A full technical SEO audit typically costs between $1,500 and $10,000, depending on site size, complexity, and how deep the analysis goes. Small business sites with under 500 pages often fall in the $1,500 to $3,500 range. Mid-size sites with thousands of pages, multiple content types, or e-commerce catalogs usually run $4,000 to $7,000. Enterprise sites with hundreds of thousands of URLs, international targeting, or complex JavaScript frameworks can push past $10,000. At Peak Marketing, most audits for small and mid-size businesses land between $2,000 and $5,000, scoped around the specific technical issues a site is dealing with rather than a flat, one-size-fits-all rate.
That price range exists because a technical SEO audit is not one task. It’s a bundle of separate diagnostic processes, each requiring different tools, different expertise, and different amounts of time.
What Actually Drives the Price
Site size is the first variable. Crawling and analyzing 200 pages takes a fraction of the time it takes to review 50,000. Crawl budget issues, orphaned pages, and duplicate content problems all scale with page count, and so does the labor required to catch them.
Platform complexity matters just as much. A straightforward WordPress site with a handful of plugins is far easier to audit than a custom-built e-commerce platform with faceted navigation, dynamic URL parameters, and JavaScript-rendered content. Sites built on React or Angular require rendering checks that static HTML sites don’t need, since search engines can struggle to crawl and index content that loads client-side.
International or multi-location sites add another layer. Hreflang implementation, duplicate content across regional subdomains, and localized schema markup all take extra time to verify. A law firm with offices in three states needs a different audit scope than a single-location dental practice.
History also plays a role. A site that’s changed CMS platforms, been through a domain migration, or accumulated years of redirects and legacy URLs will have more to untangle than a site built five years ago and left largely alone.
What a Full Audit Actually Includes
A genuinely comprehensive technical SEO audit covers several distinct areas, and skipping any of them leaves real problems undiscovered.
Crawlability and indexation come first. This means checking robots.txt directives, XML sitemap accuracy, canonical tag implementation, and whether Google is actually indexing the pages meant to rank. It’s common to find sites where important pages are accidentally blocked or where thin, low-value pages are eating crawl budget that should go elsewhere.
Site architecture and internal linking get evaluated next. Search engines rely on internal links to understand which pages matter most. A flat architecture where every page is one click from the homepage sends a different signal than a deep, poorly linked structure where key pages sit six clicks deep.
Page speed and Core Web Vitals require their own diagnostic pass. Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint all factor into how Google evaluates page experience. Slow-loading images, render-blocking scripts, and bloated third-party tags are frequent culprits, and fixing them often takes developer involvement beyond what an audit report alone can solve.
Mobile usability, HTTPS security, and structured data implementation round out the core technical checks. Schema markup errors are especially easy to miss because a page can look fine to a human visitor while still throwing validation errors that keep it out of rich results.
Duplicate content and URL parameter issues get their own review, particularly on e-commerce sites where filtering and sorting options can generate thousands of near-identical URLs. Left unaddressed, this dilutes ranking signals across pages that are all competing against each other instead of against outside competitors.
Why Cheap Audits Often Cost More Later
A $200 audit generated by an automated tool with no human review will surface surface-level issues, missing tags, broken links, slow load times, but it won’t explain which issues actually matter for that specific site or in what order to fix them. Prioritization is often the most valuable part of an audit, and it’s the part that automated tools skip entirely.
Sites that skip a proper audit and rely on tool-generated checklists tend to end up fixing the wrong things first. A business might spend weeks optimizing image alt text while a robots.txt misconfiguration is blocking their most important service pages from being crawled at all. The cheap audit didn’t lie about the alt text issue. It just never surfaced the bigger problem, or buried it in a 40-page report with no guidance on what to tackle first.
How to Know What You’re Actually Paying For
Before agreeing to any audit price, ask what deliverable comes at the end. A real audit produces a prioritized list of issues ranked by impact and effort, not just a raw data dump from a crawling tool. It should include specific recommendations tied to the site’s actual content management system and hosting setup, not generic advice that could apply to any website.
It’s also worth asking who performs the manual review. Tools like Screaming Frog, Ahrefs, and Google Search Console generate the raw data, but a qualified SEO strategist needs to interpret that data against the site’s business goals. A site selling industrial equipment has different priorities than a personal injury law firm, even if both have identical technical scores in an automated report.
For businesses trying to figure out where their own site stands before committing to any spend, Peak Marketing offers audits scoped to the actual size and complexity of the site in question, with pricing based on what the site needs rather than a flat package. A quick conversation about site size, platform, and current pain points is usually enough to get an accurate quote and a clear sense of what problems are worth solving first.
