Comparison
GEO vs SEO: What's the Difference?
The short answer: SEO optimises for Google rankings. GEO optimises for AI-generated answers. They target different systems, require different techniques, and measure success differently. Applying SEO logic to GEO work produces no results.
Full comparison
Can you do both SEO and GEO at the same time?
Yes — but they require separate workstreams. Some activities overlap (semantic content structure, for example, helps both crawlers and language models). But the majority of GEO work has no SEO equivalent, and vice versa.
A brand can rank on page one of Google and have zero AI citations. A brand with limited domain authority can appear frequently in AI answers if its content is well-structured and corroborated by third-party sources. The ranking signals are independent.
Why agencies need both
AI search usage is growing fast. ChatGPT now handles over a billion queries per week. Perplexity is growing as a default research tool. Google AI Overviews appear on a significant proportion of informational queries. Clients who are invisible in AI answers are losing discovery to competitors who are not.
Agencies that offer only SEO are leaving a measurable visibility gap uncovered. GEO fills that gap — and because few agencies currently offer it, early adoption creates a competitive differentiator for your agency before the market catches up.
