While often used interchangeably, on-page SEO and technical SEO are not the same. Ultimately, on-page SEO covers your page's content, meta tags, images, and the like. Think of these as the page elements that are visible to users.Technical SEO, on the other hand, is all about how Google crawls and indexes your site. Think things like site speed, structured data, canonicalization, XML sitemaps, hreflang, and more.
