For example if I got a backlink from a webpage called lets say www .computers. com/cpuforum If the pagerank of the domain (www .computers. com) was lets say 5 but the page rank of the sub-domain (www .computers. com/cpuforum) is 0. Will search engines recognize my backlink as a pagerank 5 or 0? I already know that they are some complicated calculations for weighing backlinks in terms of boasting my serp (like the total amount of outgoing links on the page etc). I just want to know which one of the pageranks my backlink really has.
