Definition
Technical SEO refers to the optimization of a website's technical infrastructure to help search engines crawl, index, and understand the site more effectively. It focuses on the behind-the-scenes elements that impact search engine performance, including site speed, mobile-friendliness, crawlability, indexability, site architecture, and server configurations. Unlike content-focused SEO, technical SEO deals with the foundation and framework that enables search engines to access and interpret your website efficiently. This includes optimizing server response times, implementing proper URL structures, ensuring mobile responsiveness, and creating clean, semantic code that search engines can easily parse.
