AI SEO

AI SEO is the practice of making a website and brand visible in AI-powered search experiences, such as Google AI Overviews and AI Mode, ChatGPT search, Gemini, Perplexity, Microsoft Copilot and Claude. It also covers using AI tools responsibly in your own SEO work. The first meaning is the one most businesses now care about: being mentioned, cited and recommended when people ask AI for answers.

How AI search differs from traditional search

Traditional search shows a list of links. AI search reads many sources and writes an answer, often citing a handful of them. This changes what success looks like:

  • Citations and mentions matter as well as rankings.
  • Fewer clicks for simple questions, as answers appear directly (Zero-Click Searches).
  • Conversational queries are longer and more specific.
  • Brand reputation across the web influences whether AI recommends you.

How AI systems choose sources

Most AI search tools combine a language model with a search index. They retrieve pages relevant to the question, then summarise them. Pages are more likely to be used when they:

  • Already rank well in traditional search engines.
  • Answer the question clearly and directly.
  • Are well structured, with descriptive headings, lists and tables.
  • Come from sources that appear trustworthy and authoritative (E-E-A-T).
  • Are accessible to the AI’s crawler and do not rely on JavaScript for core content (Rendering).
  • Contain specific facts, data and expert insight rather than generic text.

How to optimise for AI search

  1. Get the SEO fundamentals right. Strong technical health, helpful content and authority remain the foundation.
  2. Answer questions directly. Put concise answers near the top of sections, then expand (Answer Engine Optimisation (AEO)).
  3. Strengthen your entity signals. Consistent business information, Organization and Person Schema Markup, and a clear About page.
  4. Earn mentions on trusted sites. Reviews, press coverage, industry lists and community discussions shape what AI says about you (Digital PR).
  5. Publish original information that AI cannot find elsewhere: data, case studies, opinions and experience.
  6. Allow the right crawlers in Robots.txt if you want to appear in AI answers.
  7. Keep information current, especially prices, services and contact details.

Measuring AI visibility

Measurement is still developing. Useful methods include:

  • Asking AI assistants the questions your customers ask and recording whether you are mentioned.
  • Tracking referral traffic from AI tools in Google Analytics 4.
  • Monitoring brand mentions across the web.
  • Using emerging AI visibility tracking tools.

AI SEO in regulated sectors

In health, finance and legal sectors, AI systems are particularly cautious and favour authoritative sources. My article on AI in healthcare and medical SEO marketing explains what this means for clinics.

AI SEO, GEO and AEO

AI SEO overlaps with generative engine optimisation (GEO) and answer engine optimisation (AEO). The names vary, but the principles are the same: be the clearest, most trusted source on your topic.

Key Takeaways

  • AI SEO aims to get your brand mentioned and cited in AI-generated answers.
  • Strong traditional SEO is the foundation: AI tools rely on search indexes.
  • Clear answers, original information and consistent entity data improve your chances.
  • Mentions on trusted third-party sites shape what AI says about you.
  • Measure visibility by testing real questions and tracking AI referrals.
