How I Run a Full Technical SEO Audit (Start to Finish)
Last Updated on December 12, 2025 by Corey Fox
Overview
A technical SEO audit is the foundation of every growth system I build. If your site cannot be crawled, indexed, or understood by search engines, no amount of content or backlinks will help.
This post breaks down my exact process, step by step.
The Problem
Most businesses are unaware of hidden technical issues that limit their visibility.
These issues include:
• Crawl errors
• Slow loading
• Bad mobile performance
• Redirect chains
• Missing schema
• Thin or duplicate content
• Poor internal linking
These problems create long-term damage if not addressed.
My Approach
I treat technical SEO like diagnosing the engine of a car.
Fix the underlying structure and everything else becomes easier.
My Technical SEO Audit Process
1. Full Site Crawl (Screaming Frog)
I pull data on:
• Broken links
• Server errors
• Redirect chains
• Meta data
• H1 and H2 structure
• Duplicate pages
• Indexation logic
• Canonical tags
This gives me a full technical map of the site.
2. Core Web Vitals Review
Using PageSpeed Insights, I inspect:
• LCP
• CLS
• FID
• Render blocking elements
• Image delivery
• Server response time
If a site loads slow, users bounce and rankings drop.
3. Indexation and Crawlability
Inside GSC, I check:
• Index coverage
• Crawl anomalies
• Blocked URLs
• Submitted vs indexed
• Sitemaps
• Robots file logic
Search engines need a clear path.
4. Schema and AEO Optimization
I review schema types:
• Organization
• FAQ
• Article
• Service
• LocalBusiness
Plus, I map entities and content relationships for AI Overviews.
5. Internal Linking System
I build or repair:
• Anchor text flow
• Topic clusters
• Supporting pages
• Silo structure
This improves topical authority.
Tools Used

Result
A complete diagnosis of everything blocking growth, plus a roadmap of precisely how to fix it.
Final Thoughts
The most successful SEO systems start with clarity.
A technical audit gives you that clarity, and the confidence to scale content, ads, and funnels with a clean foundation.
