AEO vs GEO vs SEO: What Actually Changed for Local Businesses

Three acronyms are being sold to local business owners right now, often by the same agency, sometimes on the same call. Here is what they actually mean and what changed.

The one-line version

• SEO — Search Engine Optimization. Get onto the results page.
• AEO — Answer Engine Optimization. Get named inside the answer.
• GEO — Generative Engine Optimization. Same as AEO, different origin story.

GEO came out of a 2023 academic paper studying how to influence generative search results. AEO came out of the SEO industry, originally describing optimization for featured snippets and voice assistants, then expanding to cover AI answers. The two converged. Anyone drawing a hard line between them is drawing it for marketing reasons.

Use whichever word your agency uses. The work is the same.

What actually changed

There is no list anymore

This is the change that matters, and it is bigger than it sounds.

A Google results page for "roofers in Sacramento" shows ten organic results, a three-pack map, and ads. Position four still gets clicks. Position eight still gets clicks. The homeowner is doing the comparison themselves, and being present is most of the battle.

Ask ChatGPT the same question and you get three names, maybe four. There is no position five. The assistant has already done the comparison and made the shortlist. Being present is the entire battle, and most businesses are not present.

The unit of optimization moved from page to entity

Classic SEO optimizes a page for a query. You had a page targeting "water heater repair Sacramento," and it competed against other pages targeting the same string.

AI systems reason about entities — a business as a thing with properties: name, location, services, hours, reputation, phone number. Your website is one source of facts about that entity, not the entity itself. Your Google Business Profile is another. Yelp is another. A Reddit thread is another.

The practical consequence: you can have a technically perfect website and still be invisible, because five directories list you under three different phone numbers and the model has no confident picture of who you are.

Off-site signals got heavier

SEO always cared about backlinks, but a link was mostly a vote of authority. In AI answers, a mention is a fact-check.

When an assistant is deciding whether to recommend "Carter Plumbing," a mention in a local news article, a chamber of commerce listing, a supplier's certified-installer directory, and a Reddit thread all serve the same function: independent confirmation that the business is real, operating, and has a reputation. This is why businesses with mediocre websites sometimes dominate AI answers, and why contractors with beautiful sites and zero off-site presence get nothing.

Structured data went from nice-to-have to load-bearing

Schema markup was always a modest SEO nicety — it got you a star rating in the search results, sometimes.

For AI systems it is the difference between stating a fact and hoping one is inferred. LocalBusiness schema tells a machine your service area, hours, and phone number in a format that requires no reading comprehension. FAQPage schema hands it question-answer pairs pre-formatted for exactly the job it is doing.

Content structure started mattering more than content length

The 2,500-word blog post built to rank has no special advantage in an AI answer. What gets lifted is an extractable unit: a direct forty-word answer, a definition, a numbered list, a comparison table.

The best-performing structure now is answer-first — question as a heading, direct answer immediately underneath in plain language, elaboration after. That is the opposite of the "build up to it" essay structure that SEO content drifted into.

What carried over unchanged

Plenty. Anyone telling you to throw out your SEO is selling a rebuild you do not need.

Still matters, unchanged:

• A fast site that renders its content in HTML
• Accurate, complete Google Business Profile
• Real reviews, recently, with responses
• Pages that actually cover what you do and where
• Correct name, address, and phone everywhere
• Clean internal linking and a sitemap

Stopped mattering, or never mattered:

• Keyword density and exact-match repetition
• Thin city pages that swap one word
• Bought links and directory spam
• Meta keywords (still dead, still being sold)
• Word count for its own sake

Where the three overlap, in one table

Work	Helps SEO	Helps AEO/GEO
Google Business Profile completeness	Yes	Yes — heavily
LocalBusiness JSON-LD schema	Slightly	Yes — heavily
FAQ content with FAQPage schema	Yes	Yes — heavily
Consistent NAP across directories	Yes	Yes — heavily
Reviews volume and recency	Yes	Yes
Third-party mentions (news, forums, directories)	Some	Yes — heavily
Site speed and HTML rendering	Yes	Yes
Long-form blog content	Yes	Only if answer-first
Keyword-targeted thin location pages	Declining	No
Paid link building	Risky	No

The pattern: almost everything that helps AEO also helps SEO. The reverse is not true. That is the correct way to think about budget — AEO work is mostly a re-prioritization of local SEO work, not a second budget line.

What this means for your money

If an agency proposes "GEO services" as a new $2,000/month line item on top of your existing SEO retainer, ask them to show you what the SEO retainer has been buying. In most local service accounts we look at, the retainer has been producing thin blog posts and directory submissions, and the highest-value AEO work — schema, Google Business Profile depth, real question-answering content, review velocity, third-party mentions — was never being done at all.

That is a re-prioritization conversation, not an upsell conversation.

What to do this week

1. Ask ChatGPT, Perplexity, and Google (with AI Overviews on) the top three questions your customers ask. Write down every business named.
2. Count how many of those competitors have a complete Google Business Profile versus how many have a better website than you. The answer usually surprises people.
3. Pull your current SEO invoice and map each line item to the table above.
4. Add LocalBusiness schema to your homepage — it is the single cheapest item on the list.

The measurement problem

Rank tracking does not work here. There is no rank. The only measurement that means anything is: when a customer asks, does the assistant say my name?

Our free scan runs twenty-five real customer questions across ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews, then shows you every verbatim answer and every competitor named in your place. It takes about fifteen seconds and does not require an account.

Run it before you renew any retainer.
