SEO vs AEO vs GEO: what a home-service business actually needs

If you run a roofing, HVAC, plumbing, landscaping or remodeling company, you need all three eventually, but not at the same time. Start with SEO, because Google Search and Google Maps still send most of the calls. Add AEO once your service pages exist, so your answers are the ones Google pulls into snippets and People Also Ask. Layer GEO on top so ChatGPT, Gemini and Perplexity can describe your business accurately when a homeowner asks them for a recommendation. The order matters more than the acronyms.

What do SEO, AEO and GEO actually mean?

SEO: being found in search results

Search engine optimization is the work that gets your pages to appear in Google and Bing results for the things people type: "roof repair near me," "furnace replacement cost," "deck builder in [town]." It covers three areas: a technically sound website that Google can crawl and that loads fast on a phone, pages that match what buyers are searching for, and signals of trust such as reviews, citations and links from relevant sites. Local SEO is the part of SEO that targets the map pack and your Google Business Profile.

AEO: being chosen as the answer

Answer engine optimization is about the moments when a search engine answers the question directly instead of listing ten links. Featured snippets, People Also Ask boxes, voice assistants and Google's AI Overviews all pull short passages from pages that answer a specific question clearly. AEO means writing those passages on purpose: a plain question as a heading, a direct answer in the first two or three sentences, then the detail. It also means marking up FAQs and how-to content so the engine can read the structure.

GEO: being understood and recommended by AI assistants

Generative engine optimization is the newest of the three. Large language model assistants such as ChatGPT, Gemini, Claude and Perplexity do not just rank pages; they synthesize an answer and sometimes name businesses. To be named, your company has to be clearly described across the web: consistent name, services, service area and specialties on your site, your Google Business Profile, directories and review platforms. GEO is largely entity work (making it unambiguous who you are and what you do) plus publishing content that an assistant would be comfortable citing.

How do the three compare?

The rows that matter most for a contractor are the first and the last. The surfaces are different, so the tactics overlap but are not identical. And none of them can be guaranteed, because Google and the AI companies decide what to show.

Why does the order matter?

AEO and GEO both depend on content that already exists. A snippet cannot quote a page you have not written. An AI assistant cannot describe a service you have not listed. That is why the practical sequence for most home-service businesses is:

1. Fix the foundation. A fast site, clean indexing, one page per service, one page per city you want to win, and a complete Google Business Profile.
2. Write answers into those pages. Every service page should answer the questions a homeowner asks before calling: what it costs, how long it takes, whether they need a permit, what can go wrong.
3. Make the entity unambiguous. The same business name, address, phone and service list everywhere. Organization and LocalBusiness schema on the site. Descriptions that say what you do in plain words.

Steps two and three are the AEO and GEO work. They are far cheaper when step one is done.

Where should you start, based on your stage?

You have a website but it does not rank for your own services

Start with SEO, specifically local SEO. Audit the technical basics, build or rewrite service pages for your top three services, and finish the Google Business Profile. Do not spend on AI visibility yet; there is nothing for the assistants to find.

You rank for some terms and get steady leads

Add AEO. Look at Search Console for queries phrased as questions ("how much does," "do I need," "how long"). Add question-led sections to the pages that already rank for them. Add FAQ schema where the FAQs are genuinely on the page. This is usually the fastest win available to a business at this stage.

You are an established name in your market

Add GEO. Test a set of prompts in ChatGPT, Gemini and Perplexity ("best roofing company in [city]," "who should I call for a leaking roof in [county]") and record what they say about you and your competitors. Fix the gaps: missing services, outdated descriptions, inconsistent names across directories, a thin About page. Publish the kind of content assistants cite: clear explanations, comparisons and process pages.

You are a new business with no website yet

Build the site with all three in mind from the start. It costs nothing extra to structure a page with a question heading and a direct answer, or to add schema on day one. The budget still goes to SEO first.

What can each one not do?

• SEO cannot make a slow, confusing site convert. Rankings bring visitors; the page has to do the selling.
• AEO cannot force Google to show a snippet. You can make your page the best candidate; Google decides whether a snippet appears at all.
• GEO cannot make an assistant name you. AI answers vary by phrasing, by day and by user. You can make your business easy to describe accurately; you cannot buy a mention.
• None of them replace reviews and response time. A homeowner who finds you through any surface still checks your reviews and calls the first business that picks up.

How do you know if it is working?

Pick one or two metrics per surface and watch them monthly:

• SEO: organic clicks and map pack positions for your service-plus-city terms, and the number of calls and form fills attributed to organic search.
• AEO: which question queries you own a snippet or People Also Ask result for, and impressions on those queries.
• GEO: a fixed set of prompts run on a schedule, logged with what each assistant says, plus any referral traffic from AI tools in GA4.

If an agency reports only rankings, ask for the lead numbers. If it presents AI mentions as a guarantee, be skeptical; nobody controls those outputs.

The short version

SEO gets you found. AEO gets you quoted. GEO gets you described correctly and, sometimes, recommended. A home-service business should build them in that order, on the same website, with the same honest content. The companies that do well across all three are not using a trick; they are the ones whose online presence is complete, consistent and useful.
