Generative engine optimization (GEO) is the work of making your content easy for AI systems such as ChatGPT, Perplexity, Gemini and Google AI Overviews to find, understand and cite when they write an answer. It is not a separate discipline from SEO. Most of it is good SEO done carefully, plus a few habits that matter more when a machine summarises your page instead of a person clicking it.
What do GEO, AEO and LLM SEO mean?
They are different names for roughly the same goal: being used as a source in AI-generated answers. None of them is an official standard, and people use them loosely.
| Term | Usual meaning |
|---|---|
| GEO (generative engine optimization) | Optimising for search tools that generate answers, such as AI Overviews and Perplexity. The name comes from a 2023 academic paper. |
| AEO (answer engine optimization) | An older term from the era of featured snippets and voice assistants, now applied to AI answers too. |
| LLM SEO or AI SEO | Informal labels for getting a brand mentioned or cited by large language model chatbots. |
If an agency sells GEO as something entirely new, ask what they will actually change on your site. The answer should sound very familiar.
How is GEO different from SEO?
The main difference is the outcome you measure. Classic SEO aims for a ranked link and a click. GEO aims for a mention or a citation inside an answer, which may or may not send a visit.
- Unit of value. SEO ranks whole pages. AI answers often lift a single passage, so each section of a page needs to stand on its own.
- Who decides. Search results are ordered by ranking systems. AI answers are written by a model that picks and combines sources, so wording and clarity of individual facts matter more.
- Off-site signals. For questions like "best MBA coaching in Bengaluru", assistants lean heavily on reviews, comparison articles and forums. What others say about you can matter as much as your own page.
- Measurement. There is no Search Console for ChatGPT. You track visibility by asking assistants real questions over time.
Where does GEO overlap with SEO?
Almost everywhere. Google says pages appear in AI Overviews through its normal Search index and ranking systems, and several other assistants search the web through Bing or their own crawlers. If a page cannot be crawled, indexed or trusted, no GEO trick will rescue it.
The shared foundations are crawl access, fast and indexable pages, clear titles and headings, accurate structured data, and content written by people who know the subject. Google's guidance on AI features and your website says there are no extra requirements beyond normal Search eligibility.
What actually helps you get cited by AI?
The changes that help are concrete and easy to check. Start with access, then structure, then reputation.
- Let the crawlers in. Check robots.txt and your CDN or firewall for blocked AI user agents such as OAI-SearchBot and PerplexityBot. Many sites block them by accident.
- Answer first. Put a direct answer under each question heading, then the detail. See how to write content AI assistants quote.
- Be specific. Fees in ₹, course duration, batch sizes, dates and named sources are easier to quote than vague claims.
- Make your brand unambiguous. Use one consistent name, Organization markup and links to your official profiles. See entity SEO.
- Show who wrote it. Named authors with relevant experience and a visible updated date help readers and systems judge reliability.
- Earn mentions elsewhere. Reviews, directory listings, news coverage and genuine forum discussion feed the answers to "best" and "which" questions.
What does not help?
Some popular tactics have no public evidence behind them or are risky. Avoid spending time on them.
- Hidden text or prompts aimed at AI models. This is spam and can be treated as such by Google.
- Keyword-stuffed FAQ blocks that repeat the same question in ten ways.
- Mass-produced AI pages with no original information. Google's spam policies cover scaled content abuse regardless of how it is made.
- Expecting a file such as llms.txt or a special schema type to guarantee citations. Neither is required by Google for AI Overviews.
Common mistakes
- Treating GEO as a replacement for SEO and neglecting indexing problems.
- Blocking all AI bots in one rule, then wondering why assistants never cite you.
- Judging success from one chat session. AI answers vary between runs, users and locations.
- Rewriting every page at once instead of starting with the ten pages that answer your customers' most common questions.
