A deep link is a hyperlink pointing to content on a particular web page, instead of the home page of a website. Deep linking is the practice of using this type of hyperlinks.
Deep linking can have an effect on the authority of a page, in addition to increasing domain authority. This can be used for SEO purposes.
What is deep linking?
Deep linking refers to the practice of setting up particular web pages, instead of the home pages, as the target of one or more hyperlinks. Technically, there is no difference between these two types of hyperlinking. However, deep linking is more practical for users, pointing them directly to the source of a piece of information. Otherwise, they would be forced to take the extra step of searching for that particular piece of content on the entire target website. Furthermore, deep linking can be important for SEO purposes, as it increases the authority of any page, in addition to having an effect on domain authority. Internal linking on a website (linking web pages from the same domain) is also a form of deep linking.
Deep linking issues - is there a problem with deeplinks?
From a legal perspective, there have been claims against deep linking in the past. These came from websites who were unhappy with the fact that their homepage was circumvented by deep linking. However, it has been ruled that there is no problem with deep linking and it is allowed, as URLs are addresses in the public domain. Website owners always have the option to restrict access to any webpages they want. Websites with subscription-based premium content may use this type of system, in which case accessing a hyperlink to a restricted page will lead to a 403 - Forbidden error if the user does not have the proper credentials.
