GEO vs SEO: What Is Actually Different?
GEO and SEO share a goal - getting your website found by people who are searching. But the signals that drive each are different enough that a strong SEO strategy does not automatically translate into good GEO performance. Here is what sets them apart.
The fundamental difference
SEO optimises your website to appear in a ranked list of links when someone searches on Google or Bing. The user then decides which link to click.
GEO optimises your website to be cited as a source inside an AI-generated answer. The user reads the answer, and the AI points them to the sources it used.
This difference in format - list of links versus synthesised answer - drives almost all the differences in how each discipline works.
Signal comparison: what drives each
| Signal | SEO weight | GEO weight |
|---|---|---|
| Backlink quantity and quality | Critical | Helpful but indirect |
| Keyword usage and density | Important | Low relevance |
| Structured data / schema markup | Useful for rich results | Highly important |
| Brand mentions (without links) | Minor signal | Direct citation signal |
| Named author credentials | YMYL content only | All content |
| AI crawler access (robots.txt) | Not applicable | Foundational |
| llms.txt | Not applicable | Increasingly important |
| Page speed and Core Web Vitals | Ranking factor | Crawl efficiency signal |
| FAQPage schema | Rich result trigger | Direct citation source |
| Original data and research | Linkable asset | Primary citation driver |
Where they overlap
Many GEO improvements also benefit SEO - which is why adding GEO work to an existing SEO programme is relatively efficient. Shared foundations include:
- Content quality - clear, accurate, well-structured content ranks better in both Google and AI search
- E-E-A-T signals - expertise, authoritativeness and trustworthiness matter for both
- Technical health - fast, crawlable, well-structured pages perform better in both
- Brand authority - being a well-known, widely-mentioned brand helps in both disciplines
Where they diverge
The clearest divergences - where SEO and GEO require genuinely different work:
Link building vs brand mention building
SEO link building prioritises getting links from high-authority domains. GEO brand authority building prioritises getting your brand mentioned in credible contexts - even without a hyperlink. Press coverage, podcast appearances, industry reports citing your data, and directory listings all contribute to GEO authority.
Keyword optimisation vs answer optimisation
SEO requires targeting specific keyword phrases with appropriate density and placement. GEO requires structuring content so that AI engines can extract clear, quotable answers - regardless of keyword positioning. A GEO-optimised page gives AI engines something worth quoting; a keyword-optimised page gives Google a relevance signal.
AI-specific technical requirements
GEO has a set of technical requirements with no SEO equivalent: AI crawler access in robots.txt, llms.txt, and ensuring that your site works correctly for headless crawlers that do not execute JavaScript. These have no parallel in traditional SEO.
The practical implication
If you already do SEO well, you are not starting from zero on GEO. But you do have a specific set of gaps to address: AI crawler permissions, llms.txt, FAQPage and Article schema on content pages, and a brand authority strategy that goes beyond link building. A GEO audit will tell you exactly where those gaps are on your specific site.
