GEO vs SEO: What Changes for a Small Business

GEO (generative engine optimization) and AEO (answer engine optimization) are new names for the work of being found in AI-written answers. Much of it is the SEO you already know. A few things really do change. Here is how to tell which is which, without the hype.

Definitions

• SEO aims to rank pages in a list of search results so people click through.
• GEO / AEO aim to have your business named, summarized, or cited inside an answer an AI engine writes.

The terms are informal. Researchers used "generative engine optimization" in a 2023 paper (Aggarwal et al., "GEO: Generative Engine Optimization"), and agencies have since adopted the label. There is no standard definition and no certification worth paying for.

What stays the same

Google says its AI features rely on the same foundations as Search: a page must be indexed and eligible to show a snippet, and normal SEO best practices apply (Google: AI features and your website). Other engines that search the web depend on crawling and indexing too. So the basics carry over:

• A fast site that works on phones.
• Pages that can be crawled and indexed.
• Clear titles, headings, and text.
• A complete Google Business Profile for local businesses.
• Accurate, consistent business details across the web.
• Real reviews and real mentions from other sites.
• Useful content that answers actual customer questions.

What really changes

1. The unit of success is a mention, not a click

In classic SEO you count rankings and visits. In an AI answer, a customer may read your name in the summary and never visit a results page. Being named matters even if no click follows. Being cited as a source adds a link that may bring a visit. Measure both separately.

2. Fewer slots

A results page has ten blue links. An AI answer may name three to five businesses. The gap between being named and being absent is sharper.

3. Answers vary run to run

Search rankings move, but a given query gives the same page to most users at a given time. AI answers are generated, so asking twice can give different lists. You need repeated sampling to know whether you appear reliably, sometimes, or never.

4. More engines, more crawlers

You now have to think about OAI-SearchBot, PerplexityBot, Claude-SearchBot, Googlebot, and others, and decide separately about training crawlers. See the robots.txt guide.

5. Third-party sources carry more weight than you may expect

Answers to "who is the best X in Y" often cite directories, review platforms, and community discussions rather than the business sites themselves. Check which sources are cited for your category in your city, and be accurately present on them.

6. Passage-level clarity

Systems that retrieve and quote text pull passages. A paragraph that makes sense on its own, with a specific fact, is more usable than one that depends on surrounding context.

What is hype

• Claims of secret formulas for ranking in ChatGPT.
• Promises of placement. No one controls what a model writes.
• Prompt tricks hidden in your pages. Search engines and AI providers treat hidden text and manipulation as abuse, and it can backfire.
• Single-number "AI scores" without a published method. Ask any vendor, including us, to show the prompts and the raw answers. Ours are on the methodology page.

A sensible plan for a small business

1. Measure first. Ask the five or six questions your customers ask in several engines. Record who is named and what is cited. The checking guide shows how.
2. Fix access. Make sure the crawlers you want can reach your site.
3. Fix facts. Put clear, complete business facts on your site and keep them identical elsewhere.
4. Fix listings. Complete your Google Business Profile and the third-party sites that appear in answers for your field.
5. Add structured data that matches the page (guide).
6. Publish useful answers to the questions customers really ask.
7. Re-measure on a schedule. Changes take weeks to show up, and answers vary, so compare like with like.

How much to spend

For most small businesses, the first steps cost time, not money. Be skeptical of retainers that promise AI placement. A measurement tool is useful because it tells you whether the work is moving anything, but it is not the work itself. If you want help with the work, our studio, MR Enterprises, offers website, schema, and Google Business Profile services, and the link is labeled as such wherever it appears.

See where you stand

SearchSignal's free check asks ChatGPT, Google AI Overviews, Perplexity, Gemini, and Claude the kind of questions your customers ask, and shows what each said. The paid report adds repeat runs, an on-site audit, and a prioritized fix list.

Common questions

Is SEO dead?

No. The AI engines that search the web rely on crawling, indexing, and sources. The skills overlap heavily.

Do I need a GEO agency?

Probably not at the start. Most first steps are checks and fixes you can do yourself, or have your web person do. If you hire help, ask for a written scope and no promises of placement.

Which engine should I care about most?

The one your customers use. We do not have a defensible usage-share number, which is why SearchSignal weights all five engines equally and shows each separately.

How do I know it is working?

Measure with the same questions on a schedule, and look at both mentions and citations. One good result is not a trend.
