Technical SEO Audit
What Is a Technical SEO Audit?
A thorough technical SEO audit analyzes the essential framework of your website.
The goal is to uncover and fix issues that prevent search engines from properly crawling, indexing, and ranking your content.
This process is essential to ensure your site performs at its best—and it should be part of every comprehensive SEO strategy.
Why a Technical SEO Audit Is Important
Here’s why a technical SEO audit matters:
- Ensures search engines can access your site
- Improves page speed and mobile usability
- Fixes crawl errors and broken links
- Helps comply with Google’s algorithm guidelines
- Provides a better user experience
Ignoring technical SEO means missing out on rankings your content deserves.
Step-by-Step Technical SEO Audit Guide
Let’s break down how to perform a thorough technical SEO audit.
1. Check Crawlability and Indexability
Search engines must be able to access your website’s content in order to evaluate and rank it.
✅ Leverage tools such as Google Search Console and Screaming Frog to:
- Analyze robots.txt and XML sitemaps
- Find crawl errors or blocked pages
- Detect noindex tags and canonical tag issues
Make sure important pages are discoverable and indexed.
2. Audit Site Speed and Performance
Site speed directly impacts both SEO and user experience.
✅ Use these tools:
- Google PageSpeed Insights
- GTmetrix
- WebPageTest

3. Test Mobile-Friendliness
Google uses mobile-first indexing, so your site must work well on all devices.
✅ Use the Checking Mobile-Friendliness tool to evaluate:
- Responsive design
- Touch target sizes
- Readable fonts and layouts
- Proper viewport configuration
A mobile-friendly site ensures better rankings and usability.
4. Review Site Architecture and URLs
✅ Your website structure should be:
- Organized in a flat hierarchy
- Easy to navigate (logical internal links)
- Using SEO-friendly URLs (short, descriptive, hyphenated)
This makes it easier for search engines to crawl and for users to find information.
5. Analyze Structured Data and Schema Markup
Adding schema helps search engines understand your content.
✅ Evaluate your site’s content with tools like Google’s Rich Results Test and Schema.org validator.

Make sure:
- You’re using the right schema types (e.g., Article, FAQ, Product)
- Your markup is valid and error-free
- Important content (e.g., reviews, breadcrumbs) is enhanced with schema
6. Fix Broken Links and Redirects
A site with broken links can frustrate users and reduce its visibility in search engine results.
✅ Use Screaming Frog or Ahrefs to:
- Find 404 errors and internal broken links
- Identify redirect loops or chains
- Ensure all redirects are 301 (not 302)
Clean up your links regularly to keep your site healthy.
7. Secure the Site With HTTPS
Search rankings are positively impacted by security measures, which also enhance user trust.
✅ Confirm your site:
- Uses an SSL certificate
- Redirects all HTTP URLs to HTTPS
- Shows no “mixed content” warnings
8. Review Duplicate Content and Canonicals
Duplicate content can dilute ranking power.
✅ Look for:
- Repeated meta titles and descriptions
- Similar content across pages
- Missing or incorrect canonical tags
Using proper canonicalization enables search engines to select the correct page version for ranking purposes.
9. Monitor Core Web Vitals
Core Web Vitals impact your site’s performance scores.
✅ Track:
Monitor this via Google Search Console or Lighthouse reports.
