I'm having trouble understanding the strategy to increase PR through backlinks. This confusion is a mind swirling for me and I can't get the solution. When I go out and attain links to the blogs, should all the backlinks be pointing to the home page? Since in a blog, there are various different keywords throughout (as opposed to concentrated on one page or another like a normal site) what is the best strategy on "where" to point backlinks to?I've been doing a lot of research and can't seem to get a clear answer. Hope you can help me clearing up the confusion.
