Head Tag (in HTML)
The head tag is an element in HTML files which can contain metadata (data about data) and script calls. The head tag is placed between the opening
tags at the beginning of the HTML file. The metadata in the head tag is not displayed, but the information is used by browsers and by search engines. The most important tags appearing in the head from an SEO perspective define the page's title, description, styles, robot instructions such as noindex and nofollow and social media sharing information.
