AEO agency vs SEO agency: what is different and which you need

Two proposals, two finish lines: a ranked page or a name inside the answer.

Back in 2018, Perry Rosenbloom of Brighter Vision gave a therapists' podcast a definition of SEO that still holds: making sure search engines understand what a business is about, which clients it works with, and which areas it serves. Not tricking Google. Just being understood.

That definition is quiet, and it is old, and I keep coming back to it. An SEO agency takes that job and aims it at the ranked list of blue links. An AEO agency aims the same understanding at a different place: the paragraph ChatGPT, Perplexity, Google AI Overviews and Gemini write back when your buyer asks a question out loud.

The difference sounds small. It is not.

A ranked page can still sit outside the answer, and a buyer who reads only the answer never scrolls down to find you. So the useful question for a business owner is not which label is newer. It is which surface your next customer actually reads before they pick up the phone, and who on your payroll is accountable for your name showing up there.

What is the difference between an AEO agency and an SEO agency?

The short answer: an SEO agency works to rank your pages in the blue links, while an AEO agency works to get you named inside the answer.

Before you sign with either one, sit with four plain questions:

1. Where do your buyers start: a Google results page, or a question typed into ChatGPT, Perplexity, Gemini or Google AI Overviews?
2. Does the agency report rankings and clicks, or whether your business is named for each buyer question?
3. Who fixes the shared basics, so you pay for them only once?
4. Which business outcome is the monthly fee actually tied to?

Answer engine optimization (AEO) is the work of making a business the source an AI engine names when it answers a question. Search engine optimization is the older craft of earning a high spot in a list of links. The two are cousins. They are not twins.

RealSiteWorth put it bluntly in August 2026, reporting that Google's own generative AI optimization guide says AEO and GEO are still SEO. Google's AI features pull from the same Search index, and one question quietly fans out into several related searches behind the scenes. So the foundation is shared. Ask any agency which part of its fee pays for that shared foundation. A study cited in the same RealSiteWorth article found that a citation and a top-ten ranking overlapped often, but far from always: only 37.9% of cited URLs sat in the top ten.

The common assumption is that a strong Google position carries straight into the AI answer. Often it does not. Your own best-ranking page is the easiest place to test it. Another page can be quoted without ranking first, because the engine stitches several sources into one reply and picks the passages it can lift cleanly.

I built this company with a co-founder who is a full-stack engineer and content infrastructure architect with 20 years of building enterprise systems, and our scoring now covers 11,000+ domains across 15 sectors and 28 categories. I keep coming back to one plain point from all of it. The point is practical: ask an agency to show you, for one buyer question, which pages the AI answer cites today and what it will do about each one.

That gap gives you a quick test for any agency, whatever it calls itself.

In a July 2026 thread on Reddit's r/smallbusinessUS, the founder of a new AI SEO agency described posting on LinkedIn, sending personalized messages and offering free AI visibility audits, and still getting "very few replies or meetings." One commenter explained why buyers hesitate: "The first thing I'm looking up for a company in the SEO space is if they actually do it well for themselves or have real examples of them achieving results for their clients." I think that is the right instinct. Ask an SEO agency where it ranks for its own service terms. Ask an AEO agency something different. Open ChatGPT, Perplexity or Gemini, type the question you would type when hiring, and see who gets named. An agency that cannot get itself into that answer is asking you to trust a skill it has not shown. Another commenter, with 15 years in the field, said they had never felt a change this big.

If the vocabulary still feels foreign, our AEO knowledge base defines each term in plain words. Then comes the harder question, the one owners ask me with their arms crossed, half expecting a sales pitch: is any of this actually new?

Is AEO just SEO with a new name?

Partly, yes: the plumbing overlaps, but the promise differs, because an AEO agency answers for whether you are named in AI answers, and ours keeps working free until you are.

I understand the suspicion. Alex and I bring a combined 40+ years of SEO and content infrastructure experience to this work, so I won't pretend the craft was invented last spring. Clean pages still matter. Structure still matters. What changed is where the customer hears the answer.

The friction shows up in what some SEO retainers actually deliver. In a December 2025 thread on Reddit's r/SEO, a marketer described hiring an SEO agency for "some schema fixes and 30 content optimizations a month." The rewrites stripped references to the company's own product, turned one piece "very generic," and recommended a competitor. Another article came back carrying references to diabetes and the pancreas in a post about a feedback process, which the poster suspected had bled over from another client's prompts.

One commenter in that thread put the problem in a single line: "They are selling you a deliverable (30 articles/month) to justify a retainer, not actual SEO strategy." Another warned that "site quality is judged at the domain level," so careless rewrites can drag down pages that were already working.

Read that story twice. It is the whole tension in miniature.

