PR sculpting is an attempt by the webmaster to ‘funnel’ Page Rank into important places on a web site. Google gives each web site a certain ‘amount’ of Page Rank based on a number of factors but primarily weighted on how many incoming web links you have (relevant important web site send more PR versus irrelevant weak web sites). The idea was you could send PR to important pages over less important ones (like a privacy page) and then reap the benefits off increased rankings.
Well the age of PR sculpting is probably over. I say probably because on one hand sculpting with the ‘nofollow’ tag on links (ex. <a href=”https://www.examples.com” rel=”nofollow”/>) doesn’t work. On the other hand, you CAN impact how Google flows through your web site and indirectly benefit important pages. Here how.
Think of this example: all the PR sent to your web site is collected in a bucked (your web site) and each link (outgoing or internal) is a hole in the bucked. You CAN impact how Google will send PR to other pages by limiting how many internal / outgoing links you have. Google essentially looks at all outgoing links on the website and then calculates how man PR your own web site will flow to your other pages. If you reduce the amount of links you can increase the amount of PR.
That means this: in order to maximize PR and increase the stature of important pages you have to ensure your internal navigation is clear, concise, and concrete for the user. Try to figure out ways to improve user experience while simultaneously reducing the amount of links you have on a page (such as your homepage). It will do wonders to help make your web site more ‘efficient’ in passing PR internally.
