For any business or website owner aiming for long-term value, enough value is in understanding what is and how technical SEO works and why it matters.
Having experience in advanced technical SEO, and SEO audit consultancy where I helped businesses, I understand how impactful small technical issues can be to your SEO rankings. This guide will take you from the basic technical SEO audit and will help you with advanced tips, tools, and strategies.
What Is Technical SEO?
Technical SEO is the part of SEO which optimizes the website’s hidden system. It helps the search engines crawl your site, references index, and ranks the content. Technical SEO does not work with content creation or audience engagement like on-page or off-page SEO. It is concerned with the site’s performance, security, and overall structure.
Improving the technical side of your website means laying a better foundation to help build your content and links. Some of the most important areas are:
- Website Crawlability and Indexation: Making sure your pages are reachable.
- Site Speed and Core Web Vitals: Improving the load time, LCP, CLS, and INP.
- Mobile Friendliness: Complying with Google’s mobile-first indexing.
- Security: Using HTTPS and secure protocols.
- Structured Data and Schema: Helping search engines get the context of your pages.
By addressing these factors, technical SEO issues like broken links, duplicate content, or slow pages are minimized, creating a strong foundation for higher rankings.
Google Search Console, Screaming Frog, and SEMrush are great tools to get a proper technical SEO audit.
Why Is Technical SEO Important?
Having a website with technical SEO means your pages are fast, secure, and easy to crawl. This all directly impacts search engine rankings, user experience, and the growth of organic traffic.
In 2025, search engines will prioritize not only the quality of content, but also the experience and performance of the website. Here is why technical SEO for WordPress and other platforms is important:
- Improved Search Engine Crawl Efficiency: Helps avoid missed pages and indexing issues.

Ignoring technical SEO tips can cause even the best content to underperform in search results.
