number of outgoing links;
total amount of links;
the presence of a back link;
TIC and PR;
Link weight is one of the important ranking factors in every search engine. The exact algorithm for calculating the link weight is very complicated and not completely known, but any optimizer needs to know the main principle of weight transfer.
