SEO vs AEO vs GEO: what's the difference?
SEO (search engine optimization) is getting your pages to rank in Google's list of links and earning the click. AEO (answer engine optimization) and GEO (generative engine optimization) both mean getting your business named or cited inside answers written by AI tools such as ChatGPT, Gemini, Perplexity and Google's AI Overviews, and the two terms overlap so much that many writers use them as synonyms.
| Goal | Where you show up | How you measure it | |
|---|---|---|---|
| SEO | Rank pages and earn the click | Google and Bing lists of links | Search Console clicks, impressions and position |
| AEO | Be the answer an AI or search feature gives | ChatGPT, Gemini, Perplexity, AI Overviews, featured snippets | Asking AI tools your buyers' questions; AI impressions in Search Console |
| GEO | Be cited or mentioned in AI-generated answers | The same AI answers, as a named brand or a linked source | Brand mention checks across AI tools, repeated over time |
This guide is for founders, D2C brands, clinics, CA firms and other small businesses in India who keep seeing three acronyms and want to know which one to pick. The short answer is that you don't pick one: SEO is the base, and AEO and GEO build on it, so a business that wants to be found needs all three. This post focuses on the terms and where GEO came from. For the deeper AEO and SEO comparison, including how to rank in ChatGPT, read our AEO vs SEO guide.
What are SEO, AEO and GEO?
SEO is the work of making your pages easy for search engines to crawl, understand and rank. It covers technical health (pages load and get indexed), content that matches what people search for, on-page basics such as titles and headings, and links from other sites. Success is a good position and a click.
AEO was first used mostly for winning the direct-answer spots in search: featured snippets, People Also Ask boxes and voice assistant replies. Today most articles use it for answer engines, meaning tools that reply with a written answer instead of a list of links. HubSpot, for one, defines it as improving how often and how accurately your brand appears in AI-generated answers, and says it does not replace SEO.
GEO is the term that came out of research. A 2023 paper titled "GEO: Generative Engine Optimization" described a way of changing a page so a generative engine is more likely to cite it. It reported that some methods raised visibility in generated answers by up to 40% on the authors' own benchmark, and that how well each method worked varied by domain (arXiv 2311.09735). The paper measured visibility inside generated responses. It did not measure traffic or sales, so don't read it as a promise of either.
Is AI SEO the same thing as GEO?
Often, yes, though nobody enforces the names. People say "AI SEO", "GEO", "AEO" and "LLM SEO" loosely, for overlapping things: making your site and brand show up in AI-written answers.
GEO has the clearest paper trail, because it comes from the 2023 research paper above. AEO has the older, narrower history in snippets and voice answers. "AI SEO" and "LLM SEO" are plain-English labels with no single source. For practical work, the labels matter less than the checklist underneath them, which is mostly the same.
AEO vs GEO: where is the line?
The two terms point at the same target: a written answer from an AI tool that names your business or links to your page. The line between them is blurry.
Where people do draw a line, it usually goes like this. AEO is the broader or older term, covering short direct answers as well as AI assistants. GEO is the narrower one, aimed at generative AI tools and at being cited as a source. Others reverse it or treat the two as identical. You will see both patterns in the top articles for these searches, and none of them is an official standard.
For a small business, the work does not split cleanly. Writing a clear answer near the top of a page helps a featured snippet and an AI citation alike. Getting your brand mentioned on sites an AI tool reads helps whichever name you prefer. Pick one term for your own planning and stick to it.
Is AEO better than SEO, or built on it?
No, because AEO builds on SEO instead of replacing it. A page that Google has not indexed cannot be shown as a link in AI Overviews or AI Mode either. Google's own documentation says there are no additional requirements to appear in these AI features, and that you do not need special files, markup or schema for them. The page has to be indexed and eligible to show with a snippet (Google Search Central).
Other AI tools run their own crawlers, though. OpenAI says a site that blocks its OAI-SearchBot will not be shown in ChatGPT search answers, although it may still appear as a plain navigational link. Blocking GPTBot is a separate setting that only opts your content out of training (OpenAI).
The other AEO: agentic engine optimization
The initials AEO have a second meaning. Agentic engine optimization is about making your site, documentation or product usable by AI agents, which do not just answer a question but open your site and act on it: reading docs, calling an API, booking or buying. The work is different from answer engine optimization: clear structure, machine-readable content and predictable pages that an agent can parse.
