Short answer: SEO (search engine optimization) helps your website rank in Google and Bing results. GEO (generative engine optimization) helps AI assistants like ChatGPT, Gemini, Perplexity and Google AI Overviews mention and recommend your business in their answers. Most businesses need both, because AI tools rely heavily on the same trusted, well-structured websites that rank well.
The key differences
| SEO | GEO | |
|---|---|---|
| Where you appear | Google and Bing search results | Answers from ChatGPT, Gemini, Perplexity, AI Overviews |
| What you win | A click to your website | Being named and recommended |
| Main signals | Keywords, backlinks, speed, Google Business Profile | Clear facts, structured data, reviews, mentions on trusted sites |
| How you measure | Rankings, traffic, enquiries | How often AI names you for key questions |
Where they overlap
- A fast, well-structured website. Both search engines and AI tools read your pages.
- Clear answers. A page that answers the question in its first two lines helps a Google snippet and an AI answer.
- Reviews and reputation. Google ranks well-reviewed businesses higher, and AI assistants repeat what reviews say.
- Consistent business details. The same name, phone number and address everywhere builds trust with both.
What GEO adds on top of SEO
- Fact-first content. Prices, locations, services and clients written as plain facts AI can quote.
- Structured data. Schema that tells machines exactly who you are and what you offer.
- llms.txt. A simple summary file written for AI assistants.
- Bing visibility. ChatGPT search relies largely on Bing, so Bing Webmaster Tools and IndexNow matter.
- Mentions on trusted sites. Directories, Reddit and Quora threads, LinkedIn articles and client case studies.
Where should a small business start?
- Fix the basics: a fast website, Google Search Console, Bing Webmaster Tools and a Google Business Profile.
- Write clear service pages with prices and FAQs.
- Collect real reviews from happy clients.
- Add structured data and an llms.txt file.
- Track 10 to 20 questions your customers ask AI tools, every month.
