Link lists are link collections of thematically different links. They are special websites on which links to other websites or domains are entered.
Such link lists are also called link farms and collect as many links as possible, which can usually be set by the website operators free of charge as Free For All ( FFA). The aim of these link collections is to help other websites achieve high link popularity through intensive linking and also to improve one's own web presence through high link popularity.
The entry in link lists can be detrimental for the website owner, because the search engines classify this linking as Bad Neighborhood. They do not evaluate websites with link lists or evaluate them negatively because they do not contain any relevant content anyway and downgrade them in their ranking, especially since an entry in link lists can also violate the guidelines of the search engine operators.
