What Is Technical SEO?

Technical SEO refers to optimizing your website’s backend structure to help search engines crawl, index, and rank your pages efficiently. It’s not about keywords — it’s about performance, architecture, and accessibility.

For beginners, understanding these technical aspects is crucial — because no matter how good your content is, Google won’t rank what it can’t access or trust.
