How to Do a Technical SEO Audit: A Beginner's Guide

A technical SEO audit sounds intimidating, but it's really just a structured health check of your website. Skip it, and even great content can fail to rank. Here's a clear, beginner-friendly walkthrough.

Why technical SEO matters

Search engines must be able to crawl, render, and index your site before they can rank it. Technical issues — slow speed, broken links, blocked pages — quietly sabotage everything else you do. Fixing them unlocks your content's full potential.

1. Check crawlability

Make sure your robots.txt isn't blocking important pages, and that your key pages are actually indexed. Google Search Console's Pages report shows you what's included and what's excluded.

2. Submit an XML sitemap

A sitemap helps search engines discover all your pages. Most platforms generate one automatically — submit it in Search Console.

3. Test site speed and Core Web Vitals

Run your top pages through PageSpeed Insights. Aim to pass the three Core Web Vitals (LCP, CLS, INP). Compress images and remove unnecessary scripts to improve.

4. Confirm mobile-friendliness

Google indexes mobile-first. Check that every key page is fully responsive and easy to use on a phone.

5. Fix broken links and errors

404 errors and broken links waste crawl budget and frustrate visitors. Find and fix or redirect them.

6. Verify HTTPS and canonicals

Ensure your site runs on secure HTTPS, and use canonical tags to avoid duplicate-content confusion.
