The Sheets template in this module is based on Kevin Indig's "True Internal Page Rank" model for optimizing a site's internal linking structure.  

The gist of the TIPR model is to balance three internal ranks between your pages:

• Internal links in (pagerank)

• Internal links out (cheirank)

• External backlinks in

To evenly spread authority throughout your site, by adding new internal inlinks / outlinks where needed.
