GEO vs SEO: what generative engine optimization means for a local business

If you own a business in Bucks County, you've probably had an email in the last year offering "GEO," "AEO" or "AI SEO." The letters are new. Much of the work isn't. Here's what each term means, where they overlap and what a local business should actually do first.

Three terms, plainly

SEO: search engine optimization

SEO is the work of helping your pages show up in search results. For a local business that has two halves: the regular list of web results, and the map pack with three businesses under a map. It covers your website, your Google Business Profile, your reviews and the listings that confirm who and where you are.

AEO: answer engine optimization

AEO started with featured snippets and voice assistants. Ask a smart speaker "How long does a water heater last?" and it reads one answer from one page. AEO means writing pages so a search engine can lift a clear, direct answer from them: a question as a heading, a two-sentence answer underneath, the detail after.

GEO: generative engine optimization

GEO is about AI-written answers. ChatGPT, Gemini, Perplexity and Google's AI Overviews and AI Mode don't just quote one page; they read several and write a new answer, often naming two or three businesses. GEO aims to make your business one of the names, and your pages among the sources.

The term comes from a research paper, "GEO: Generative Engine Optimization" (Aggarwal et al., first posted to arXiv in November 2023 and presented at the KDD 2024 conference). The researchers tested rewrites of web pages against AI answer engines. Adding quotations, statistics and cited sources raised a page's visibility in AI answers by up to about 40% in their tests. Stuffing pages with keywords did worse than doing nothing. Those were lab tests on general web content, not local map results, but the lesson carries over: specific, well-sourced facts get used; filler doesn't.

What Google says

Google published guidance on optimizing for its generative AI features in 2026. As of October 2026, it says:

• The usual SEO best practices still apply to AI Overviews and AI Mode.
• There are no extra technical requirements beyond being indexed and eligible for a normal search snippet.
• You don't need special AI text files or special schema markup to appear, though structured data is still worth having as part of good SEO.
• Focus on helpful, original ("non-commodity") content rather than AEO or GEO tricks.

That's Google, which runs only some of the assistants your customers use. But it matches what we see with the others too.

What overlaps

For a plumber in Feasterville or a dentist in Doylestown, the overlap is most of the job.

• An accurate, complete Google Business Profile. Google's AI answers lean on it heavily.
• Consistent listings everywhere. Assistants check Bing, Apple, Yelp and directories, not just Google. Our guide to local citations covers which matter first.
• Clear pages for each service and town. These feed regular results, snippets and AI answers alike.
• Real reviews, replied to. Ratings help the map pack, and AI assistants often summarize what reviewers say.
• A fast, crawlable website. If a crawler can't read it, no engine can use it.

A hypothetical example. An HVAC company in Northeast Philadelphia adds a page for heat pump installation that lists the neighborhoods it covers, a typical price range, how long an install takes and which rebates it helps with. That one page can lift it in regular results, give Google a clean answer for a snippet, and hand ChatGPT the specific facts it needs to describe the company. One piece of work, three kinds of visibility.

What's actually new for a local business

A few things do change when the answer is written by AI.

1. Google isn't the only gatekeeper. ChatGPT and Copilot lean on other search indexes and data sources, so a wrong Bing or Apple listing now costs more than it used to.
2. Questions get longer. People ask "Who can replace a roof in Newtown before winter and handles the insurance claim?" Pages that answer specific questions get used.
3. Specific facts get quoted. Price ranges, timelines, warranties, the towns you cover, license numbers. Vague claims like "quality service" give an assistant nothing to repeat.
4. Mentions beyond your own site count. A local news roundup, a chamber listing or a neighborhood forum thread can be the source an assistant trusts.
5. Measurement is rougher. There's no AI rank tracker you can fully trust. Repeating a fixed prompt list each month is the best method we've found; our post on checking whether ChatGPT recommends your business has the list.

What to do first

In this order, for most local businesses:

1. Fix your Google Business Profile. Categories, services, hours, service areas, photos.
2. Clean up your main listings. Bing Places, Apple, Yelp, Facebook, the BBB and your industry's directories.
3. Write or rewrite service and town pages with the specific facts customers ask about.
4. Add an FAQ section to key pages, with real questions and direct answers.
5. Add structured data that matches what's on the page: your business type, service area and FAQs.
6. Check your robots.txt so AI search crawlers can read your site.
7. Run a monthly prompt test and keep the results.

An llms.txt file is a reasonable small extra after those, not before.

Our AI search optimization work covers these steps and comes with our local SEO plans. If you sell beyond the map, say an online store or a firm with clients across the country, our national and AI search SEO service handles the content and tracking at that scale.

GEO tactics to skip

• Pages written by AI in bulk for every town and service combination.
• Hidden text or "instructions" meant to steer AI assistants.
• Fake or paid reviews.
• Anyone promising that ChatGPT will name you first. Nobody controls these answers.
