Page and site guidelines for SEO
Each page in your site should follow coding best practices.
Explanation
Each page in your site should follow coding guidelines to help make sure that search engines can accurately analyze your site. If a page is not well-formed, or if it lacks specific tags, such as the <body> or <html> tags, search engines may not be able to find relevant text in the page. This would reduce the page ranking in search-engine results.
