals have already integrated AI into their strategy. This guide explains what AI SEO is, how it differs from traditional SEO and GEO, and which practical techniques you can apply.

AI SEO: the definition
AI SEO is the process of optimising your online presence for both traditional search engines and AI platforms. It is an overarching strategy that combines traditional SEO and GEO (Generative Engine Optimisation) into an integrated approach. The goal: being visible everywhere your customers search, whether that is Google, ChatGPT, Perplexity or Google AI Overviews.
The term AI SEO is used in two ways in practice. The first meaning is using AI tools to improve your SEO work: AI for keyword research, content creation, technical audits. The second meaning, and the focus of this article, is optimising your content so that AI search engines cite you in their answers. These are fundamentally different activities that require different approaches.
Two meanings, one strategy
The distinction matters. Using AI as a tool for SEO is an operational improvement. AI SEO as a visibility strategy is a fundamental shift in how you think about online marketing. It is no longer just about "how do I rank higher in Google?" but also "how do I get ChatGPT to recommend my business?" For UK businesses, where 54% of adults already use AI tools and AI Overviews appear in over 40% of searches, this is not a future concern. It is a current reality.
AI SEO, SEO and GEO: the relationship
Traditional SEO
Optimisation for Google search results. Focus on positions, backlinks, keywords. Result: clicks to your website.
GEO (Generative Engine Optimisation)
Optimisation specifically for AI answers. Focus on quotability, structured data, authority. Result: citations in AI. More in what is GEO?
AI SEO (the combination)
The integrated strategy that combines SEO and GEO. Being visible in Google and in AI platforms. Result: clicks and citations across all platforms.
Why traditional SEO is no longer enough
Google processes 8.5 billion searches per day. That is still enormous. But the way those searches are answered is changing fundamentally. Google AI Overviews now appear in over 40% of UK searches and reduce click-through rates by 54% for position one. The user reads the AI answer and does not click through.
At the same time, a significant share of search volume is shifting to AI platforms like ChatGPT, Gemini and Perplexity. UK visits to ChatGPT grew 387% year-on-year. These platforms do not work with positions and blue links. They give direct answers and cite sources. If you are not in those citations, you do not exist for a growing share of your target audience.
The impact is already measurable. Organic clicks dropped 38% on queries where AI Overviews appear. Zero-click searches rose from 54% to 72% overall. The hospitality sector has been hit hardest with a 6.7% annual traffic decline. Fashion followed with 3.4%. These are not theoretical projections. They are recorded changes in UK traffic data.
From one system to an ecosystem
Traditional SEO focuses on one system: Google. AI SEO focuses on an ecosystem: Google plus ChatGPT plus Gemini plus Perplexity plus Google AI Overviews. Each platform has its own selection criteria, its own sources and its own preferences. A strategy aimed only at Google misses four of the five platforms where your customers are searching.
The good news is that the fundamentals of strong SEO also work for AI SEO. Clear content, technical speed, mobile optimisation and authority matter for both. The difference lies in the extra layer that AI SEO adds: quotability, structured data, multi-platform presence and specific content formats that AI can easily process.
Consider how this plays out for a UK business. A Manchester-based accountancy firm ranks well on Google for "accountant Manchester" thanks to years of SEO work. But when a potential client asks ChatGPT "Which accountant in Manchester is best for a startup?", the firm might not appear at all. ChatGPT looks for quotable content, specific service descriptions, client reviews and third-party mentions. Traditional ranking signals alone do not determine who gets recommended.
98% of UK marketers plan to increase their AI SEO investment in 2026. That tells you the industry recognises the shift. The question is whether individual businesses are adapting fast enough. 67% of small UK businesses now use AI for content marketing and SEO, but far fewer have adjusted their actual strategy for AI visibility.
AI SEO is not "using AI for SEO." It is "doing SEO for AI." That distinction will determine which businesses grow over the coming years.
The AI SEO strategy: from keywords to search intent
The biggest strategic shift in AI SEO is the transition from keywords to search intent. With traditional SEO, you optimise for specific keywords: "solicitor Leeds" or "best CRM for SMEs." With AI SEO, you optimise for the intent behind the question: why is someone looking for a solicitor? What is their specific situation? What do they want to achieve?
AI platforms understand intent far better than Google's traditional algorithm. When someone asks ChatGPT "I have just started a limited company in Edinburgh and need someone to handle my VAT registration and bookkeeping, ideally not too expensive", AI grasps the context (new business), the legal structure (limited company), the location (Edinburgh), the needs (VAT registration, bookkeeping) and the preference (affordable). AI matches that intent with businesses that offer exactly that combination.
Specific content for specific questions
For businesses, this means your content needs to become much more specific. Instead of a generic "services" page, you need pages that address specific audiences and situations. "Bookkeeping for limited companies in Edinburgh" is more specific than "Bookkeeping for businesses" and gets matched by AI more often to relevant questions. The more precisely your content mirrors the questions your customers actually ask, the more frequently AI will cite you.
A second strategic shift is the transition from individual pages to a content ecosystem. With traditional SEO, you could score with a handful of well-optimised pages. With AI SEO, you need a broader content offering that demonstrates your expertise from multiple angles. Blog articles, FAQs, case studies, comparison pages and service descriptions together form a knowledge platform that AI recognises as authoritative.
The third shift is from on-page to everywhere. Traditional SEO focuses heavily on your website: technical optimisation, content, internal links. AI SEO requires a broad online presence: Google Business Profile, Trustpilot, Checkatrade, trade directories, social media, industry publications. AI platforms crawl all those sources and combine them into a picture of your business. The broader and more consistent that picture, the more trustworthy you are to AI. Read more about this in how AI collects business information.
