SEO vs AEO vs GEO: What Should Small Businesses Focus On?

By Neha·Published October 15, 2026

Last month you were told you need SEO. This month an agency says SEO is dead and you need AEO. Next month someone on LinkedIn will say GEO is the only thing that matters now. Each comes with a new package and a new price.

If you run a coaching centre in Kota or a catering business in Hyderabad, you do not have time to chase three sets of initials. The good news is that you do not need to. The three overlap far more than the sellers admit, and one of them is the base for the other two.

This guide explains SEO vs AEO vs GEO in plain words, shows where they really differ, and gives you a short priority list for where to spend your time.

Short answer: SEO helps your pages show up in search results. AEO helps your content get picked as a direct answer. GEO helps your business get mentioned in AI-written answers such as ChatGPT. All three depend on the same foundation: a website search engines and AI tools can read, clear facts about your business, and a good reputation elsewhere. Do the SEO basics first, write clear answers to customer questions, then make sure AI tools are not blocked. A free AI readiness check and a website audit show you where you stand on both.

What is SEO?

SEO stands for search engine optimisation. It is the work of helping your website appear, and appear high, when someone searches on Google or Bing.

For a small business it usually means:

• Making sure search engines can find and read every important page.
• Writing a clear page for each service, with a good title and description.
• A fast site that works well on phones.
• A complete Google Business Profile, the free listing that shows on Google Maps.
• Reviews, and links or mentions from other trustworthy websites.

The goal is a click: someone sees your result and visits your site or calls you. Our guide to local SEO for small business covers it in depth.

What is AEO?

AEO stands for answer engine optimisation. An "answer engine" is anything that replies with an answer instead of a list of links: the highlighted box at the top of some Google results, a voice assistant reading out a reply, or an AI chatbot.

AEO means writing your content so it is easy to lift as an answer. In practice:

• Put a real question as a heading, the way a customer would ask it: "How much does a birthday catering order for 50 people cost in Hyderabad?"
• Answer it in the first one or two sentences, then add detail.
• Keep each answer complete on its own, so it makes sense even if quoted alone.
• Add an FAQ section to key pages.

You can label those questions and answers for machines with FAQ structured data, a small block of code; the FAQ schema generator writes it for you. Be realistic: since 2023 Google shows the expandable FAQ results mainly for well-known government and health websites, so most businesses will not see dropdowns under their listing. The code still makes your answers easier for machines to read.

What is GEO?

GEO stands for generative engine optimisation. "Generative" refers to AI tools that write a fresh answer each time, such as ChatGPT, Perplexity, Gemini, Claude, and Google's AI Overviews. GEO is about making your business likely to be mentioned, described correctly or cited as a source in those answers.

The extra pieces GEO adds on top of SEO and AEO are:

• Letting AI crawlers in. AI companies use their own bots to read websites, such as OAI-SearchBot for ChatGPT search and PerplexityBot for Perplexity. If your robots.txt file blocks them, they cannot read you. The AI crawler checker shows which ones your site allows.
• Consistent facts across the web. AI tools compare sources. Your name, address and phone should match everywhere.
• Being talked about. Reviews, directory listings and mentions in local news or blogs give AI tools something to draw on.
• Optional extras like an llms.txt file, a proposed summary file for AI tools that no major AI company has confirmed using. Our guide on whether your website needs an llms.txt file covers it.

To see how your own site does on these points, the AI readiness checker gives you a score out of 100 and a plain fix list.

SEO, AEO and GEO side by side

That last row is the point of this whole article.

Why SEO is the foundation for all three

Think about how each kind of answer is built.

• Google AI Overviews draw on pages Google has indexed, meaning pages it has read and stored. Google says a page must be indexed and eligible to show in normal search before it can appear as a source. No SEO basics, no AI Overview.
• ChatGPT answers local questions largely by searching the web, using third-party search providers alongside its own crawler. If search engines barely know your site, ChatGPT has little to find.
• Answer boxes and voice answers are usually taken from pages that already rank well.

