What Does an AEO Agency Actually Do? A SaaS Buyer's Guide

You are about to sign with an AEO agency, and you still cannot answer a simple question: what does an AEO agency do all day, and what do you actually get for the retainer? That gap is normal. Answer engine optimisation is new, the deliverables are less obvious than "we build you backlinks," and most agency pages talk in outcomes without ever showing the work behind them.

This guide fixes that. It breaks down exactly what an AEO agency does, the deliverables you should expect, how long each takes, and what "done" looks like, so you can vet any provider, including us, with real confidence before you spend a dollar.

First, what an AEO agency actually is

An answer engine optimisation agency helps your brand show up inside AI answers. When a buyer asks ChatGPT, Perplexity, Gemini, Claude, or Google's AI Overviews for a recommendation, the agency works to make sure your product is named, described accurately, and cited as a source in that answer.

This matters more every quarter. ChatGPT alone passed 900 million weekly active users, a figure OpenAI confirmed in February 2026 and Reuters reported, and 92% of Fortune 500 companies now use it. Gartner has predicted that traditional search engine volume will drop 25% by 2026 as people move their questions into these answer engines instead of typing them into Google. Your buyers are already among them.

The money follows the behaviour. Seer Interactive found that organic click-through rates fall by around 61% on Google searches where an AI Overview appears, based on September 2025 data. Fewer people click the blue links, and more of them act on the answer they are handed. If your brand is missing from that answer, you are invisible at the exact moment a decision gets made.

The traffic that does come through tends to convert unusually well. Because an AI answer pre-qualifies the buyer before they ever click, referrals from tools like ChatGPT and Perplexity have been reported to convert at far higher rates than standard Google organic clicks in analyses from Seer Interactive and First Page Sage across 2025 and 2026. For a SaaS founder, that is the real prize: not just visibility, but visibility in front of someone who has already been told you are a fit.

Traditional SEO gets you ranked in the list of links. AEO gets you into the answer itself. The two overlap, but they are not the same job, and that difference is the whole reason AEO agencies exist.

What does an AEO agency do, step by step

Here is the real scope of work behind the retainer. A capable AEO agency runs all five of these, not just the one that is easy to sell.

1. Audit your current AI visibility

The first thing an AEO agency does is measure where you stand. That means running your category's actual buyer prompts through ChatGPT, Perplexity, Gemini, and Google AI Overviews, then recording whether you appear, how you are described, and who gets recommended in your place.

You should receive a clear baseline: the prompts tested, your citation rate, the competitors winning those answers, and the specific gaps holding you back. Without this, everything after it is guesswork. Our own AEO service starts here for exactly that reason, because you cannot improve a number you have never measured.

2. Make your site readable and trustworthy to AI

AI systems can only cite what they can parse and trust. So an AEO agency fixes the technical foundation: structured data and schema, clean answer-first page formatting, entity clarity about who you are and what you are known for, and crawlability for the AI bots that feed these models.

This is where a lot of the invisible work sits. It is not glamorous, but it is what lets a model pull a clean, accurate claim from your page and attribute it back to your brand rather than a competitor's.

3. Build content engineered to get cited

This is the largest ongoing deliverable, and it is where good AEO agency services earn their keep. The agency writes content structured the way answer engines reward: a direct answer near the top, specific data, explicit sourcing, and a format a model can lift cleanly into a response.

The evidence here is unusually strong for such a young field. The Princeton GEO study by Aggarwal and colleagues, presented at the KDD 2024 conference, tested 10,000 queries and found that adding statistics, quotations, and cited sources lifted a page's visibility in AI answers by up to 40%. One method, citing your own sources, produced a 115.1% jump in visibility for pages sitting fifth in search results. The takeaway is direct: content can be deliberately built to win citations, and a competent agency knows the patterns that do it.

Expect a defined monthly volume of new posts, each mapped to a specific buyer question, plus continuous optimisation of the pages you already have.

4. Earn off-site authority and citations

AI answers do not only pull from your website. They pull from Reddit threads, review sites, "best tool" roundups, directories, and third-party mentions across the web. An AEO agency builds that off-site footprint: getting you into curated lists, seeding genuine community and Reddit discussion, earning reviews, and placing mentions on domains the models already trust.

This is why AEO agency services usually bundle digital PR and community work with the writing, not instead of it. Models weigh the consensus about your brand across many sources, so the job is to make that story consistent and credible everywhere it appears, not just on your own domain.

5. Measure citations and report on outcomes

Finally, an AEO agency tracks the thing that actually matters: are you being cited more often, by more engines, for more of your buyers' questions over time? Reporting should show citation share, the prompts you now win, referral traffic and conversions coming from AI tools, and what is queued next.

Ask any agency how they define success. If the answer is impressions or keyword rankings alone, they are selling you old-school SEO in an AEO wrapper.

What "done" looks like, and how long it takes

AEO is a compounding programme, not a one-off project, but you should still see a clear arc rather than a vague promise.

In the first 30 days, expect the audit, the core technical fixes, and an approved content plan. By 60 to 90 days, the first content and off-site work is live and indexed, and early citation movement starts to show on lower-competition prompts. After that, momentum builds as more of your content gets picked up and your off-site authority accumulates.

Be wary of anyone promising instant AI visibility. The models re-crawl and refresh on their own schedule, and genuine authority takes a few months to register in their answers.

What an AEO agency does not do

Honest scope matters as much as the deliverables list. A good AEO agency will not promise guaranteed placement in a specific model's answer, because nobody controls that output. It will not try to game models with hidden text or prompt-injection tricks, which get content flagged and can damage your brand. And it will not treat answer engine optimisation as a magic substitute for a real product, sharp positioning, or a website that works.

The uncomfortable truth is that most of the value comes from disciplined content and technical work done consistently over months. Any agency pitching a secret shortcut is a risk, not a bargain.

How to vet an AEO agency before you sign

Run your shortlist through these questions:

• Can they show a baseline audit and ongoing citation tracking, not just rankings?
• Do they name the specific engines and buyer prompts they will target for you?
• Is their content built around specific data and named sources, or is it thin and generic?
• Do they cover off-site authority through Reddit, reviews, directories, and PR, or only on-page writing?
• What does their monthly reporting actually measure?

For the full version, our AEO checklist for founders walks through the exact fixes and vetting questions in order. Take it into every sales call and watch how each agency reacts to it.

Where this leaves you

So, what does an AEO agency do? It measures your AI visibility, makes your site legible and trustworthy to answer engines, builds content designed to get cited, earns the off-site authority models rely on, and reports on citation growth month over month. Done well, it places your product inside the answer your buyer reads before they ever reach a page of search results.

That is the work we do at avinashvagh.com, built specifically for SaaS and AI founders, focused on Australian startups and working with a global client roster. If you want to see exactly where you stand today and what a realistic 90-day plan looks like, book an AEO scoping call and we will run your real buyer prompts live and show you the gaps. It is the fastest way to turn "I think we should do AEO" into a plan you can actually judge.
