What is Technical SEO?
Technical SEO is like the engine under the hood of your website. While content attracts readers, technical SEO ensures search engines like Google can find, understand, and rank that content properly.
Think of it as building a house. You may have the best interior design (content), but if your plumbing (technical SEO) is faulty, no one wants to live there—or in your case, visit the site.
Why is a Technical SEO Audit Important?
A technical SEO audit is your website’s health check-up. It ensures everything behind the scenes is functioning perfectly. From crawl errors to speed issues, this audit reveals what’s slowing you down.
Would you drive your car without ever checking the engine or brakes? No? Then don’t run a website without regular technical audits.
Website Crawling & Indexing
Crawling: Search engines send out bots (like Google's spiders) to scan your site.
Indexing: Once crawled, the pages are added to Google’s database.
✅ Use tools like Google Search Console to monitor crawl stats. Ensure no important page is blocked or excluded.
Mobile-Friendliness
With more than half of global web traffic coming from mobile devices, your site must be mobile-friendly. Google uses mobile-first indexing, meaning it looks at your mobile site before the desktop version.
✅ Use Google’s Mobile-Friendly Test. ✅ Avoid pop-ups that block content. ✅ Ensure readable fonts and responsive layouts.
Site Speed Optimization
Nobody likes a slow website—not users and definitely not Google. Slow load times can lead to high bounce rates and lower rankings.
✅ Compress images without sacrificing quality. ✅ Minimize JavaScript and CSS. ✅ Use a reliable hosting provider. ✅ Enable browser caching and lazy loading.
Secure Your Site (HTTPS)
HTTPS is no longer optional. It tells your users (and Google) that your site is safe to browse.
✅ Get an SSL certificate. ✅ Redirect all HTTP URLs to HTTPS. ✅ Update internal links to reflect the secure version.
XML Sitemap Best Practices
An XML sitemap is like a roadmap for search engines. It lists all the important URLs on your site.
✅ Submit your sitemap via Google Search Console. ✅ Keep it updated. ✅ Avoid including 404 or duplicate pages.
Robots.txt File Setup
This small file tells search engines which pages to crawl and which to skip. It’s powerful, and a misconfigured file can block your entire site!
✅ Allow only necessary pages. ✅ Use disallow tags carefully. ✅ Test your file using Google’s Robots.txt Tester.
Structured Data & Schema Markup
Structured data helps search engines understand the content. It's like giving them a translator.
✅ Use JSON-LD format. ✅ Apply schema for reviews, articles, events, etc. ✅ Test with Google’s Rich Results tool.
Canonical Tags & Duplicate Content
If the same content appears at multiple URLs, search engines may get confused. Canonical tags guide them to the “main” version.
✅ Place canonical tags in the HTML head. ✅ Avoid unnecessary URL parameters. ✅ Consolidate similar pages when possible.
Fixing Broken Links
Broken links frustrate users and hurt SEO. Regularly check for:
✅ 404 errors ✅ Outdated external links ✅ Broken images or scripts
Use tools like Screaming Frog or Ahrefs to identify and fix them.
URL Structure Optimization
Clean, descriptive URLs are user- and SEO-friendly.
✅ Use hyphens to separate words. ✅ Avoid special characters. ✅ Keep URLs short and relevant. ✅ Include target keywords when possible.
