# [AEO agency pricing: compare scope and incentives](https://rebilder.com/solutions/aeo-agency)

- **Updated:** 2026-09-10
- **Description:** Compare retainers, fixed projects and performance pricing by scope, reporting method and the outcomes each agreement measures.

Choose an AEO agency around the work your business needs: reliable source information, useful answers and reporting you can act on. Compare the scope and pricing model together.



## What you get

- The three ways these engagements are priced
- How each pricing model relates to the work delivered
- How to evaluate performance pricing on citations
- The free baseline to take before any of them starts

## The three models

Compare the pricing model with the work you need. A fixed project, retainer and performance agreement assign responsibility differently; make those responsibilities explicit in the scope.

| Model | What it rewards | Fits when |
| --- | --- | --- |
| Monthly retainer | Ongoing delivery and maintenance | You need continuing content, integration or reporting work |
| Fixed project | Defined delivery under an agreed scope | The project has defined integration and content deliverables |
| Performance | Outcomes measured by the agreed method | Use a clearly defined measurement and attribution method |

A retainer should name the work that continues: source updates, changed templates, new customer questions, monitoring and follow-up fixes. Scope the initial installation separately so you can evaluate both.

## How to evaluate performance pricing on citations

Performance pricing needs a defined result, observation method and attribution window. Review those details alongside fees and responsibilities.

- **Define the observation.** Identify the prompts, platforms, dates and answer positions being sampled. Keep those results separate from site requests and referrals.
- **Attribution.** Model changes, prompt wording and other sources also affect answers. Define how the engagement will distinguish those effects from changes to your site.
- **Control.** Both parties can improve source information, but the assistant selects and presents its answer. Define the measured deliverables accordingly.

> **What the incentive actually produces** For performance pricing, agree the prompt set, model versions, sampling schedule and reporting method in advance. Make the underlying observations available to both parties.

Performance pricing needs a shared measurement method and attribution window. Define deliverables, data access and how the agreement handles platform changes and ambiguous results.

## What to do before you sign anything

1. **Take the baseline yourself.** A readability score per template, from a published deterministic spec. Free, no account, and it is your negotiating position.
2. **Define responsibilities.** Separate initial delivery from ongoing integration, content and reporting work.
3. **Define ownership and handover.** Record which code, source connections and reports remain available when the engagement ends.
4. Combine server-side request reporting with browser analytics. The gateway observes requests it handles; the Rebilder Tag records AI-referred visits and supported browser activity.

## What does an AEO agency do?

A technical half covering how your pages are served to AI agents, and an editorial half covering content that answers real questions. Technical maintenance and content development both continue as the business changes.

## How do AEO agencies charge?

Fixed projects suit defined implementations; retainers suit ongoing management. Performance agreements need clear attribution, deliverables and a measurement method both parties understand.

## Should I pay an agency per citation or mention?

Use an agreed sampling method for mentions and distinguish observed changes from attributed results. Request counts and readability checks provide additional measurements from your own site.

## What should an AEO engagement cost?

The SDK is free and self-hostable. Budget separately for integration, testing, content work and ongoing maintenance. Ask for the split in hours before comparing quotes.
