AEO Agency: What They Actually Do, What to Avoid, and the Honest Verdict

Quick answer: An AEO agency (answer engine optimization agency) gets your brand cited in the answers that AI engines like ChatGPT, Perplexity, and Google AI Mode write for users, instead of just ranking on a page of blue links. AEO is real, and it is converting far better than classic SEO right now. HubSpot's CMO told Alex Lieberman that AI search converts about 5x higher than Google search, and Lenny Rachitsky calls it "the largest new marketing channel in over a decade." But the agency market is young and uneven. Plenty of "AEO agencies" hand you a checklist, a deck, and an invoice. The biggest levers are not secret: community presence (especially Reddit), structured answer-first content, and entity authority, all refreshed continuously because AI citations change month to month. The real question to ask any agency is simple. Do they install the system that does this work, or do they sell you a one-time audit and walk?

That distinction is the whole article. Here is the rest of it.

What is an AEO agency?

An AEO agency optimizes your brand to be the source AI engines cite when they answer a question. Traditional SEO chased rankings on a results page. AEO chases the answer itself, the paragraph ChatGPT writes, the summary Perplexity returns, the box Google AI Mode shows above the links. AEO is a specific subset of what gets sold as "AI SEO", and the distinction matters when you're evaluating agencies.

This matters because answers are eating clicks. Ahrefs found that when an AI Overview appears, the top-ranking page sees a 34.5% lower average click-through rate. You can hold your number-one ranking and still lose the traffic, because the user got their answer without scrolling. So the work shifts. Instead of "rank this page," the job becomes "be the brand the engine names when it writes the answer."

The volume behind this is not small. Frase reports ChatGPT handles 2 billion or more queries per day, and AI-referred sessions grew 527% year over year through mid-2025. That is a channel forming in real time.

A good AEO agency does some mix of these things: structures your content so engines can extract clean answers, builds your presence on the sources AI actually pulls from, strengthens the entity signals that tell engines who you are and what you are credible on, and monitors which engines cite you for which questions over time. The honest version of the job is research plus production plus continuous maintenance. The dishonest version is a slide deck.

Is an AEO agency worth it? (what the data and the skeptics say)

I am going to give you both sides, because the truth is in the tension between them.

The bull case is strong and it is coming from serious operators. Lenny Rachitsky says AEO is "the biggest change in search and the largest new marketing channel in over a decade," and notes companies optimizing for AI answers are seeing roughly 6x higher conversion rates than Google traffic, with early-stage startups able to win quickly before incumbents wake up. Greg Isenberg, citing Cody Schneider's playbook, puts it even harder: "AI search converts at 10-40% vs 1-2% from SEO." His tactic is to track which URLs LLMs scrape, get mentioned on those pages (sometimes for as little as around $500 or an affiliate rev share), and show up in AI answers within about 24 hours, versus 6 to 12 months for traditional SEO. He calls it "pure arbitrage" and openly says it may not last.

Then there is Alex Lieberman, who was skeptical AEO was even real until HubSpot's CMO Kipp Bodnar told him HubSpot grew AI search traffic 15x in a year, that AI search conversion rates run about 5x higher than Google search (13x on some queries), and that 60% of AI citations do not come from the top 20 Google results. That last stat is the important one. It means AEO is not just SEO with a new name. The winners are often not the pages that already rank.

Now the skeptic case, because it is just as real. Go read the buyer-side threads. r/AskMarketing has a thread titled "Are AEO agency services worth the cost or are most just giving you a checklist to implement yourself?" r/content_marketing is asking "Are answer engine optimization services worth it?" And r/growmybusiness has "Has anyone here hired an AEO agency with real results?" The pattern across all three is the same suspicion: that you are paying retainer money for a deliverable you could implement yourself, with no proof the engine ever cites you.

Both things are true at once. The channel is real and the upside is large, and a chunk of the agency market is selling thin work at thick prices. So the verdict is not "AEO agency yes" or "AEO agency no." It is "AEO is worth doing, and the question is whether your provider actually does it or just describes it." The data says go. The Reddit threads say check who you go with.

What AEO actually requires

Here is the work itself, so you can judge whether anyone is actually doing it.

Community and Reddit presence. This is the lever most people underrate. Semrush analyzed 230,000+ prompts and 100 million+ AI citations and found Reddit and LinkedIn among the top five most-cited domains across ChatGPT, Google AI Mode, and Perplexity. Profound's analysis of over 1 billion citations found Reddit the single most-cited site by Perplexity, and the second-most by both Google AI Overviews and ChatGPT. If your brand has no genuine presence in the communities engines pull from, you are invisible in a huge share of answers. This is also why Isenberg's "get mentioned on the pages LLMs scrape" tactic works.

Structured, answer-first content. Engines extract. They reward content that states the answer clearly and early, defines entities plainly, and is organized so a machine can lift a clean paragraph without guessing. The "Quick answer" block at the top of this post is not decoration. It is built to be extracted. Burying your answer under 600 words of throat-clearing is an AEO mistake.

Entity authority. Engines need to know who you are, what you are credible on, and how you connect to the topics you want to win. That is consistent naming, claims an engine can corroborate across multiple independent sources, and the kind of cross-source presence that makes a model confident enough to name you. You do not earn this with one page. You earn it across the web.

Continuous refresh, because this moves. This is the part that kills one-time projects. eMarketer reports that between 40% and 60% of cited sources change month to month across Google AI Mode and ChatGPT. Win a citation in April and you can lose it by June without touching anything, simply because the engine reshuffled. AEO is not a project with an end date. It is a system that has to keep running, which is exactly why "checklist and invoice" fails and why an installed, always-on motion wins.
