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.Guidelines

- Each page should use well-formed HTML or XHTML.
For more information, see WEB1042 - The page is not well-formed.

tag.

tag.

tag for each<script>