A count of deliverables looks like progress on an invoice. For AI answers, the damage runs deeper than a lost ranking. An engine trying to decide who solves a problem cannot name you once your own pages have stopped saying what you sell, the way a familiar song sounds wrong when a stranger hums it with the chorus missing. Your product context is the chorus.

So the yardstick has to move from output to outcome. One of our clients, Modern Wealth, went from a quiet site to 10 booked calls in 3 weeks. That is the kind of number a retainer should answer to. An article count is not.

None of this means every SEO agency is careless, or that every AEO label is honest. A broader definition of search helps here.

Brandon Leibowitz, an SEO firm owner who has worked in digital marketing since 2007, said on his podcast in June 2025 that people "just think SEO is Google. But it's really anywhere where you could search, essentially." He counted YouTube for videos, Amazon for products and Yelp for businesses. By that reading, an AI assistant was one more place people search, and the old craft stretches to cover it. I find that fair, up to a point. Every one of those platforms still hands back a list you can climb. An answer from ChatGPT or Perplexity usually hands back a few names and stops. There is no page two to fight for. Leibowitz also told listeners he would not fully trust what Google tells you, because Google wants you spending money on ads. Keep that skepticism close when anyone, us included, says the old work already covers the new job.

A September 2026 YouTube playbook from a vendor selling tools to AEO agencies treated "AI SEO or LLMO or GEO AEO" as names for one service, so ask what a proposal delivers before you weigh what it is called. If you want to see what evidence-led work looks like up close, our notes on research-driven content show how each claim in an article gets tied to a source before it ships. The harder sorting starts with the work both kinds of agency share, because that is where owners most often pay twice.

What does an AEO agency do that an SEO agency does not?

An AEO agency researches the questions buyers ask AI, writes answer-first passages, keeps your business identity consistent everywhere, and tracks whether you are named, question by question.

Before AEO Content, I founded LiveHelpNow, which made the Inc. 5000 at number 84. A support business lives on one thing: did the customer get a straight answer to the question they actually asked? AI engines run on the same principle. They reward the source that answers cleanly.

That is where the work splits off from classic SEO. Five jobs belong to the AEO side:

• Question research. Mapping the exact questions buyers type into ChatGPT, Perplexity and Gemini, not just the short keywords they type into Google.
• Answer-first content. Putting the direct answer in the opening one or two sentences of each section, so an engine can lift the passage whole.
• Entity consistency. Making sure your name, services and location read the same on your site and on every source the engines crawl.
• Named or not named, per question. Checking each target question and recording whether your business appears in the answer.
• AI referral visits. Separating the visits that arrive from AI engines so you can see what the mentions are worth.

When we mapped 17 AEO checks against a standard SEO audit, the practitioner view we kept running into was blunt. If structured data, content architecture changes and AI visibility monitoring are not in the deliverables, one commenter wrote, "it's a rebrand not a new service." I agree with that line more than I'd like to admit.

The tracking piece is where most reports go soft. A practitioner building a product in this space wrote in an August 2026 r/aeo thread that a brand can look fine in early informational answers and then vanish once the question moves toward a decision. Most reporting averages the two into one number. The drop never shows. As the same poster put it: "The tools report what happened. The judgment and the deliverable stay manual."

A second thread on r/aeo that month made the matching point about software. Tools now surface opportunities by the dozen, and one commenter observed that "the hard part isn't finding opportunities anymore, it's choosing what to ignore."

So the agency is paid for judgment. Not dashboards. Choosing which five questions matter to your revenue, and fixing the pages until the answer says your name, is the job. If you want the definitions behind each of those five jobs, our AEO FAQ walks through them one at a time. The obvious next question is what that work costs you on top of the basics you may already be paying someone else to handle.

What should you decide before your next agency renewal?

Decide which AI answers you must be named in, then hire for that job. Write that list before reading any proposal. It shows whether you need one agency, the other, or both.

The evidence points one way. Gartner, in a December 2025 webinar on search marketing, framed the two as partners rather than rivals: "Combining SEO and AEO strategies improves an organization's visibility while positioning content as a trusted source for AI results." For most owners, that turns the renewal into a question of who handles each half, and whether one contract can hold both. I think the next two years belong to agencies that report on the answer itself, question by question, engine by engine.

Rosenbloom said something in that 2018 interview that I still find myself repeating. He described SEO as a garden: you plant the seeds, then you water, prune and protect them over time. AEO tends the same garden. What changed is who walks past it.

So pull up the questions your best customers asked before they called you. Ask your current agency which of those answers names you today. If nobody can say, ask for that answer in writing before you sign the renewal.

If you want one contract that covers both halves, our AEO agency plans are Growth $99, Premium $250, Business $500 and Business Plus $1,000 a month, no contract, cancel anytime. The promise is in writing: you are named in AI answers across the agreed target questions within 100 days, or we keep working free until you are.
