Technical SEO Basics - Optimizing Your Website Behind the Scenes

June 26, 2025

What is Technical SEO?

Technical SEO is the process of optimizing your website’s infrastructure to help search engines crawl, interpret, and index your pages more effectively.

It’s not about content or keywords - it’s about making sure your site performs well technically, so your valuable content can actually show up in search results.

Why Technical SEO Matters

  • Ensures your site is accessible to search engines
  • Improves user experience through speed and responsiveness
  • Reduces crawl errors and indexing issues
  • Increases your chances of appearing in rich results and core web vitals rankings

Even the best content can fail to rank if search engines can’t properly access it.

Key Elements of Technical SEO

1. Crawlability & Indexing

  • Make sure search engines can crawl your pages via a clean robots.txt file
  • Use a sitemap.xml to list important URLs
  • Avoid duplicate content with proper canonical tags
  • Use noindex tags for pages you don’t want to appear in search

Tools: Google Search Console, Screaming Frog

2. Mobile-Friendliness

  • Use responsive design that adapts to all screen sizes
  • Avoid elements that break on mobile (e.g., popups)
  • Test your site with Google’s Mobile-Friendly Test

3. Site Speed

  • Compress images (use WebP or lazy loading)
  • Minify HTML, CSS, and JS
  • Use caching and fast, secure hosting
  • Aim for Core Web Vitals targets (LCP, FID, CLS)

Tools: Google PageSpeed Insights, GTmetrix, Lighthouse

4. Secure Connection (HTTPS)

  • Always use an SSL certificate
  • Redirect HTTP traffic to HTTPS
  • Search engines may rank HTTPS pages higher and warn users about insecure sites

5. URL Structure

  • Keep URLs clean, descriptive, and keyword-rich
  • Avoid long strings, unnecessary parameters, or session IDs

Example:
(correct) /seo-checklist
(incorrect) /page.php?id=1234&cat=seo

6. Structured Data (Schema Markup)

  • Helps search engines understand your content
  • Enables rich snippets (ratings, FAQs, breadcrumbs, events)
  • Use Schema.org vocab with tools like Google’s Rich Results Test

Plugins for WordPress: Rank Math, Yoast SEO

7. Fix Broken Links and Errors

  • Run regular audits to find:
    • 404 errors
    • Redirect chains
    • Broken internal/external links

Tools: Ahrefs, Screaming Frog, Sitebulb

8. XML Sitemap

  • Submit your sitemap to Google Search Console and Bing Webmaster Tools
  • Keep it updated — dynamic sitemap generators help with large websites
  • Ensure only indexable, high-quality pages are included
