I was going through a post by Matt Cutts on PageRank Sculpting. And it really explains a few basic things on PageRank mechanism from Google’s point of view. It undermines the importance of PageRank Sculpting. If you don’t know what PageRank Sculpting is, then for a primary knowledge I can say that it is a way of controlling link juice flow within your site by making certain link portion nofollow artifially. For example, consider making “Archives” & “Category” part of your WordPress blog nofollow. Here are a few quick things that you should know from that post:
- Nofollow link doesn’t pass PageRank juice at all. You can be sure of that.
- Now I am giving an example from that post about the link juice flow. Suppose you have 10 PageRank points on a page. The page contains 10 outbound links & 5 of them are nofollow. And there is no decay of link juice while passing. So you will think, 5 dofollow links will get 2 points each. But that is not the case. Rather 5 dofollow links will get 1 point each.
As you can see, even though nofollow links doesn’t pass PR, it consumes the PR points. So even if you mark certain links nofollow, you are loosing points depending on the number of nofollow links. So there is not much of value in doing PageRank Sculpting. That’s what you need to know as a new one in the webmaster field.
By the way, if you have some sort of knowledge & want to explore the post if you haven’t already, here is the link to the blog post.
