rel="index" attribute in an HTML
<link> element is used to indicate the main index page of a website. It helps search engines like Google to understand the structure of a website and determine the most relevant page to show for a search query. Adding
rel="index" to the
<link> element of the main index page of a website can help improve its search engine optimization (SEO). However, this attribute is not widely used and is not essential for SEO.
rel="index" link attribute is used in HTML to specify the primary document representing a group of documents or sections on a website. Search engines use this information to determine the most important page within a group of pages, and it helps to establish a hierarchy of information. This attribute is typically added to the
<head> section of a web page and can be used in conjunction with other link attributes, such as
rel="prev", to indicate the relationship between different sections or pages of a website.
