Link popularity is a term for the number of external backlinks that are found for a domain, regardless of their source.
What is link popularity?
Link popularity refers to the quantity of incoming links on a domain. This metric is not a reflection on whether the links came from one domain or several.
Link popularity is thus another metric, in addition to domain, network and IP popularity, that is used to evaluate incoming links.
The evaluation of a website according to link popularity is based on the premise that websites which are frequently linked to represent added value for the user.
However, the problem with this way of thinking is that links can be bought in large quantities, so this number is no longer a reliable indicator of quality.
Nowadays, it is generally the case that the quality of the page that provides the link is much more important than the number of links.