From one-off to ongoing
The fourth shift is from one-off to ongoing. Google positions are relatively stable. AI citations change constantly. The UK shows 60% citation volatility in AI results. An AI SEO strategy requires structural monitoring, regular content updates and continuous adjustment based on data. It is not a project but a process. Understanding how AI assembles its answers helps you understand why this ongoing approach is essential.

Practical AI SEO techniques for 2026
Intent-driven content
Write content that answers specific questions, not just targets generic keywords. "What does a solicitor charge for conveyancing in London?" is more specific than "solicitor London." AI matches intents, not keywords. The more specific your content, the more often AI matches you to relevant queries.
Structured data implementation
JSON-LD schema markup is not optional in AI SEO. Implement LocalBusiness, Organization, FAQPage, Service and Review schema. This gives AI structured information about your business that it can process directly without guessing. 68% of AI-cited websites have strong structured data.
Strengthen E-E-A-T
Experience, Expertise, Authoritativeness, Trustworthiness. Add author information, reference sources, display publication dates, maintain a complete about page. For UK regulated professions, include your professional body registration. Sites with strong trust signals are 2.7x more likely to be cited by AI.
Multi-platform presence
Ensure your business information is consistent across your website, Google Business Profile, Trustpilot, Checkatrade, industry directories and social media. AI combines information from all these sources. Inconsistencies (different phone numbers, outdated addresses) reduce AI's confidence in recommending you.
Quotable content structure
Short paragraphs of 40 to 60 words, H2 headings phrased as questions, answer-first structure, FAQ sections, comparison tables and concrete figures. AI extracts passages. Make those passages as strong and self-contained as possible. Learn more in how AI reads websites.
AI visibility monitoring
Measure not just Google positions but also AI citations. How often are you cited, on which platforms, with what sentiment and for which questions? That data steers your optimisation. Without monitoring, AI SEO is guessing in the dark. VestVale automates this across all major AI platforms.
KPIs for AI SEO: what should you measure?
Traditional SEO measures positions per keyword, organic traffic and conversions from Google. AI SEO adds a new layer of metrics that measure visibility in AI answers. Without those metrics, you are flying blind in a world where an increasing percentage of your potential customers are searching through AI.
The first and most important metric is AI citation frequency: how often is your business or website mentioned in AI answers to relevant questions? This is the equivalent of "position 1 in Google" for the AI world. A higher citation frequency means more visibility, more brand impressions and ultimately more customers. For UK businesses, this metric is becoming as important as organic traffic.
Measuring platform spread
The second metric is platform spread: on which AI platforms are you cited? If you only appear in Perplexity but not in ChatGPT, you are missing the largest platform. ChatGPT holds 60.4% market share among AI tools. Gemini has 15.2%. Ideally, you want to be visible across all major platforms. That spread gives you a broader base and less dependency on any single platform.
The third metric is sentiment: how is your business described when it is cited? Positively, neutrally or negatively? Are your strengths emphasised or your weaknesses? The way AI talks about your business is at least as important as whether you are cited at all. A citation that says "frequently criticised for slow response times" is worse than no citation.
The fourth metric is AI referral traffic: how many visitors come to your website from AI platforms? Check your analytics for referrals from chat.openai.com, perplexity.ai and gemini.google.com. This traffic is growing rapidly and converts at dramatically higher rates than traditional Google organic traffic. ChatGPT referrals convert at 15.9% compared to 1.76% for Google organic.
The trend over time
The fifth metric is the trend over time. One-off measurements tell you very little because AI answers vary between sessions. What matters is the trend over weeks and months. Are you being cited more often? On more platforms? With more positive sentiment? That trend line tells you whether your AI SEO strategy is working. VestVale tracks all five of these metrics automatically, giving you the data you need to steer your strategy.
Frequently asked questions about AI SEO
Can I do SEO and AI SEO at the same time?
Yes, and you should. AI SEO is not a replacement for traditional SEO but an extension. A strong Google position is necessary because AI platforms search the web and use Google's index as a starting point. The businesses that perform best combine traditional SEO with AI-specific optimisation as an integrated strategy. Many AI SEO techniques also improve your traditional search performance.
What is the difference between AI SEO and GEO?
GEO (Generative Engine Optimisation) focuses specifically on getting cited in AI answers. AI SEO is the broader strategy that combines traditional SEO and GEO. In practice, the terms are often used interchangeably. The key point is that you need to optimise for both Google and AI platforms. Read more in what is GEO?
Which content elements help most for AI SEO?
Structured data (JSON-LD schema markup), FAQ sections with schema, intent-driven content that answers specific questions, comparison tables, concrete numbers and statistics, and author information that strengthens E-E-A-T. Avoid vague marketing copy and focus on concrete, factual information. The Princeton GEO study showed that adding citations increases visibility by 115%.
How do I know if my AI SEO is working?
Measure four things: AI citation frequency (how often you are cited), platform spread (which AI platforms mention you), sentiment (how you are described) and AI referral traffic (visitors arriving from AI platforms). The trend over months matters more than any single measurement. Tools like VestVale automate this monitoring across all major platforms.
Is AI SEO relevant for small businesses?
Particularly relevant. Small businesses often serve specific niches and locations, which is exactly what AI needs to match user queries. A sole trader electrician in Bristol who clearly states their specialisms, coverage area and pricing is easier for AI to recommend than a national chain with generic content. The key is specificity and consistency across platforms.
How quickly will AI SEO produce results?
First citations typically appear after one to three months. Structural visibility with consistent citations across multiple platforms takes six to eighteen months. The fastest wins come from implementing structured data and rewriting existing content for quotability. Long-term results come from authority building through reviews, guest publications and consistent multi-platform presence.
