Web design agencies should compare SEO proposals by the work that creates cost, not by a single monthly figure. The most useful breakdown is search-market difficulty, the amount of page and content work required, and the authority promotion needed to support priority services. A proposal should explain how labor and responsibility are divided across those areas so you can see what the retainer is buying.
Search Market Breadth
Competing in one genuine operating market is a different assignment from pursuing several metros or non-local commercial queries. The existing editorial states that competitive metro markets can require 2-3x the content and link volume of smaller regional markets for comparable positions. Because the source JSON does not contain a supporting source URL for that benchmark, treat it as previously published planning guidance that still needs source reconciliation, not as a universal relationship. Ask for the target query set, current visibility, competing pages, and the reason the proposed effort matches your actual market.
Pages, Content, and Implementation
Cost rises when the provider must research, write, edit, publish, internally link, and maintain assets rather than simply advise your team. A web design agency might need stronger service pages, case-study support, comparison pages, educational resources, or location pages only where a genuine location can support useful location-specific information. A program that creates and improves assets every month should therefore be evaluated differently from a scope limited to recommendations on existing pages.
Authority Promotion and Outreach
Authority work can involve digital PR, partner outreach, or editorial pitching, but the budget should be tied to the process rather than an implied placement count. Confirm the research performed, the approval criteria, quality controls, any separate third-party charges, and how outcomes are documented. A proposal should not imply that every outreach action produces a link or a ranking change.
Use these scope categories to evaluate whether technical work, content work, and authority work are proportionate to your agency's needs. Comparing the same categories across providers prevents a narrow proposal from looking artificially cheaper than a broader one.
