A ‘deep link’ is defined as any URL that directs a user to a page other than a website’s main homepage. This type of link is fundamental to an effective backlinking strategy and maintaining a balanced ‘deep link ratio’.
Deep links that point to a non-homepage resource are beneficial for ensuring a well-rounded backlinking strategy. The term ‘deep link ratio’ examines the count of all incoming links to a site in comparison to the specific number of incoming links directed only to its homepage.
The deep link ratio is frequently mentioned in discussions about whether a homepage is attracting an excessive volume of inbound links. There is no conclusive evidence that a site’s deep link ratio directly impacts its ranking, but it remains a logical factor for consideration. Therefore, it may often be more sensible to link directly to a sign-up form or a customer service page instead of the homepage.
It is also important to note that a different category of deep linking exists that, while popular in digital marketing and sales, is not directly relevant to search engine ranking. This second type of deep link can also refer to a web address that directs users to a specific location within a mobile application.
