A technical SEO audit finds and fixes the infrastructure problems that stop everything else working: pages Google cannot crawl or index, canonical conflicts, redirect chains, index bloat, and Core Web Vitals failures.
A technical SEO audit evaluates how search engines discover, render, index and trust your site – separate from content quality. If Google cannot reach or store your pages, no amount of content or link building will help.
That is why technical SEO comes first in the SEO audit order.
Google Search Console (indexing, Core Web Vitals) and the free website audit tool cover most checks. A crawler (Screaming Frog, Sitebulb) helps on larger sites.
How to run a technical SEO audit
Fix in the order that avoids wasted work.
Baseline
Run the free audit and PageSpeed on your priority templates.
Separate blockers
Distinguish what blocks indexing from what only slows the page.
Fix in order
Crawl access to indexing to architecture to speed to schema.
Re-test
Check the rendered page and crawl paths after each change.
Hand off
Give developers precise notes for anything that needs code.
Technical SEO services
If the crawl, index or speed problems are systemic, GSA’s Rebuild fixes them and verifies the rendered result – site speed, Core Web Vitals, index bloat and canonical loops – from $1,999.
Frequently asked questions
How much does a technical SEO audit cost?
Technical-only audits run roughly $500-$5,000 from consultants and agencies, more with log-file analysis. Our free tool covers the most common checks at no cost.
Can I fix technical SEO myself?
Many items yes; some need a developer or hosting access. The audit tells you which is which.
How often should I run a technical audit?
Quarterly, and always after a redesign, migration or CMS change.
A small site does not need a giant warning list before it can act. Start with access, indexability, important templates, critical links and the issues most likely to block a useful page.
Separate blockers from advisories.
Inspect representative templates.
Verify the rendered page after a fix.
Keep performance and ranking claims separate.

A focused technical audit checklist for a small site
A focused audit can cover access, response behavior, indexability, canonical signals, internal links, templates and performance without pretending to inspect every possible implementation detail.
Fix access and response issues first.
Check canonical and index signals on important URLs.
Inspect internal discovery and template consistency.
Re-run the same scope after a meaningful change.
Evidence boundary: This guidance explains how to inspect and decide. It does not guarantee rankings, traffic, leads, sales or revenue.
A technical SEO audit is a bounded inspection of what search engines can crawl, render and index. It is not a content rewrite and it is not a ranking promise.
Crawl and indexation: robots.txt, noindex, canonical tags, sitemap inclusion and orphan pages.
Page response: status codes, redirect chains, broken internal links, HTTPS and mixed content.
Rendering: title, H1, structured data, JavaScript dependencies and mobile viewport.
Architecture: internal link depth, duplicate URLs, parameter handling and pagination.
Who it is for
Business owners who have published pages but cannot explain why some are not indexed, why a page returns the wrong canonical, or why the same content appears under several URLs. It is also useful before a migration or a redesign.
What you get
A dated list of findings with the URL, the evidence and the fix. Every item is marked as an error, a warning or a deliberate exception. You also get a re-check date and the scope that was crawled.
What it does not promise
It does not guarantee rankings, traffic or revenue. It does not replace a content strategy, and it does not “fix” a page by adding keywords. The audit tells you what is technically wrong; the business decision remains yours.
