Would you have thought that the speed of your website could even affect your revenue?

Technical SEO (tech SEO) addresses precisely these issues—it helps ensure that your website is not only visually appealing, but also fast, secure, and search engine friendly.

In this article, we will explain what technical SEO is, why it is so important, and how we work with it at HiData.

What is technical SEO?

Technical SEO refers to the optimization of website elements that enable search engines, such as Google, to easily crawl, index, and interpret the content of the site.

The goal of technical SEO is to:

  • the website works quickly and without errors,
  • search engines can freely access all parts of the site,
  • the content should be well structured and understandable.

 

The three pillars of technical SEO

Pillar Goal Effect
Performance Speed, safety, responsiveness Faster site, better UX
Mappability Improving search engine robot routes Better indexing
Structure and data Organizing and interpreting data Better visibility and rich results

 

The importance of technical SEO

Google maps billions of pages every day, but only indexes and ranks those that are technically sound.

If a page is slow, buggy, or not mobile-friendly, the search engine will simply rank it lower.

Why is this important to you?

  • 531% of users leave a website if it takes longer than 3 seconds to load (Source: Google Think, 2024).
  • Core Web Vitals values—such as LCP, FID, and CLS—directly affect rankings.
  • Broken links and slow pages not only hurt SEO, but also hurt business results.

Why is Tech SEO important?

  • Without technical SEO, there can be no sustainable online growth.
  • A fast, error-free website is a basic requirement for good ranking.
  • Google „loves” well-structured, technically clean websites.

 

The relationship between technical SEO and other areas of SEO

Technical SEO is the foundation upon which on-page SEO and off-page SEO are built.

It doesn't matter if you have good content or a strong backlink profile if the search engine can't crawl your site due to technical errors.

Balance on three levels:

  • Technical SEO → functionality, indexability
  • On-page SEO → content and keywords
  • Off-page SEO → credibility and link profile

 

If any one of these is missing, the other two cannot function properly.

 

The benefits of technical SEO

According to recent research, Google may rank fast pages two positions higher than their slow competitors. We have compiled a list of how certain elements of tech SEO can help your website.

  • Faster website → lower return rate
  • Better user experience (UX) → more time on the website
  • Higher ranking → more organic traffic
  • More stable technical background → fewer opportunities for error

 

Why is technical SEO so important?

Google robots (also known as crawlers) constantly scan the internet and collect data from websites.
If your website is difficult to crawl, robots may simply skip some of your subpages from the index.

Technical SEO helps:

  • full accessibility of the website,
  • minimizing errors,
  • and in getting the content into Google's index as quickly as possible.

 

User experience and tech SEO

User experience (UX) is now a key ranking factor. A well-optimized technical site can improve organic conversion rates by as much as 25–30%. (Source: The Pitch, 2024)

Technical SEO ensures that:

  • the website should be responsive,
  • images are displayed in an optimized manner,
  • there should be no disruptive errors or delays.

 

Examples of the impact of technical SEO

What effects can technical SEO have on your website? To help you understand what to look out for, we have provided some examples of common problems that professional tech SEO can solve.

  • Slow page loading → high return rate
  • Not mobile-friendly site → lower ranking
  • Incorrect redirects → indexing errors

What else?

  • Google is UX and technical quality combination.
  • Everything SEO campaign begins with a technical audit.
