1. one link from a PR 4 from a blog where the content is about oil, usa, friends and so on .. (amalgam that is) 2. another link from PR 4 from a site related with morgage. Both links are pointing to a mortgage site. How much will the first link influence the PR of the site and how much the second ? What is the big difference....? Thanks.
the context doesn't influence the pr.. both help your pr the same (if they have the same number of outgoing links) context links are good for SERPs rank
