Between $29 a month and enterprise contracts, depending on which of three jobs you are buying.
Standalone AI visibility monitoring runs $29 to $500 plus per month. Content agents run subscription tiers from roughly $20 to a few hundred.
Execution and full-platform agents price as platform subscriptions, sometimes with usage metering on completed work.
The number matters less than the model behind it, because in this category the pricing model tells you what the product really is. This page gives the real ranges, then the one test that separates fair pricing from a taxi meter.
What the market charges today
An AI search agent (also called an AI SEO agent) prices by its category:
Monitoring agents. Otterly from about $29 a month, Peec AI from about €89, Profound from about $99 climbing steeply into enterprise tiers.
You are paying for scan volume: how many prompts, how many platforms, how often. Watch for double-paying: if your main platform already scans AI visibility, a standalone monitor may be a second subscription for the same answer.
For a full breakdown of vendors in each category, see the roundup of the best AI SEO agents.
Content agents. Standard SaaS tiers, roughly $20 to $300 a month by volume.
You are paying for production capacity. The hidden cost is not on the invoice: undifferentiated output that AI platforms learn to ignore is paid twice, once in subscription and once in results.
Execution and full-platform agents. Platform subscriptions, and this is where pricing models diverge in ways that matter more than the sticker.
Some price per seat. Some price flat tiers with “unlimited” language.
Some, ours included, price a platform subscription plus metered charges for completed work. Serena is included in every Rankability plan, with credits for executed work; diagnostics and conversation are never metered.
The three pricing models, and what each one incentivizes
- Per seat. A tell, not just a price. Agents are not seats; nobody prices an employee by how many people are allowed to talk to them. Per-seat pricing usually means the “agent” is a copilot UI on a tool.
- Flat unlimited. Reads generous, but ask what “unlimited execution” means for verification. Unlimited usually means unverified; nobody offers unlimited work they have to stand behind.
- Subscription plus metered work. The model that aligns incentives when, and only when, four rules hold: the cost of any job is shown before you approve it, checking and diagnostics are free, failed or reverted work is never billed, and hard caps exist that the agent cannot exceed.
The mental model that makes the third one make sense: salary and expenses. The subscription is the agent’s salary: on staff, always available, talk all you want.
Metered work is the expense account: when real jobs run, they draw down, with receipts. Every agency already runs this model with human staff, which is why it feels fair the moment it is framed honestly.
**A tool prices access. An agent prices work.
And an agent that can surprise you on a client site should never be able to surprise you on an invoice.**
The comparison that actually matters: not tool vs tool, agent vs labor
The sticker comparison (this agent is $99, that one is $199) misses where the money is. Price the agent against the labor it absorbs.
From the DIY stack math: gluing tools to chatbots costs an agency three to five hours per client per month in export-paste-implement-verify work, which at ten clients is $1,500 to $2,500 a month in loaded senior time before any subscription fees. A verified batch of technical fixes replaces an hour or more of a $50 to $100 an hour specialist, every time it runs.
Run that math per client, not per subscription. An agent that completes verified work worth more than its total cost pays for itself, and you can audit the claim line by line if the agent shows receipts.
If it does not show receipts, the price is not the problem. We ran the full cost model for a ten-client agency in Ahrefs + ChatGPT vs an AI SEO agent.

Hidden costs to check before you sign
- The cancellation test. If changes were applied through a JavaScript overlay, cancel and they vanish. The subscription was rent, and the real price includes redoing everything at exit.
- The re-explain tax. Agents without joined data make you carry context to them every session. That is labor, and it scales with clients.
- Verification debt. An agent that executes without verifying converts its errors into your emergency hours. Cheapest line item, most expensive failure mode.
- The monitoring double-pay described above.

FAQ
How much does an AI SEO agent cost?
Standalone monitoring: roughly $29 to $500 plus per month. Content agents: $20 to $300.
Full platforms with execution: platform subscription, with the honest ones metering completed work on top, showing the price before approval, and never billing failed work.
What pricing model should I look for?
Subscription plus metered verified work, with four non-negotiables: price shown before approval, free diagnostics, no charge for failed or reverted work, and hard budget caps the agent cannot exceed. Be suspicious of per seat (agents are not seats) and of unlimited execution (unlimited usually means unverified).
Is an AI SEO agent worth it for a small agency?
Do the labor math: hours per client per month spent operating tools, implementing changes, and assembling reports, times your loaded rate. Past a handful of clients that number usually dwarfs every subscription in this article.
Below it, a DIY stack may genuinely be cheaper — we wrote honestly about when that is true in Ahrefs + ChatGPT vs an AI SEO agent.
Are there hidden costs with AI SEO agents?
Four common ones: changes that disappear on cancellation, context you must re-supply every session, unverified errors that become your emergency hours, and paying twice for AI monitoring you already have. All four are detectable in a demo if you ask.
