What should an agency charge for AI search optimization services?
Quick Answer: Charge for AI search optimization services with a fixed audit (one agency lists $1,500 [1]), then a retainer or add-on layer scoped by engines, prompts and deliverables, never by promised citations. Clients already on your SEO retainer get the add-on. New ones get the audit first. This is for agencies and consultants defending a quote on the first call.
Key takeaways
- Write the prompt count, the brand count and the engine list into every quote, since your workload grows with those three units.
- Bill the tracking tool on its own invoice line at what it costs you.
- Read every monthly report against the numbers the audit produced.
- Agree on content ownership and export terms before the first article goes live.
What should an agency charge for AI search optimization services?
One agency's published prices put a one-off AI search audit at $1,500 and ongoing work at $1,000 to $3,500 a month or more [1]. Constant Concepts lists a fixed-price AI Visibility Audit at $1,500 and AEO retainers starting at $3,500 a month, with monthly citation reporting included [1]. AEO stands for answer engine optimization, which the same page defines as getting chosen as the direct answer in AI Overviews, featured snippets and voice results. For clients who already run an SEO retainer with the agency, its AEO layer "adds $1,000/mo."
The same page also gives industry context of $2,000 to $10,000 a month for credible AEO retainers. Treat that as one agency's reading of the market, not a measured average. It is blunt about the low end: "anything much cheaper is usually classic SEO with a new label."
Not every agency publishes a figure. KKom's AI visibility page lists no price and invites buyers to talk with a marketing expert [2].
What you are really pricing is scope: prompts, brands, engines and deliverables. One tracking tool, Welt Analytics, defines a prompt as one tracked question and states: "The plan limit is the number of questions, not the number of engines." [3]
Set your audit, retainer and add-on prices beside these figures, and write down the scope behind any gap.
Which pricing model fits which client?
The model depends on three things: what the client already buys from you, how many brands they bring, and whether they want ongoing work at all.
| Client situation | Pricing model | What you do |
|---|---|---|
| No AI search work yet, unclear baseline | Audit, then retainer | Quote a fixed-price audit first, then propose a retainer based on the findings |
| Existing SEO retainer with you | Add-on layer | Quote the AI layer as a monthly add-on and list its deliverables |
| New client wanting full AI search coverage | Standalone retainer | Quote a monthly retainer sized to prompts, brands and engines |
| Several brands or many prompts to track | Per-brand retainer | Price per brand and by prompt volume, and itemize the tracking tool as its own line |
| Buyer wants a one-off diagnosis only | Audit alone | Sell the audit with a written findings report and no ongoing commitment |
Starting with the audit lowers the risk on both sides. The client pays a known, capped amount before committing to months of fees. The agency gets a measured starting point, so its first monthly report has something to show movement from.
What belongs in the scope of AI search optimization services?
A usable scope names four things: which engines are covered, how often each one is checked, what content and citation work happens each month, and how often the client gets a report. The mechanics of running those checks are covered in the article on how agencies track client brands across ChatGPT, Gemini, Claude and Perplexity.
Write the measures in plain terms. KKom, for example, says it tracks how often AI tools name-drop a brand, the sentiment of those mentions, and click-throughs from tools like ChatGPT and Perplexity [2].
Welt Analytics checks ChatGPT, Gemini, Google AI Overviews and Google AI Mode daily, and Claude and Perplexity weekly. Suppose a scope says only "daily monitoring." The first time a client asks about yesterday's Claude answer, you have a dispute. Prevent it with one line per engine in the scope, stating daily or weekly, so the client knows what each report can show.
Then test the quote itself:
- List every deliverable the quote covers, one per line.
- Next to each one, write the engines it covers, the prompt count and the reporting cadence.
- Mark any fee line whose value depends on an assistant citing the client.
Expected result: every fee line maps to a named deliverable, and step 3 marks nothing.
How do you price without promising results?
Price the work and the reporting, and state in writing that the outcome cannot be guaranteed. Constant Concepts puts it directly: "No one can honestly guarantee what ChatGPT or Google will cite." [1] It commits instead to measured baselines and monthly logs of citations and share of voice. It judges success by organic traffic to commercial pages, organic-driven leads and organic-driven revenue.
The mistake to avoid is a fee clause tied to citations or positions, such as a bonus per AI mention or a refund if the brand never appears. Tie the fee to scoped deliverables and a fixed reporting cadence instead, and add a contract line saying no assistant's output can be guaranteed. If the client wants one shared number to discuss each month, measure share of voice in AI answers versus competitors and report which way it moves.
Timelines need the same care. KKom says noticeable momentum usually builds over a few months [2]. Constant Concepts gives 4 to 9 months for national SEO, depending on competition. Quote both as other agencies' ranges, not as your promise.
How much of the fee should cover tracking tools?
None of your labor fee should hide the tool. Bill tracking software as its own line at what it costs you, and keep your fee for the work. If the tool sits inside the retainer, the client cannot see what is measured, what is labor, or who holds the data if you part ways. Itemize it, and state the prompt and brand limits that line covers.
Published plan prices make the line concrete. Welt Analytics lists its Starter plan at €89 a month for 50 prompts and 1 brand, and Pro at €499 a month for 400 prompts and 3 brands [4]. Its pricing page notes that prices exclude VAT, which is added where the law requires it [3].
Multi-brand clients bring a second trap. Say you quote a flat retainer to a client with four brands. Those brands can outgrow the plan you budgeted for, because brand limits change by plan. Count brands and prompts against the plan limits before you quote, and price per brand. The same data can show a client which competitors AI assistants recommend over them, which makes the tool line easy to explain.
Worked example: pricing a client with an existing SEO retainer
Say a client pays you $4,000 a month for SEO and asks for AI search work. Quoting the add-on at $1,000 a month brings the monthly fee to $5,000. That is a 25% increase ($1,000 of $4,000). A fixed $1,500 audit in month one makes the first invoice $6,500, and every month after that is $5,000.
The add-on model is the right quote here. The client already pays for SEO work that a standalone retainer would partly repeat. The audit is worth its $1,500 because it fixes the starting numbers that the add-on's reports measure from.
To build a measured tracking line into your next client quote, see how Welt Analytics reports a brand's visibility, share of voice, position, sentiment, sources and competitors in AI answers.
Questions
Should an agency publish its AI search prices?
A published starting figure filters out buyers below your floor before anyone books a call, which saves a small team time. Quoting on request suits agencies whose scope changes a lot from client to client. Either way, the written quote lists scope items and leaves outcomes out.
How do I keep the add-on from looking like a rebrand of current SEO work?
Name deliverables that the SEO retainer never included: the prompt set, the engine-by-engine log, and the content changes made so assistants can lift answers. If you cannot name one new item, the client is right to question the fee.
Will refusing a guarantee cost me the deal?
Sometimes it will, since some buyers want a certainty no agency can give. Offer the audit as a capped first step, so the client can judge your reporting before committing to a retainer.
Can the client keep the content if they leave the agency?
Put ownership and export terms in the contract. On the Growth and Pro plans, Welt Analytics writes articles and publishes them on a blog on the customer's subdomain. Its pricing page says customers can export everything while the plan is active and for 90 days after it ends [3]. Schedule the export before the final contract month.
