AEO Agency: What It Does, What It Costs, How to Vet One

What an AEO agency is

Answer engine optimization, or AEO, is the work of making your pages the ones an answer engine quotes or links when it answers a question directly. An answer engine is any search or AI tool that writes the answer itself and shows its sources: Google AI Overviews and AI Mode, featured snippets, ChatGPT search, Perplexity, Gemini and Claude.

An AEO agency is a firm that does that work for you. It measures whether AI assistants recommend you, finds the gaps that keep you out of the answer, and fixes them: clearer passages, better structure, structured data, consistent business facts across the web, and mentions in sources AI tools already cite.

AEO builds on SEO. It does not replace it. Google says a page only needs to be indexed and eligible to show in Search with a snippet to appear as a supporting link in AI Overviews or AI Mode, and that no special markup or machine-readable file is needed. A page that is not indexed cannot be quoted by anything that uses a search index.

What an AEO agency usually includes

A serious engagement covers five areas, and a proposal should name each one:

1. Measurement. A baseline of where you appear today: which questions trigger an AI answer about your topic, which sources get cited, and whether your business is named. This is usually tracked across ChatGPT, Perplexity, Gemini and Google AI Overviews, not one engine alone.
2. Technical fixes. Indexing, crawl access, page speed, internal linking and structured data, so AI tools can read and retrieve your pages. This is ordinary SEO work, aimed at AI retrieval.
3. Content that can be quoted. Direct answers near the top of a page, headings that match the question, a named source for every number, and short passages that stand alone when lifted into an answer.
4. Off-site authority. Consistent business facts across listings and directories, expert mentions, reviews and citations in sources AI tools already trust. This is the slowest part and the hardest to fake.
5. Reporting. Monthly reporting on citations, brand mentions and the questions you appear for, with the method explained. A report that only shows rankings is not an AEO report.

If a proposal lists only content production, it is a content package with a new label. If it lists only tracking, it is a tool, not an agency.

What it costs

There is no standard AEO price, and only a minority of agencies publish a rate. The published figures below come from agency pricing pages and pricing surveys in 2026, and they disagree with each other, which is itself useful information: the market has not settled.

Named examples from published pages: Botanik, a specialist AEO agency, publishes an audit from €2,670, retainers from €1,780 a month and a day rate of €890, with 15% to 25% of fees tied to results. Optimist publishes an Advisory tier from $3,000 a month and a Full Service tier from $4,000 a month, with a one-off roadmap at $7,500. Digital Elevator publishes AI visibility sprints from $3,000 and managed AEO and SEO from $3,500 a month. Omniscient Digital publishes a starting price from $10,000 a month, and NoGood reports an average retainer above $20,000 a month.

One survey, First Page Sage's 2026 pricing data, reports a median GEO and AEO retainer of $6,850 a month, 45% higher than the $4,740 median for traditional SEO retainers. Treat medians as a guide, not a quote: your price depends on site size, markets, languages and how much content the agency produces.

A worked cost calculation

Take a mid-tier retainer at $3,500 a month, the entry point for managed AEO and SEO at one published agency.

• Monthly retainer: $3,500
• One year: $3,500 × 12 = $42,000
• One-off audit before it starts, at the published Botanik figure: €2,670, about $3,100 at recent rates, paid once
• AI visibility tracking tool, if charged separately: $200 to $500 a month, or $2,400 to $6,000 a year

A realistic first-year total is therefore $42,000 for the retainer, plus a one-off audit, plus tracking if it is not included. A $2,500 a month retainer, by contrast, costs $30,000 a year, but at that level the agency is selling a focused technical audit, priority-page recommendations, basic structured data guidance and a citation-monitoring workflow, not a full content production engine or continuous engineering work. The scope should match the price, and the proposal should say what is left out.

How to vet an AEO agency

Ask these questions before you ask for a discount. A good agency answers them plainly; a weak one changes the subject.

• How do you measure AI visibility? Ask which engines are tracked, how many prompts are monitored, and how often. A method that tracks one engine is not a measurement programme.
• What is the baseline, and what counts as progress? Ask for a citation count and a brand-mention count today, and the target for month three and month six.
• Who does the work? Ask for the name and experience of the person who will work on your account, not the person who sold it.
• What is included, and what costs extra? Ask whether content production, engineering implementation, tracking tools and digital PR are inside the retainer or charged separately.
• What happens if nothing changes? Ask how the agency reports a flat month, and whether any fee is tied to results. Botanik ties 15% to 25% of fees to a contractual indicator; most agencies tie none.
• Can I see a sample report? Ask for a redacted monthly report from another client. A report that only shows rankings is not an AEO report.
• What do you need from us? Ask what access, approvals and subject-matter time the agency needs each month. An agency that needs nothing from you is not doing the work.

Also check the contract: minimum term, notice period, who owns the content, and what happens to tracking data if you leave. Optimist runs month-to-month; other agencies ask for three months on fixed-scope work and twelve months on a full campaign.

When to hire, and when to do it yourself

Hire an agency when you have a site that already ranks, a team that cannot spare the hours, and a budget of at least $3,000 a month for a focused programme. The agency's value is measurement, implementation and off-site work at a scale a small team cannot match.

Do it yourself when your site is small, your budget is under $1,000 a month, or your pages are not yet indexed and ranking. At that stage the work is ordinary SEO: fix indexing, write direct answers, add structured data and keep business facts consistent. A tracking tool from about $65 a month, plus your own time, is enough to start, and an agency retainer would spend most of its fee on work you could do in a week.

Do not hire an agency that promises guaranteed placement in ChatGPT, Perplexity or Google AI Overviews. No agency controls those choices. Do not hire one that cannot explain its measurement method, or one whose proposal is a rebranded SEO package with the word AEO added to the title.

Common mistakes

• Buying a label, not a scope. AEO, GEO and AI SEO are used for the same work by different agencies. Read the scope, not the label.
• Paying for tracking without execution. A dashboard that shows you are absent from AI answers does not put you in them. Somebody has to change the pages.
• Expecting results in a month. AI answers change as models and indexes update. A serious programme is measured over months, and a flat month is normal.
• Forgetting the foundation. A page that is not indexed cannot be cited. Technical SEO comes first, whatever the proposal calls it.
• Judging by rankings alone. A page can rank first and still not appear in the AI answer about the same query. Measure citations and brand mentions, not just positions.
