AI Search Optimisation: What It Is and How to Rank in 2026
When Google shows an AI Overview, the top organic result loses a big share of its clicks. Ahrefs measured a 34.5% drop for the first-ranking page in its 2025 study and reported a 58% drop when it re-ran the analysis in 2026. There is a twist. Seer Interactive found that brands cited inside those overviews earned 35% higher organic click-through than uncited brands on the same queries.
That split is what AI search optimisation is about: earning a place inside the answer. Here is what the work involves and how to do it in 2026.
What AI Search Optimisation Means
AI search optimisation is the practice of making your content easy for AI systems to find, understand and quote. Those systems include Google AI Overviews and AI Mode, ChatGPT, Gemini and Perplexity. Many marketers call it AI SEO, and it builds on classic SEO with extra attention to answer quality, structure and off-site reputation. A page on page one can still go uncited. One 2026 analysis found that only 38% of AI Overview citations overlap with top-10 organic results.
GEO vs AEO vs SEO: Clearing Up the Acronyms
The labels confuse people, so here is a working definition of each:
- SEO earns rankings and clicks in traditional search results.
- Answer engine optimisation (AEO) shapes content so search tools can lift a direct answer from it, as in featured snippets, voice answers and AI summaries.
- GEO, short for generative engine optimisation, aims to get your brand cited in answers that tools like ChatGPT and Perplexity write from scratch.
The three overlap heavily. Ahrefs’ content director has argued that the whole set is just SEO under new names, and the daily work looks similar: clear writing, sound structure, credible sources and a strong reputation. Treat GEO vs AEO vs SEO as one plan with three targets.
Why It Matters Now
Pew Research found that users clicked an organic result 8% of the time when an AI Overview appeared, against 15% without one. The picture is shifting, though. Seer Interactive’s data, reported by Search Engine Land, shows organic click-through on AI Overview queries rising from 1.3% in December 2025 to 2.4% in February 2026. Overviews also appear unevenly: on about 36% of informational queries and only about 5% of transactional ones.
Then there is ChatGPT. OpenAI reported 900 million weekly active users in early 2026, and India crossed 100 million weekly users in February. Your buyers are asking these tools for recommendations right now.
How to Optimise for AI Search
How to optimise for AI search comes down to habits you can start this week:
- Lead with the answer. Put a direct 40 to 60 word answer under each question heading, then expand.
- Add something quotable. Original numbers, named sources and dated facts give models a reason to cite you.
- Structure for extraction. Short paragraphs, descriptive subheadings, tables and FAQ blocks make passages easy to lift.
- Mark up your pages. Schema for Organization, Article and FAQ helps machines read your content.
- Let crawlers in. Check that robots.txt allows Googlebot, OAI-SearchBot and PerplexityBot on your key pages.
- Refresh often. Update figures, dates and examples at least once a quarter.
- Build mentions elsewhere. Reddit threads, YouTube videos, reviews and press coverage give models more places to find you.
Google AI Overviews Optimisation
Google AI Overviews optimisation starts with intent. Overviews lean toward informational queries, so how-to and explainer pages feel the pressure first, while transactional pages face far less. Write every section so it can stand alone as a passage, since Google lifts snippets rather than whole pages. Back claims with sources, show author credentials and keep your brand details consistent across your site and your Google Business Profile. Rankings still help, though they do not guarantee a citation.
How to Optimise Content for ChatGPT
To optimise content for ChatGPT, write the way people ask. Prompts run long and sound conversational, so build pages around full questions such as “which CRM suits a 20-person clinic in Hyderabad?” Include comparison tables, pricing context and a plain statement of who you serve. Use the same brand name and one-line description everywhere you appear, so the model sees a consistent picture.
Measure and Adjust
Pick 20 prompts your buyers actually use. Test them monthly in ChatGPT, Gemini, Perplexity and Google AI Mode, and log whether you are cited and how you are described. Watch impressions and clicks on informational pages in Search Console too. AI search optimisation is a long game, so judge three-month trends before changing course.
