GEO and SEO: why you still need both
The short version: GEO doesn't replace SEO — it's largely built on top of it. Roughly two-thirds of the work is shared; the rest is a distinct layer.
What they share
The answer engines that matter most for GEO — Google's AI Overviews, Perplexity, ChatGPT search, Gemini — retrieve from much the same web that SEO has always served. So the foundations overlap almost entirely:
- Technical crawlability and clean site structure.
- Structured data and schema.
- Domain authority and quality content.
- Presence on trusted third-party sources.
If a firm's SEO foundation is broken, GEO usually can't work at all. Strong SEO is the accelerant.
Where they diverge
- The goal. SEO wants the click to your site. GEO wants you cited or recommended in the answer — often with no click at all. Different measure of success.
- The unit. SEO is keyword- and page-level on Google. GEO is entity- and answer-level, and it spans several engines, not one.
- The weighting. Models synthesise consensus, so community presence, review sentiment and "what the whole web says about you" matter more than ranking first on a single page.
- The content shape. GEO rewards clear, extractable, factual statements; SEO rewards comprehensive depth. They're converging, but they aren't identical.
How to invest
Lead with GEO — it's where the new ground and the advantage are. But deliver the SEO foundation as part of it, because GEO depends on it. In practice, a visibility audit almost always surfaces broken technical SEO and thin structured data; fixing that is the GEO work. Treat SEO as the plumbing you do because the new channel won't run without it.
The incumbents are coming the other way — bolting GEO onto SEO. Your edge is being the specialist who started from the new channel.
