Technical SEO refers to the optimization of a website's technical elements to improve its search engine visibility and performance. While on-page SEO and off-page SEO focus on content and external factors, respectively, technical SEO deals with the backend aspects of a website that impact its crawlability, indexation, and overall user experience.
