What Does an SEO or AEO Audit Cost in 2026?

Stefka Team October 12, 2026 7 min read

A single-page AEO audit is sold for $5 on the first page of Google's results. A single click on the term seo audit agency costs an advertiser $148.72. Both figures were measured on 12 October 2026. The product is thirty times cheaper than the click that sells it.

That is the useful way into this question, because the published price range for an audit is wide enough to be meaningless on its own. What the spread actually tells you is that "audit" covers two unrelated products.

How much does an SEO audit cost?

Here is everything with a published price that we could verify on 12 October 2026, alongside the advertising cost of the terms people use to find them.

The $148.72 is the number to sit with. It is the highest cost per click we have measured anywhere in this category — higher than ai visibility tools at $60.81, higher than aeo agency at $49.53, higher than fractional cmo at $31.91. And it sits on a term with a competition index of only 16, which means few advertisers are bidding and the ones that are, are bidding hard.

Firms do not pay $148.72 for a click that leads to a $5 product. They pay it because the audit is the front door to a retainer.

So what should you actually pay?

For a B2B SaaS site of roughly 50 to 500 pages, a competent audit — technical, content and citation measurement, with a ranked findings list — sits in the low thousands. Below about a thousand you are buying an automated scan with a human covering letter. Above five figures you are buying a site far larger than this, or a research project.

Three things move the number, and none of them is the number of pages:

Whether citation measurement is included. The technical and content checks are largely automatable. Finding out what ChatGPT, Perplexity and Google's AI currently say about you and your competitors, across a prompt set that matches real buyer questions, is not. It is the half that takes human judgement, and it is the half that tells you what to do.

Whether the findings are ranked. An unranked list of 120 issues is a crawler export. Ranking them means someone has decided what will move and what will not, and is prepared to be wrong in public.

Whether anyone is accountable for the result. An audit that ends at the document is cheaper than one whose author expects to be asked about it in a quarter.

The 25-point checklist sets out what a complete scope covers, which is the list to hold any quote against.

Why are so many of them free?

Because for most of the firms ranking, the audit is the advertisement rather than the product.

Of the eighteen organic results Google returned for aeo audit on 12 October 2026, fourteen sell a tool or a free scan. Only three explain the method. Google's own AI Overview above them cites ten sources, six of which are audit products citing their own marketing pages, and two of which are software directories listing a single product.

None of that makes the free tools useless. An automated scan is a genuinely efficient way to find blocked crawlers, broken canonicals and missing structured data, and you should run one before paying anyone for anything. What it cannot do is tell you whether an AI engine would choose you — and the Reddit thread Google's own AI cites in that same answer makes the complaint better than we can: schema and FAQs are table stakes, and they say nothing about why a model would pick you.

The practical move is to use the free scan for the technical layer, then pay only for the measurement layer. That is a smaller purchase than most proposals assume.

What should the deliverable contain?

Five things. Ask for them by name before you sign, because all five are cheap to promise and visible to check afterwards.

1. A ranked list of findings, each with an owner, an effort estimate and an expected effect.
2. The evidence behind each finding — the URL, the prompt, the pull, the date.
3. A baseline measurement you can re-run, with the prompt set written down so the same questions get asked next quarter.
4. A competitor comparison on the same prompts. Your own numbers mean little without them.
5. A stop list. What you are currently doing that is not worth continuing. An audit that only adds work has not made a decision.

What should make you suspicious is a score. A number between 0 and 100 is a marketing device: it is designed to be low enough to worry you and vague enough to be unfalsifiable. Several of the tools ranking for this term lead with one.

Is an audit worth buying at all?

Sometimes not, and it is worth saying so.

If you already know your positioning, your technical setup is sound and you simply have not published anything for AI engines to cite, an audit will tell you that at some expense. The money is better spent on the publishing.

An audit earns its fee when you do not know why something is not working — when the pages exist, the site is fine, and the answers still name other people. That is a diagnostic problem, and it is the case where guessing is more expensive than measuring. It is also where answer engine optimization as a discipline starts: with a measurement, not a tactic.

If what you actually need is someone to own the decision rather than document it, that is a different purchase: what a fractional CMO costs covers it, and agency, freelancer or in-house covers who should run the audit itself. The the technical checks are the part you can always do yourself first.

Where Stefka fits

We publish our price, which in this category is unusual enough to be worth saying: engagements start at €5,000 a month, and a standalone audit is scoped and quoted before it starts, against the deliverable list above.

We also publish our own numbers, including the unflattering ones — fifteen ranking US keywords and one monthly organic visitor at the last measurement, and zero genuine AI mentions. Anyone selling you visibility should be willing to show you theirs.
