Technical SEO: What it is & How it Works

What's covered:

Technical SEO is a critical component of search engine optimization that focuses on improving the technical aspects of a website to increase the ranking of its pages in the search engines. This article explores what technical SEO is, how it functions, how it differs from on-page SEO, and provides a guide on implementing technical SEO effectively.

What is Technical SEO?

Technical SEO refers to the process of optimizing a website’s infrastructure so that search engines can crawl and index it effectively without any problems.

It includes a range of activities from improving the site’s architecture, implementing secure connections (HTTPS), enhancing mobile-friendliness, to speeding up page load times.

Technical SEO ensures that a website meets the technical requirements of modern search engines with the goal of improved organic rankings.

How Does Technical SEO Work?

Technical SEO works by making sure that a website is not only functional, but also compatible with search engine crawlers. This ensures that the website can be indexed in SERPs.

It involves optimizing the site architecture, improving site speed, ensuring mobile responsiveness, and securing the site with HTTPS.

These adjustments help search engines understand and rank the site more effectively while also enhancing the user experience.

On-Page SEO vs Technical SEO

While on-page SEO focuses on content elements on a website, technical SEO deals with the technical aspects that help improve the structure of the site.

On-page SEO aims to make web pages more relevant to user queries with optimized keywords, headers, meta tags, and images.

Conversely, technical SEO ensures that the site as a whole is structured and coded in a way that search engine spiders can crawl and index it efficiently.

How to Do Technical SEO

Here are some common guidelines for implementing technical SEO practices into a website:

  • Improve Site Speed: Use tools like Google PageSpeed Insights to find and fix issues that slow down your site. Minimizing HTTP requests, optimizing images, and enabling compression are effective strategies.
  • Ensure Mobile Responsiveness: Make sure your website is responsive and provides a good user experience on mobile devices. Google’s Mobile-Friendly Test can help you identify areas for improvement.
  • Secure Your Site with HTTPS: Migrating your site to HTTPS secures the connection between your website and its users, which is a factor Google uses for ranking.
  • Optimize Site Architecture: Ensure your website has a logical structure that makes it easy for search engines to crawl. This includes a well-organized internal link structure, a sitemap, and a robot.txt file that tells search engines what to crawl.
  • Fix Duplicate Content Issues: Use canonical tags to point search engines to the original version of the content, helping prevent problems caused by duplicate content.
  • Implement Structured Data: Use schema markup to help search engines understand the content on your pages more effectively, which can improve the way your pages are represented in SERPs.
  • Monitor Crawl Errors: Regularly check Google Search Console to identify and fix any crawl errors that could prevent your pages from being indexed.


Technical SEO not only helps in making your site accessible and indexable but also provides a better experience for visitors, increasing the likelihood of conversions and return visits. Regular audits and updates to the technical side of your site are crucial in maintaining an edge in the highly competitive digital marketplace.
