GEO vs AEO vs SEO: What Contractors Should Know

SEO earns rankings in search results, AEO earns the quoted answer, and GEO earns a mention inside an AI generated reply. They differ in where you show up, not in what you need to build.

Search engine optimization is the classic work. You make pages that Google can crawl, that match what people search, and that other sites trust. Success looks like a top position for a search such as "water heater repair Chula Vista" or a spot in the Map Pack.

Answer engine optimization grew out of featured snippets and voice search. The goal is a short, direct answer that a search feature or assistant can read out or show as is. Success looks like your sentence appearing in a snippet or a People Also Ask box.

Generative engine optimization is the newest label. It targets tools that write a full answer and cite a few sources, like ChatGPT search, Gemini, Perplexity, Copilot and Google AI Overviews. Success looks like the AI naming your company, or linking to your page, when a homeowner asks who to hire.

GEO comes from a 2023 research paper titled "GEO: Generative Engine Optimization" by researchers at Princeton University and IIT Delhi. It was later published at the KDD 2024 conference.

The authors built a benchmark called GEO bench with 10,000 queries. They then tested ways of rewriting web content to see which changes made a source more visible in AI generated answers. In the abstract, they report that GEO methods can "boost visibility by up to 40%" in those answers.

The methods that did best were adding relevant quotations, adding statistics and citing sources. Improving fluency also helped. Keyword stuffing, the old trick of repeating a phrase, did worse than leaving the content alone.

Keep the limits in mind. This was a lab test on a research benchmark, not a study of local contractors or live Map Pack results. It still gives a useful signal: AI tools favor content that is specific, sourced and easy to quote.

The table below shows the goal, the main surface and the signals that matter for each. Notice how much of the right column repeats.

The big takeaway is overlap. A contractor who does SEO well, writes clear answers and keeps listings clean is already doing most of GEO.

All three reward the same thing: a real business that is easy to verify and easy to understand. Google states that "there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary."

Google also says a page must be indexed and eligible to show with a snippet to appear as a supporting link in its AI features. That means technical SEO still decides whether you are in the game at all.

The shared foundation for a contractor looks like this:

GEO puts more weight on what others say about you and on content that an AI can quote in one piece. Links still matter, but mentions and clarity matter more than many owners expect.

In a 2025 Ahrefs study of 75,000 brands, branded web mentions showed a 0.664 correlation with brand visibility in Google AI Overviews, compared with 0.218 for backlinks. Ahrefs notes that correlation is not causation, and the study covered larger brands, not local trades. The pattern still points to reputation across the web.

AI tools also pull from places your website does not control. Ahrefs data updated in September 2026 showed Reddit with 16.8% of the top cited sources in ChatGPT across US queries. For local searches, BrightLocal ran 800 ChatGPT searches in November 2024 and found business websites made up 58% of sources, business mentions 27% and directories 15%.

So GEO adds a few habits on top of SEO:

Fix the basics in this order: your Google Business Profile, your core service pages, then your listings and reviews. These help SEO, AEO and GEO at once, so no effort is wasted.

Week one, confirm your profile is verified, your primary category is right and your service area matches where you really work. Week two, rewrite your top three service pages so the first paragraph answers "what do you do, where, and how do I book" in plain words. Week three, audit your listings for mismatched names or old phone numbers. After that, build a steady review habit and add a short FAQ to each service page.

Only then look at extras like content hubs, comparison pages or outreach for mentions. A painter in Eastlake or a roofer in National City will get more from clean basics than from any GEO tactic layered on a weak site.

At WebSEO.pro we work with contractors across Chula Vista and San Diego County, and we start every engagement with this same order. A free visibility audit is a simple way to see which of these basics your business already has and which ones are missing.

Skip anything that promises a shortcut into AI answers. Google says its AI features need no special schema or machine readable AI files, and no tool can guarantee placement.

Be wary of these:
