What a technical SEO audit actually costs and why the range is so wide
Most businesses have seen the cheap version: an agency runs your URL through a tool like Semrush or Ahrefs, exports the 200-issue report, and sends it as your "audit." This has value as a starting point. It does not have value as a delivered outcome because 200 unranked, unexplained issues give you no way to know what to fix first or how.
A real technical SEO audit has two components: diagnosis (finding the issues) and triage (ranking them by impact). The second component is what most automated reports skip entirely.
The three things that drive audit cost
Website size: A 20-page brochure site can be manually crawled, reviewed, and reported on in a few hours. A 500-page e-commerce site requires tool-assisted crawling, segment-by-segment analysis, and significantly more time to produce a useful prioritised report.
Platform complexity: A static HTML site has straightforward technical issues or does not, if it was built well. A WordPress site with 15 plugins, a WooCommerce store with dynamic filters, or a Next.js application with complex JavaScript rendering each require different diagnostic approaches and different fixes.
Depth of deliverable: An audit that produces a numbered list of issues with severity ratings and specific fix instructions for a developer is worth more and costs more to produce than one that produces a score and a generic recommendation list.

What a proper audit deliverable includes
The deliverable from a full technical audit should contain:
Executive summary: 3 5 most critical issues explained in plain language, with estimated impact of fixing each.
Prioritised issue list: Every issue categorised as Critical (fix immediately), High (fix this week), Medium (fix this month), or Low (ongoing improvement). No 200-item undifferentiated list.
Specific fix instructions: Not "fix your canonical tags" "Add to the of each service page. Currently, 43 pages have no canonical tag and 12 have canonicals pointing to the HTTP version instead of HTTPS."
Before/after tracking plan: The metrics to monitor after fixes are implemented, so you can measure improvement rather than assume it.
