Choose an SEO firm by the problem it can diagnose, the work it will deliver, and the evidence you will use to evaluate that work. A useful proposal connects your customers' needs to specific website improvements, names the people responsible, and explains how you retain control of your accounts and content.
Define the problem before requesting a price
Write a one-page brief covering your customers, services or products, locations, website platform, and desired business outcome. “Help people find the right replacement part and complete an order” provides more direction than “increase traffic.” List known problems: missing product information, confusing navigation, an upcoming migration, or pages that search engines cannot access.
Identify who can implement changes. An audit may be valuable, but it leaves work pending if nobody can fix templates, write copy, or update product data. Ask bidders to separate diagnosis, implementation, content production, and continuing support. State the staff time and technical access you can provide.
Google's guidance on hiring an SEO recommends examining experience, proposed methods, expected results, and how success is measured. It also explains that paying for Google advertising does not buy organic ranking. Use official guidance to assess consequential recommendations, including claims about visibility in AI search features.
Request evidence you can inspect
| Area | Ask for | What a useful answer contains |
|---|---|---|
| Diagnosis | A sample finding | Affected URL, observed problem, evidence, proposed repair |
| Delivery | A first-phase work list | Owner, dependency, acceptance check, estimated effort |
| Measurement | A sample report | Definitions, baseline, date range, business outcomes, limits |
| Access | An account and permissions plan | Your ownership, named user access, approval and revocation process |
| Content | Editorial responsibilities | Subject review, source verification, rights, final approval |
| Exit | A handover description | Files, change log, accounts, documentation, remaining obligations |
Ask for comparable work with context: site type, starting condition, period, and what the firm actually changed. A chart without a baseline or explanation of concurrent advertising and seasonal changes offers little basis for comparison. Request references the firm has permission to share.
Have the firm explain any proposed link acquisition, scaled content production, or automated changes. Google identifies link schemes and mass search-engine submission pitches as warning signs. Treat an unexplained guarantee of a particular position as a reason to ask exactly what is being promised, for which query and result type, and how the claim can be substantiated.
Compare two fictional proposals
Use the SEO proposal review worksheet to record each response, unresolved question, responsible person, and acceptance condition. Agree budget and scope changes in writing. Keep the domain, analytics, search-console, advertising, and content accounts under the business's control, with appropriately limited individual access for contractors.
Review delivery and outcomes separately
A completed repair can be checked promptly: the page answers the compatibility question, its links work, and its intended content is accessible. Business outcomes need a defined observation period and comparable data. Ask the firm to report delivered changes, the reasons for them, and what happened afterward in separate parts of the report.
Compare relevant inquiries, qualified leads, or completed orders alongside search impressions and clicks. Record tracking changes, promotions, seasonality, and stock availability that may affect interpretation. Treat ranking reports as a limited view of particular queries and conditions. An increase following a change suggests a question to investigate; it alone establishes no causal attribution.
Schedule a scope review with specific decisions: continue a useful activity, correct a failed assumption, or hand work to your team. For the underlying reader experience, use navigation testing; for interpreting external interest, use web search trends.
