What Are the Types of Technical SEO?

Technical SEO breaks into several connected areas. Crawlability covers making sure search engines can reach your pages, through clean site structure, internal linking, XML sitemaps, and a correct robots file. Indexability covers whether Google stores your pages, handled through canonical tags, correct index directives, and removing duplicate content. Site performance covers speed and Core Web Vitals, including load times and mobile responsiveness. Structured data, or schema markup, helps Google understand your content and can earn rich results. Security and site health cover HTTPS, broken links, and redirect chains. These areas overlap, and a problem in one often shows up as a symptom in another, which is why I audit them together rather than in isolation.
