GEO vs SEO and how they work together

Search engine optimization is the work of getting pages crawled, indexed and ranked in search results. You research what people search for, publish pages that answer it well, keep the site technically healthy and earn links that signal authority.

The scoreboard is familiar: positions, impressions and clicks. Because the result is a list, several brands can win the same query, and a page in position five still gets some traffic.

SEO is also the entry ticket for Google's AI features. To be a supporting link in AI Overviews or AI Mode, a page must be indexed and eligible to show with a snippet, and there are no extra requirements beyond that (Google).

Generative engine optimization is the work of getting your content used, cited and named when an AI system writes the answer. That covers Google AI Overviews and AI Mode, plus assistants that search the web, such as ChatGPT, Perplexity, Gemini and Claude. For the full definition and the research behind the term, see the generative engine optimization page.

GEO matters because much research now ends on the results page. SparkToro found that 68.01% of Google searches ended without a click in January to April 2026, based on Similarweb data (SparkToro, June 2026). When a person reads the answer instead of visiting pages, the brands named in that answer get the attention.

The scoreboard changes shape. Instead of a position, you track whether the answer mentions you, whether it links to your page, and whether it describes you correctly.

AI engines pick sources by searching first and writing second. Google says its generative AI features are rooted in its core Search ranking and quality systems, and ground answers in content those systems find (Google Search Central). There is a ranking system underneath; it is the one SEO already works with.

Fan-out widens the pool. Because the model runs related searches, a page that answers one sub-question well can be cited even when it does not rank for the original query. Google's own example turns "how to fix a lawn that's full of weeds" into searches for the best herbicides for lawns, removing weeds without chemicals and preventing weeds in a lawn.

Google's advice for AI search matches its SEO advice: unique content that is not a commodity, a good page experience, crawl and index access, and structured data that matches visible content (Google, May 2025). It also warns that seeking inauthentic mentions across the web is not as helpful as it might seem, and that no third-party tool has access to its internal ranking or AI systems.
