How much does an AEO audit cost for a B2B website?

Lean Labs' free baseline works from a single URL. You enter a product or service page, not the homepage, and the report generates in about 90 seconds. It scores how the brand performs in engines including ChatGPT, Claude and Gemini. Lean Labs starts every engagement with it, so the reading comes before any spending.

Software lets you repeat the measurement on prompts you choose. Otterly's pricing page lists its Lite plan at $29 a month on monthly billing. That covers 15 prompts tracked daily across ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot. It also includes up to 1,000 URL audits a month, which Otterly calls generative engine optimization audits.

Fifteen prompts is a small set. Suppose you sell three products and want five buyer questions tracked for each. That uses all fifteen. The next plan is $189 a month for 100 prompts.

The tool produces findings, and reading them is your team's work. Someone has to decide which pages matter, what the results mean for those pages and what to change. For a team with that time, $29 a month buys a measurement it can rerun every day.

Fuel Online's pricing guide gives one worked figure: $2,500 to $5,000, one time, for up to 20 pages. The fee covers reworking pages you already have with short answers, question-and-answer pairs and schema. No new articles are written. At the full 20 pages it comes to $125 to $250 a page.

Fuel Online calls its figures planning ranges for the industry and says they aren't its own package prices. The figure prices an audit and its fixes together.

Some audits stop at a report. For those, the same guide says to get findings page by page with a plan for acting on them, and to settle who makes the changes, because "a report is a different deliverable from a deployed fix."

Keep the audit price apart from the price of building what the audit recommends. Lean Labs' pricing shows the difference. The free step is the baseline scan. The first paid step is a $9,000 on-site package, charged once with the first year included, and it's a build that includes an answer hub and entity schema. So on that path the scan costs nothing and the money goes to the build.

Three quotes that all say "audit" can describe a scan, a report, or a report plus finished work. We compare project, monthly and software prices in how much AEO services cost.

Suppose your B2B site has 60 pages, and 12 of them are the product, comparison and pricing pages your sales team sends to buyers. A 20-page scope covers those 12 and leaves room for eight more. Before you sign, we'd want the statement of work to name the pages and the prompts that will be tested. It should say whether a technical review of crawling and markup is included, how the findings will be ranked, and who implements them. With those written down, two audit quotes become comparable, and you can see whether a lower quote and a higher one are pricing the same job. The rest of the selection is covered in what to look for when choosing an AEO agency.
