What Is Technical SEO?
Technical SEO is the process of optimizing the technical foundation of a website so search engines can efficiently crawl, render, understand and index its pages.
While on-page SEO focuses primarily on content and keywords, technical SEO focuses on the systems and infrastructure that allow search engines and users to access your website.
A technically healthy website makes it easier for search engines to discover important URLs, process their content and understand how different pages relate to one another.
