From ten blue links to AI answers

Lesson 1 of 8 · 25 min · part of the AI SEO & GEO Specialist certification

For twenty years, search meant a ranked list of links. Today a growing share of queries is answered directly: Google's AI Overviews and AI Mode, ChatGPT search, Perplexity, Microsoft Copilot and Claude all write an answer and cite a handful of sources.

SEO (search engine optimization) earns you a position in the ranked results. GEO (generative engine optimization) earns you a place inside the answer — as a cited source. The two overlap heavily: AI answer engines still retrieve pages through a search index, so a page that cannot be crawled or ranked rarely gets cited.

• Crawl — a bot fetches your page. If robots.txt blocks it, or the content needs JavaScript the bot doesn't run, nothing else matters.
• Index — the page is parsed and stored. Duplicate, thin or noindex pages drop out here.
• Rank / retrieve — for a query, the engine picks the most relevant, trustworthy pages.
• Answer & cite (AI engines) — a model reads the retrieved passages, writes an answer and links the sources it used.
