How to Conduct a Full Technical SEO Audit (Step-by-Step)

 

Introduction: Why Technical SEO Matters in 2025

In the fast-evolving world of digital marketing, Technical SEO is the unsung hero behind every high-ranking website. While content and backlinks often get the spotlight, the technical foundation of your website ensures that search engines can crawl, index, and rank your pages effectively.

If your site is slow, poorly structured, or riddled with errors, it doesn't matter how great your content is — Google won’t rank you. That’s why conducting a thorough technical SEO audit is no longer optional — it’s essential.

At Delloweb, we help businesses uncover hidden SEO blockers through detailed technical audits. This guide will walk you through a step-by-step process to perform your own.

Step 1: Start with a Site Crawl

The first step in any technical SEO audit is to crawl your entire website using tools like Screaming Frog, Sitebulb, or Ahrefs.

What to Look For:

  • Broken links (404 errors)

  • Redirect chains or loops

  • Duplicate content

  • Incorrect canonical tags

  • Missing meta titles and descriptions

🔧 Tip: Proper website crawlability is key to making sure search engines can access your pages.

Step 2: Analyze Site Architecture

A clean, logical site architecture supports both users and search engines. Ensure that your website has a flat architecture, where no page is more than 3 clicks away from the homepage.

Site Architecture SEO Checklist:

  • Organized URL structure

  • Consistent internal linking

  • Clear navigation menus

  • XML sitemap is clean and updated

📌 Implementing solid site architecture SEO principles enhances both crawlability and user experience.

Step 3: Fix Indexability Issues

Even if your pages are crawlable, they may still be blocked from indexing. This means search engines can see the page, but won’t show it in search results.

Check the Following:

  • Robots.txt file: Make sure important pages are not blocked

  • Noindex tags: Remove these from pages that should rank

  • Canonical tags: Avoid incorrect or conflicting tags

  • Duplicate URLs: Consolidate them using 301 redirects

❗ Solving indexability issues is critical for improving visibility and rankings.

Step 4: Optimize Core Web Vitals

Google has emphasized page experience as a ranking factor. This includes metrics like load time, interactivity, and visual stability.

Metrics to Audit:

  • Largest Contentful Paint (LCP) – Measures load speed

  • First Input Delay (FID) – Measures interactivity

  • Cumulative Layout Shift (CLS) – Measures layout stability

💡 Follow SEO best practices like compressing images, reducing scripts, and enabling lazy loading to boost Core Web Vitals.

Step 5: Review Technical SEO Elements for Developers

For more advanced audits, SEO for developers becomes essential. Developers play a vital role in making a site SEO-friendly from the code level.

Developer-Focused Fixes:

  • Optimize JavaScript rendering

  • Implement structured data/schema markup

  • Ensure mobile-first design principles

  • Enable GZIP and browser caching

  • Use clean, semantic HTML

👨‍💻 Delloweb’s team works closely with developers to ensure the site’s code supports technical SEO performance.

Step 6: Monitor and Maintain

A technical SEO audit isn't a one-time task. Set up monitoring tools to catch issues early and maintain performance.

Recommended Tools:

  • Google Search Console

  • Google PageSpeed Insights

  • GTmetrix

  • Screaming Frog SEO Spider

  • Ahrefs Site Audit
