Medical spa SEO can be structured in three commercial models. The decision should follow the work required, the duration of that work, and how responsibility is allocated, not a preference for the lowest headline fee or the most aggressive promise six months out.
Monthly Retainer
A retainer is the most common arrangement and, for most practices, the most appropriate: it funds recurring work. Typical inclusions can cover technical monitoring, content updates or production, internal linking, local SEO, digital PR or link acquisition, reporting, and coordination. The proposal should also list exclusions such as web development beyond an agreed allowance, paid media, photography, legal review, medical review, or major migrations so the practice can compare like with like.
The retainer range is $1,500-$5,000/month (industry estimate). Single-location practices in mid-size markets with limited competition often start around $1,500-$2,500, while multi-service practices in dense metro areas with strong competitors tend to require $3,000-$5,000 or more to move the needle. That retainer range sits alongside the $2,500-$12,000 per month 2026 pricing for the category, which runs from single-location practices in mid-market cities to multi-location groups in saturated metros. Require the provider to explain the actual labor, deliverables, tools, review burden, and dependencies behind the quote.
Project-Based or One-Time Audit
Project pricing fits bounded work: a technical audit, migration review, one-time content remediation, analytics setup, or defined Google Business Profile correction. The statement of work should identify the starting evidence, deliverable, owner, acceptance criteria, remediation boundary, and whether implementation is included or priced separately.
Audits run $500-$2,500, and larger build-out projects can run $3,000-$8,000 depending on scope (industry estimate). A one-time project is not a substitute for ongoing SEO: it solves a defined problem and ends when the agreed deliverable is validated, while recurring optimization is a separate purchasing decision.
Important: distinguish diagnosis from execution. A report that identifies defects is not the same scope as fixing, testing, monitoring, and maintaining them.
Performance-Based Pricing
Performance pricing transfers part of the commercial risk, but performance agreements often define success narrowly and can incentivize shortcuts that create long-term problems. The contract should define the metric, data source, attribution window, target geography, treatment of branded queries, lead quality, duplicate leads, tracking loss, seasonality, and whether payment depends on rank, traffic, qualified inquiries, or another outcome. A rank #1 for one keyword is not automatically equivalent to useful patient demand.
Before agreeing, document exactly what triggers payment, who controls the measurement account, how disputes are resolved, and what happens when search algorithms, tracking systems, site changes, or business operations alter the observed metric outside the provider's direct control.
