SEO vs AEO vs GEO: what each means for a small business

The three terms in one table

SEO: being found in Google's results

Search engine optimisation is the work of helping search engines find, understand and rank your pages. Google's own starter guide boils it down to a few things: make sure Google can find your pages, write content people find useful, and use clear titles, descriptions and links.

For a small business, most SEO wins are unglamorous:

• Each service you sell has its own page, with a title that says what it is and where you are.
• Your site loads quickly on a phone and has no pages accidentally blocked from Google.
• Your business name, address and phone number are the same on your site, your Google Business Profile and the directories you are listed on.
• Pages answer what a customer actually asks before they call: price ranges, timings, what to expect.

AEO: being the answer, not just a result

Answer engine optimisation grew out of featured snippets and voice search. When someone asks "how long does a root canal take", Google often shows a short answer pulled from one page above the regular results. AEO is about writing so that your page is the one it pulls from.

What helps:

1. 1Put the question as a heading, in the words customers use.
2. 2Answer it in the first two or three sentences under that heading, before any detail.
3. 3Then give the detail: steps, a short list, or a small table.
4. 4Keep one page focused on one topic, so it is clear what the page answers.

There is no special markup that guarantees an answer box. Google picks the passage it thinks answers best.

GEO: being named by AI assistants

Generative engine optimisation is newer. When someone asks ChatGPT or Gemini "which dentist in Indiranagar is good for implants", the assistant writes an answer and may name a few businesses. GEO is the work of making sure yours is one of them, and that what the assistant says about you is right.

AI assistants build answers from two places: what they learned in training, and pages they read live from search results. That second part is why the basics still matter. Google states plainly that to appear as a supporting link in AI Overviews or AI Mode, a page needs to be indexed and eligible to show in Google Search with a snippet, and that there are no extra requirements.

What helps with GEO specifically:

• Let the AI crawlers in. Assistants like ChatGPT and Perplexity use their own crawlers. If your robots.txt or your security settings block them, they cannot read your pages when answering. Each company documents its crawlers publicly.
• Say what you are, plainly and consistently. Your business name, what you do, where, for whom and your prices, written the same way on your site, your Google Business Profile and listings.
• Be mentioned elsewhere. Assistants trust businesses that other reputable sites talk about: local news, associations, well-known directories, real reviews.
• Answer the questions they get asked. If people ask assistants "what does a dental implant cost in Bengaluru", a clear page on your site that answers it gives the assistant something to cite.

Do you need all three?

Yes, but in order. A business with a slow site that Google can't index will not be quoted by anyone. Start with SEO basics, then shape your key pages to answer questions (AEO), then work on being consistently described and mentioned across the web (GEO).

A practical order for the next month:

1. 1Connect Google Search Console and fix anything stopping your pages being indexed.
2. 2Make sure each service has its own page with a clear title and an answer near the top.
3. 3Check your robots.txt and firewall do not block the AI crawlers you want to be read by.
4. 4Make your name, address, phone and hours identical everywhere.
5. 5Ask ChatGPT, Gemini and Perplexity the questions your customers ask, and write down who they name.

How ParSEO fits

ParSEO does the three together for one business at a time. Every day it checks where you rank on Google, and every week it asks the AI assistants your customers' questions and records whether you are named. Then it fixes what it can on your real site, with your OK, and keeps dated proof of what each change did.

A worked example: one clinic, three kinds of visibility

Take a dental clinic in Indiranagar, Bengaluru (a made-up example). A patient might find it three different ways in the same week:

1. 1SEO: they search "root canal treatment Indiranagar" on Google, see the clinic's treatment page in the results, and click through.
2. 2AEO: they search "how many visits for a root canal" and Google shows a short answer taken from the clinic's page, with its name and link under the answer.
3. 3GEO: they ask ChatGPT "which clinic in Indiranagar is good for a painless root canal" and the clinic is one of the three it names, with a link to its page.

The same page can serve all three if it is built well: a clear title with the treatment and area, a direct answer near the top, honest detail on visits, pain and cost, and the clinic's details matching its Google Business Profile.

Common mistakes when businesses chase AEO and GEO

• Skipping the basics. Writing FAQ pages for AI while the main service pages aren't indexed. Check Search Console first.
• Blocking AI crawlers by accident. Security plugins and CDN bot protection often block them. Check before writing more content.
• Writing for a robot. Pages stuffed with question phrases read badly and convince nobody. Answer real questions the way you would at your front desk.
• Expecting one screenshot to prove anything. AI answers vary from one ask to the next. Track the same questions over weeks.
• Saying different things in different places. One set of facts, everywhere.
