SEO, AEO and GEO: what is the difference?

SEO earns a place in Google's results, AEO earns the quoted answer at the top, and GEO earns a mention from an AI assistant, all from one programme.

Search engine optimisation earns a business a place in the list of results Google shows for a search. Answer engine optimisation earns it the quoted answer at the top, the snippet or overview that answers the question directly and names a source. Generative engine optimisation earns it a mention when someone asks ChatGPT, Gemini or Perplexity for a recommendation. The three overlap heavily and the industry has not settled their boundaries, so treat them as three places a buyer might meet you rather than three services to buy separately.

What each one actually means

SEO is the oldest and the best understood. Google ranks pages; your page appears in the list; a buyer clicks. It is measured in positions, clicks and the enquiries those clicks produce.

AEO is about the answer box. When someone types "how much does a dental implant cost in Bengaluru", Google increasingly answers at the top of the page, quoting one source. To be that source you need a page that states the answer plainly in its first two sentences, in the words the question used.

GEO is the newest and the least settled. An assistant asked "who does sales training for manufacturers in Karnataka" composes an answer from what it can find and verify. So GEO is about being easy to find and easy to check. Nobody controls the assistant's choice; you can only make yourself the easiest business to confirm.

Read across the rows and the overlap is obvious. A page that answers the question first, on a site whose identity is consistent everywhere, with a named expert and real proof, does well on all three.

One programme for a small business

The mistake is buying three retainers. The work is one programme with four layers.

  1. Foundation. The site loads fast on a phone and Google can crawl it. The business name, address and phone are identical on the website, the Google Business Profile, IndiaMART, JustDial and every directory that lists you. Assistants cross-check these; a mismatch costs the mention.
  2. Pages. One page per thing you sell, named for the question it answers. For example, a Peenya fabrication shop has a page for laser cutting of stainless steel, with the thickness range, the machines and the lead time. It names a contact, not a generic "Services" page with eight bullet points.
  3. Content. Articles that answer the questions buyers ask before they call, in the buyer's words, with the answer in the first paragraph. That paragraph is what the answer box quotes and what the assistant paraphrases.
  4. Evidence. Named people with roles, real customer names where permitted, case studies with what was done, and reviews that are answered. Evidence is what separates a page an assistant will cite from one it will not.

Then a routine, once a month: check positions, and check which questions Google now answers with your page. Ask the two or three assistants your buyers use the same questions, and record the result.

What to prioritise, by kind of business

A local service business, a clinic or a garage, should put the Google Business Profile and reviews first. Most of its buyers never get past the map result, and assistants lean heavily on profile data for "near me" questions.

A B2B manufacturer or professional firm should put service pages first. Its buyers ask specific questions, compare in detail, and want a named person. The assistant will quote the page that answers the specific question; it will not quote a brochure.

A retailer with a large catalogue should fix the technical foundation first. Thousands of product pages with duplicate titles and slow loads will not rank, and no amount of answer-writing fixes a crawl problem.

The mistakes we see most

Buying AEO or GEO as a separate service from a separate vendor, so three people edit the same pages with different aims. Using tricks, such as hidden question lists and stuffed FAQs, which assistants discount quickly. Abandoning SEO because "AI changes everything", when the assistant reads the same index. Skipping measurement, so nobody knows which surface produced the enquiry.

What to do next

Pick the ten questions your buyers ask most on the phone. Write them down. Check whether your site answers each one on a page of its own, in the first paragraph. Where it does not, that is the work, and it serves all three surfaces at once. If you want us to run that check with you and score the gaps, tell us what you need.

Questions

Questions owners ask.

Do I need to buy separate AEO and GEO services?
No. The same foundations serve all three: a technically sound site, a page per thing you sell that answers the question directly, consistent business details everywhere, and real proof. Anyone selling AEO or GEO as a separate retainer is selling you the same work twice.
Is SEO still worth doing now that AI answers questions?
Yes. AI assistants draw on the same pages Google indexes, and buyers still click through to check a business before they call. A business invisible on Google is invisible to the assistant too.
How does an AI assistant decide which business to mention?
From what it can verify: a clear description of what you do and where, the same name, address and phone everywhere, named people, and pages that answer specific questions rather than general ones. It cannot mention what it cannot find or confirm.
Can GEO be measured?
Partly. You can ask the assistants your buyers use the questions your buyers ask, monthly, and record whether you are mentioned and what is said. Referral traffic from assistants shows in analytics. It is a routine, not a dashboard.

Where this fits

Three pieces of sales work, in this order.

This work sits inside sales process design, at stage 1, prospecting and lead generation. The audit comes before it, and sales management keeps it running.

  1. Step 1

    Sales audit

    Find where deals are being lost and what to fix first.

    Start here if you cannot say where orders are lost.

  2. Step 2 · you are here

    Sales process design

    One written way to sell, from first enquiry to repeat order.

    Start here if every salesperson sells differently.

  3. Step 3

    Sales management

    A target, a review routine and someone who owns the number.

    Start here if the team has targets and no routine.
