Search has changed shape. Google's AI Overviews and AI Mode, ChatGPT search and Perplexity all answer the question directly and cite a few websites underneath. If your site is not among those citations, the click never reaches you — even if you rank on page one in the classic results.
This is generative engine optimisation, or GEO. It is not a replacement for SEO; it is a layer on top of good SEO that makes your content easy for a machine to understand, trust and quote. Below is the practical checklist we apply to client sites.
How AI answers choose their sources
Generative engines run a search first, then pick the pages that answer the question most directly, carry the strongest trust signals (author, organisation, dates, real experience) and are easiest to extract from. Three properties decide it: a clear answer near the top of the page, evidence of expertise, and technical accessibility.
Generic content that says what every other site says is rarely cited. Specific content with numbers, steps, criteria and first-hand examples is. The engine is looking for the most quotable, most credible passage — write that passage on purpose.
Content checklist
Give every page one clear question and answer it in the first two or three sentences; put the detail afterwards. Use question-shaped headings ('How long does an e-commerce site take?') with a self-contained answer under each. Add an FAQ block marked up with FAQPage structured data. Replace vague claims with specifics: '3–5 business days' beats 'fast'.
Show experience: case results, before-and-after numbers, decisions you made and why. Keep visible publish and update dates — a 2021 guide is not quoted in 2026. Build topic clusters: a pillar page linked to focused articles tells both Google and the AI engines that you are an authority on the subject.
Technical checklist
Structured data for Organization, Service, Article, FAQPage and BreadcrumbList. Content rendered in HTML on the server — text injected only by JavaScript is invisible to several AI crawlers. Fast, mobile-first pages; Core Web Vitals in the red is still a disqualifier. Clean canonical URLs and an accurate sitemap.
Check robots.txt: if you want to be cited, allow Googlebot, Google-Extended, GPTBot, OAI-SearchBot, PerplexityBot and ClaudeBot rather than blocking them. Add an author box, an about page and consistent company details (name, address, phone) so the engine can connect the content to a real organisation.
Brand mentions count too
AI answers are built from more than your own site: reviews on your Google Business Profile, industry directories, press mentions and social profiles all contribute. Consistent company information across those sources raises the chance your name appears in answers to questions like 'reliable web agency for the Gulf market'.
For international businesses this includes local-language sources. A German case study on a German industry site does more for German AI answers than another English page on your own domain.
How to measure it
Search Console does not separate AI Overview traffic yet, but rising impressions with flat clicks usually means you appear in summaries without being clicked. Complement that with a monthly manual check: ask your ten target questions in Google AI Mode, ChatGPT and Perplexity, record which sources are cited, and track how often you appear.
Expect structured-data and content changes to be crawled within weeks; citation frequency grows over a few months as topical depth and brand signals accumulate. Our multilingual SEO guide covers how to repeat this across languages.
Key takeaways
- GEO is SEO plus machine-readability: direct answers, evidence, structured data, open crawling.
- Lead every page with a two-sentence answer; specifics get quoted, vagueness does not.
- Server-rendered HTML, FAQPage schema and an allow-list for AI crawlers are the technical minimum.
- Track citations manually each month — Search Console alone will not show you.
