What is generative engine optimisation (GEO)?
Generative engine optimisation (GEO) is the work of making a website easy for AI assistants to read, trust and quote. Where SEO aims for a ranking, GEO aims for a citation: your business named, and ideally linked, inside an answer from ChatGPT, Perplexity, Claude or Google's AI Overviews.
Is GEO different from SEO?
GEO is SEO plus three things. Google states that a page needs no extra technical steps to appear in AI Overviews beyond being indexed and eligible for a snippet, so strong SEO is the foundation. GEO then adds: making sure non-Google assistants can read the site at all, writing in a shape that survives being quoted, and building presence on the off-site sources assistants rely on.
What does Koseti change on a website for GEO?
Koseti makes four kinds of change: every answer moved into the server-rendered HTML, key pages rewritten answer-first with question-shaped headings, comparison and evidence content added with named sources, and off-site profiles built and linked to the site as one consistent business.
What does Koseti not sell?
Koseti does not sell llms.txt files, FAQ schema or "AI visibility scores" as fixes for AI search. Controlled tests have found no citation uplift from adding schema alone, and most llms.txt files have never been requested by an AI crawler. Koseti spends that budget on content and access, which the evidence does support.
How do you measure GEO?
Koseti measures GEO with a fixed prompt panel of 20 buyer questions, run monthly across ChatGPT, Perplexity, Claude and Google AI Mode, recording whether you are cited with a link or only mentioned. Alongside it, Search Console's generative AI report shows how often your pages appear in Google's AI features.
Has Koseti done this for a real business?
Yes. Koseti built and wrote the site for Voco, an AI front office for UK businesses, answer-first throughout: question-shaped headings, a plain-English definition of an AI front office, sourced comparison tables and an "ask an AI assistant about Voco" section. Between June and September 2026, Voco's monthly search clicks quadrupled.
How much does GEO cost?
GEO is included in every Koseti SEO retainer rather than sold as an extra. Retainers are scoped to your market and goals, typically from a few hundred pounds a month for local businesses up to several thousand for competitive national terms.