If you came here for that meaning, our guide to agentic engine optimization covers it. In the rest of this post, AEO means answer engine optimization.
What should a small business in India do first?
Start with SEO, in this order:
- Connect Google Search Console and check that your main pages are indexed.
- Make sure your robots.txt and firewall allow AI search crawlers such as OAI-SearchBot and PerplexityBot, and that Googlebot can reach your pages. Qelvra's free AI Visibility Checker tests this.
- Rewrite your top pages so the first two sentences say what you are, who it is for and the key facts.
- Repeat the checks every month.
The full step-by-step list is in the AEO vs SEO guide.
How do you measure SEO, AEO and GEO?
SEO. Google Search Console remains the source. Clicks, impressions and average position tell you how your pages perform in Google.
AEO and GEO in Google. Since June 2026, Search Console has a dedicated generative AI performance report showing impressions of your pages in AI Overviews, AI Mode and Discover's AI features. Google says it reached all websites by 31 August 2026. The same traffic also stays in your Web search totals (Google Search Central blog).
AEO and GEO in other AI tools. There is no ranking position to look up. Write down 10 to 20 questions your buyers ask, run them in ChatGPT and Gemini, and note whether you are named, who is named instead and which sites are cited. Answers change from one run to the next, so repeat the check monthly and look at the pattern, not a single result. Visits from chatgpt.com, perplexity.ai or gemini.google.com in your analytics referral reports are another signal.
Where Qelvra fits
Since you need all three, here is how Qelvra, an AI SEO agent for Indian businesses, maps to each. For a plain-English walkthrough, see what an AI SEO agent is.
- SEO. You add your site and connect Search Console, then ask in plain English, Hindi or Hinglish: "What should I fix first?". The agent reads your pages and Search Console data, crawls the site, prioritises fixes and gives you a plan or a finished draft. On paid plans it also tracks the keywords you choose every week. Search Console access is read-only, and once you connect WordPress or Shopify, articles can publish there after you approve them.
- AEO and GEO. The free AI Visibility Checker tests whether AI crawlers can reach your site. The free Brand Explorer check asks ChatGPT a few of your buyers' questions and shows whether it names you. Full scans ask ChatGPT and Gemini, compare your scans once you have two or more, and use credits; they are not included in Starter (see the Brand Explorer guide). From what the answers show, the agent tells you what to fix and where to get mentioned. Nobody can guarantee an AI tool will name you, and Qelvra doesn't promise it.
It is one agent for all of this, priced in rupees (paid by UPI, card or netbanking). There is a free plan (20 credits to start, then 3 a day), a 7-day trial with no card needed, and paid plans from ₹4,299 a month. Qelvra also has other free AI SEO tools. See pricing.

Frequently asked questions
Is AEO better than SEO?
No. AEO builds on SEO instead of replacing it. Google says a page must be indexed and eligible for a snippet to appear in AI Overviews and AI Mode, and that no special optimization is needed beyond that. Do SEO first, then add the AI-specific checks.
Is AI SEO called GEO?
Often, but not always. People use "AI SEO", "GEO", "AEO" and "LLM SEO" loosely for overlapping work: getting visible in AI-written answers. GEO comes from a 2023 research paper on generative engine optimization, so it is the term with the clearest origin.
What is the difference between AEO and GEO?
There is no agreed line. AEO is usually the broader or older term, covering direct answers in search and AI assistants. GEO is usually used for generative AI tools and being cited as a source. Many articles treat them as the same thing, and the practical work is nearly identical.
Do I need GEO if I already do SEO?
You need a few extra checks, not a second program. Good SEO gets your pages indexed, which Google's AI features require. On top of that, confirm that robots.txt allows OAI-SearchBot and PerplexityBot, and ask ChatGPT and Gemini your buyers' questions to see whether you are named.
Does Google Search Console show AI Overviews traffic?
Yes. Google added a dedicated generative AI performance report to Search Console in June 2026, showing impressions in AI Overviews, AI Mode and Discover's AI features, and says it reached all websites by 31 August 2026. The same traffic also stays in your Web search totals.
Which should a small business in India start with?
SEO. Get your key pages indexed, then allow AI crawlers and rewrite your top pages answer-first. A free check such as the AI Visibility Checker shows whether AI crawlers can read your site today.
