What is Technical SEO?
Technical SEO is the process of optimizing your website’s technical structure so that search engines can crawl, index, and rank your pages more efficiently.

It includes website speed, indexing, security, structured data, mobile optimization, URL structure, crawlability, and many other technical improvements.

Without a strong technical foundation, even high-quality content may struggle to rank.
