GEO vs SEO: What's the Difference?
GEO gets you cited in AI answers; SEO ranks you in search results. Here is the difference, how they overlap, and which your business needs.
SEO optimizes to rank your pages in search results; GEO (generative engine optimization) optimizes to get your brand cited inside AI answers from ChatGPT, Perplexity, and Google's AI. They overlap and reinforce each other, but they are different jobs, and most B2B companies now need both. Corbelix is a generative engine optimization agency for B2B SaaS and established brands.
Here is the practical difference, where they overlap, and how to decide where to invest.
What SEO does
SEO earns rankings in traditional search results through relevant content, technical health, and links. The unit of success is a ranked page that drives clicks. It remains valuable, because search still sends significant traffic and because the pages that rank well often become sources AI models read.
What GEO does
GEO earns citations inside AI-generated answers. The unit of success is being part of the synthesized response a model gives when a buyer asks, which depends on clarity, consistent entity data, and corroboration across trusted sources. For the full mechanics, see our guide to generative engine optimization.
The key differences
Both shape visibility, but they optimize for different surfaces and success metrics.
- Target: SEO ranks a page; GEO gets cited in an answer.
- Signal: SEO leans on links and rankings; GEO leans on corroboration and clarity.
- Surface: SEO lives in search results; GEO lives in ChatGPT, Perplexity, and AI overviews.
- Metric: SEO tracks rankings and traffic; GEO tracks citations and share of voice.
Which do you need?
For most B2B companies, the answer is both, run as one system. SEO captures buyers who still search, and GEO captures the growing share who ask an AI first. Neglecting either leaves a gap in the buying journey. Our B2B SaaS SEO and GEO playbook shows how to sequence them, and what a GEO agency actually does explains the GEO side in depth.

- SEO leans on links and rankings; GEO leans on corroboration and clarity.
- They overlap: pages that rank well often become sources AI models cite.
- Most B2B companies need both, run as one system, not one or the other.
