Technical SEO refers to the optimization of a website’s infrastructure to help search engines crawl, index, and render it more effectively. It involves improving aspects such as site speed, mobile-friendliness, secure connections (HTTPS), structured data, XML sitemaps, and fixing crawl errors. Unlike on-page SEO, which focuses on content, technical SEO addresses the backend and structural elements that impact a site’s visibility in search results. Proper technical SEO ensures that search engines can access and understand your website, which is essential for achieving higher rankings and better user experience.
