Answer in brief
AEO and GEO agency fees should be compared by scope, not by one market-average number. A credible proposal states the prompt cohort, engines, baseline, source analysis, content or technical work, review process, reporting cadence, and labor assumptions. Without those details, two monthly retainers are not comparable.
Pricing follows scope
An audit can be a bounded project. Ongoing monitoring, content production, technical implementation, and earned distribution are recurring operations. A proposal that combines all of them should show the expected volume and owner for each.
The number of prompts alone is not enough. Model coverage, locations, personas, run cadence, answer retention, and analyst review determine how much work the monitoring layer creates.
Ask for a unit model
Request a table showing included prompts, engines, runs, deliverables, pages, meetings, and revision cycles. Ask what triggers an overage and which work requires a new statement of work.
The goal is not to force every agency into hourly billing. It is to understand the operating assumptions beneath the retainer so that proposals can be compared fairly.
Protect the evidence and approvals
The client should be able to inspect the baseline, stored answers, citations, source gaps, briefs, and published changes. Confirm who approves factual claims and who is accountable for regulated or high-stakes content.
Generated drafts do not remove editorial responsibility. The engagement should include source checks, change logs, and a clear path for subject-matter review.
Use a 90-day proof plan
A pilot should complete the whole operating loop: baseline, opportunity selection, production, publishing, re-observation, and reporting. Define the output volume and the evidence that would justify continuation before the work begins.
Avoid contracts that guarantee placement in proprietary answer systems. A defensible promise is a documented process, complete work, and transparent measurement.
Data behind the finding
| Measure | Result | Context |
|---|---|---|
| Audit | Baseline and opportunity map | Prompts, competitors, sources, technical access, and owned content |
| Monitor | Repeated observations | Run cadence, answer engines, geographies, and evidence retention |
| Create | Content and page changes | Briefs, drafts, subject review, publishing, and QA |
| Distribute | Earned and third-party surfaces | Outreach and community work require distinct ownership |
| Report | Decisions and attribution | Executive reporting, experiments, and commercial outcomes |
No universal price benchmark is asserted because agency scope, geography, seniority, software, and production volume vary materially. The framework is designed to make proposals comparable and to surface work that would otherwise be hidden in a retainer.
