SEO improves crawling, indexing, relevance, search presentation, and clicks. GEO additionally asks whether a generative system can identify the entity, extract a direct answer, verify evidence, and cite the source accurately. Both depend on sound technical SEO and useful content; no special tag guarantees citation.
Shared foundations and different emphasis
| Dimension | SEO | GEO |
|---|---|---|
| Foundation | Crawling, indexing, page experience | Depends on the same foundation |
| Content | Search intent, titles, internal links | Direct answers, definitions, verifiable evidence |
| Entity | Consistent brand and topic | Clear company, brand, author, service, and channel relationships |
| Measurement | Impressions, clicks, rankings, conversions | Mentions, cited pages, referrals, answer accuracy, conversions |
Complete technical and entity foundations
Put important information in visible text, allow target crawlers, and connect pages with canonical URLs, hreflang, sitemaps, internal links, and structured data that matches visible content.
Keep the company name, brand, domain, contact details, and service scope consistent across official channels.
Create verifiable evidence pages
Answer real buyer questions: what it is, who it fits, how it works, how options differ, and where the limits are. Cite important claims and describe the method and scope of first-party evidence. Do not invent customer results.
Measure GEO with a repeatable baseline
Use a fixed prompt set on a fixed cadence. Record brand mentions, official-site citations, cited URLs, and answer accuracy, then compare them with search exposure, AI referrals, and conversions.
One answer is not a stable ranking; generative results vary.
Frequently asked questions
Do we need llms.txt?
There is no evidence that it is required for Google generative search or ChatGPT search. Crawlability, index eligibility, and content quality matter more.
Can GEO guarantee a ChatGPT citation?
No. It can improve discoverability and verifiability, but the platform and query context determine each answer.
Must GPTBot be allowed for ChatGPT search?
No. OpenAI controls OAI-SearchBot for search separately from GPTBot for potential model training.
