What is the difference between GEO and SEO?
SEO optimizes pages to rank in search results lists. GEO (Generative Engine Optimization) optimizes a brand to be cited and recommended inside AI-generated answers from ChatGPT, Gemini, Perplexity, Claude, and Google AI Overviews.
Does GEO replace SEO?
No. SEO remains the entry ticket — crawlable, indexable, authoritative pages. GEO builds on that foundation with entity clarity, answer-shaped passages, and verifiable proof so AI engines can cite the brand.
Which should a company invest in first?
If technical SEO is broken, fix that first — AI engines are grounded in search indexes. If the site is healthy, GEO is usually the higher-leverage next investment because most competitors have not structured for AI answers yet.
How is GEO measured?
By citations, not positions: test the questions buyers ask AI engines, record whether the brand is mentioned, cited, or recommended, and track the trend monthly.
