I am seeing that site wide navigation has been reduced in value completely and that the page rank of internally linked pages has been reduced dramatically. For example: My home page and 30 main topics linked from it all used to be PageRank 5. Now the home page is page rank 5 and all of the sub pages vary from PR0 to PR5 for some of the pages that have external deep linking to them. Is anyone else noticing this? Any thoughts? Is there anyone who has homepage down navigation noticing the same thing or is it site wide navigation that has been devalued? Appreciate your thoughts and observations.
