What Is the Difference Between SEO and GEO?
SEO ranks pages in Google. GEO gets you cited in AI answers. 93.67% of AI citations come from top-10 results, so you need both.
SEO (Search Engine Optimisation) ranks your pages in Google's blue links. GEO (Generative Engine Optimisation) gets your business cited in AI-generated answers from ChatGPT, Gemini, Perplexity, and AI Overviews. 93.67% of AI citations come from pages already in the top 10. You need both. SEO builds the foundation. GEO gets you cited.
SEO vs GEO: the key differences
| Factor | SEO | GEO |
|---|---|---|
| Goal | Rank in blue links | Get cited in AI answers |
| Output | Page 1 position | Named citation in AI response |
| Ranking signals | Backlinks, content, technical | Entity authority, content clarity, schema |
| Traffic model | User clicks through to site | User may or may not click - but trusts the citation |
| Conversion rate | 2.1% average | 27% average |
| Measurement | Rankings, clicks, impressions | Citation frequency, brand mentions, AI referrals |
Why SEO still matters for AI visibility
A common myth says GEO replaces SEO. The data says otherwise. 93.67% of sources cited by AI models already rank in the top 10. AI platforms use organic ranking as a proxy for authority. If Google trusts you enough to rank you, AI models are more likely to cite you.
Abandoning SEO for GEO would be counterproductive. The strongest AI visibility strategy builds on solid SEO and adds GEO-specific work on top.
What GEO adds beyond SEO
GEO introduces requirements that traditional SEO does not cover:
- AI crawler access - allowing GPTBot, ClaudeBot, and PerplexityBot in your robots.txt
- Answer-first content - lead with direct, quotable answers instead of building up to conclusions
- Entity-based authority - brand mentions across the web matter more than individual backlinks
- Schema markup - structured data helps AI understand your content's meaning, not just its text
- Multi-platform presence - Bing matters for ChatGPT, YouTube for Gemini, and Wikipedia for most platforms
The overlap: what works for both
Some optimisation serves both SEO and GEO. Clear H1 tags, well-structured content, topical authority, E-E-A-T signals, and fast page speed all help with both. If you do SEO well, you are already 60-70% of the way to AI visibility. The remaining 30-40% is GEO-specific work.