So a site that is slow, blocked, thin or missing from Google's index will struggle in all three. A site with clear service pages, correct business details, good reviews and no technical problems has most of what AEO and GEO need already.

That is why we are sceptical of anyone selling GEO as a replacement for SEO. The honest description is that GEO is SEO plus a few extra checks.

What should a small business focus on? A priority list

Work through this in order. Each step helps all three.

1. Fix what stops search engines reading your site. Run a free website audit. It reads up to 25 pages on the free plan, takes one to two minutes, and explains each problem in plain words, starting with the most important. It does not measure rankings or traffic; it shows what is getting in the way.
2. Complete your Google Business Profile. For a local business this often matters more than the website. See our Google Business Profile optimization guide.
3. Write one clear page per service. What it is, who it is for, the area you cover, the price or starting price, how to book.
4. Answer real customer questions. Add five or six FAQs to your main pages, each answered in the first sentence. This is your AEO.
5. Make your details match everywhere. Name, address and phone the same on Google, Justdial, IndiaMART, Facebook and your website.
6. Ask for reviews, steadily. A few genuine reviews every month beats a burst once a year.
7. Check AI readiness. Run the AI readiness checker. It reads your robots.txt, llms.txt, sitemap and one page, and scores eleven checks out of 100, with crawler access and clear business details weighted most. It measures readiness, not whether any AI actually mentions you.
8. Add the small extras. Business structured data, FAQ markup and, if you like, an llms.txt file from the llms.txt generator.

Notice that steps 1 to 6 are plain SEO. Only steps 7 and 8 are specific to AI, and they take an afternoon.

How to spot SEO, AEO or GEO hype

Be careful with any offer that:

• Guarantees a ranking or an AI mention. Nobody outside Google or OpenAI controls their results.
• Says SEO is dead. AI answers are built on search. The basics matter more, not less.
• Sells llms.txt as the key to ChatGPT. It is a cheap optional file with unconfirmed support.
• Promises hundreds of AI-written pages. Google treats mass-produced, low-value content as spam. Our guide on what ChatGPT can and cannot do for SEO explains where AI genuinely helps.
• Cannot explain the work in plain words. If they cannot tell you what they will change on your site, they may not change much.

Your next step

Forget the initials for a moment. This week, run a free website audit and fix the top item it finds. Next week, add clear answers to your five most common customer questions on your main service page. The week after, run the AI readiness checker and fix anything red. That is SEO, AEO and GEO covered, in the right order, without paying for three packages. If you want a structured way to go through your whole site, our guide on checking your website's SEO for free walks you through it.

Frequently asked questions

Is GEO replacing SEO?

No. AI tools like ChatGPT and Google AI Overviews mostly draw on what search engines already know, so a site that does badly in normal search usually does badly in AI answers too. GEO adds a few checks on top, such as letting AI crawlers in and keeping your facts consistent, but it does not replace the basics.

Do I need to hire separate people for SEO, AEO and GEO?

No. For a small business, it is one job done by one person or agency. The same work, clear pages, correct details, good reviews and a site with no technical problems, serves all three. Be wary of anyone who prices them as three separate services.

What is the cheapest way to start?

Run a free website audit and a free AI readiness check, fix the top items on each, complete your Google Business Profile and add answers to common customer questions on your main pages. None of this costs money, only a few hours of time.

How do I know if AEO or GEO is working?

For search, Google Search Console shows clicks and positions. For AI answers there is no official report, so ask ChatGPT, Perplexity and Gemini the questions your customers ask, once a month, and note whether you appear and whether the details are right. Look for a pattern over a few months, not a single result.

Is FAQ schema still worth adding?

It is quick to add and makes your questions and answers easier for machines to read. But since 2023 Google shows FAQ rich results mainly for well-known government and health sites, so do not expect extra dropdowns under your listing. Add it to pages that genuinely show those questions, and keep the code matching the page.
