Technical SEO – Complete Guide to Website Optimization

Technical SEO encompasses all optimization activities performed within a website that help search engine robots better understand and index the site. Its goal is to improve site structure, loading speed, security, and functionality. The main aspects of technical SEO include:

• Indexing and crawlability
• Page loading speed (Core Web Vitals)
• Proper URL structure and internal linking
• Security and HTTPS implementation
• Structured data implementation (Schema.org)

If you neglect the technical aspects of SEO, Google may not be able to properly process and understand your website content, which will automatically worsen your SERP results.

Key Elements of Technical SEO

Below are the most important actions to take as part of technical SEO:

a) Creating a Sitemap (XML Sitemap)

A sitemap is an XML file that tells search engines which pages on your site are most important and how often they’re updated. How to implement a sitemap?

• Generate an XML file using tools like Yoast SEO, Screaming Frog, or your CMS
• Add the sitemap to Google Search Console in the “Sitemaps” section
• Ensure all important pages are included and unimportant ones are excluded

The sitemap eliminates the problem of orphaned pages that have no internal links leading to them. Thanks to it, search engine robots will reach every important subpage of your site.

b) robots.txt File

The robots.txt file allows you to control which parts of your site should be indexed by search engines. This way you can save valuable crawl budget. Best practices:

• Block technical pages like shopping carts or internal search results (e.g., /search/)
• Place the robots.txt file in the root directory (e.g., domain.com/robots.txt) and configure it correctly
• Check the file’s correctness through Google Search Console
