Technical SEO is the foundation that helps search engines discover, understand, and confidently rank a website. When pages load slowly, essential content is inaccessible to crawlers, or the site architecture creates confusion, even excellent content can struggle to reach the right audience. This practical course gives you a structured way to diagnose and improve the technical factors that influence organic visibility and user experience. You will learn how search engines crawl and index websites, how to evaluate robots.txt and XML sitemaps, and how to identify common indexing problems using a systematic audit process. The course then moves into site architecture, internal linking, canonicalization, structured data, mobile readiness, and JavaScript SEO. You will also understand the three Core Web Vitals metrics, how to interpret field and laboratory data, and how to prioritize performance improvements that affect real users. Designed for developers, technical marketers, SEO specialists, content teams, and website owners, this course is suitable for learners who understand basic websites but want a more reliable technical SEO workflow. You do not need to be an advanced programmer, but familiarity with HTML, web hosting, and browser developer tools will help you apply the lessons more effectively. By the end, you will be able to perform a focused technical SEO audit, connect technical findings to search visibility and user experience, and create a prioritized optimization plan.
