Have you ever noticed that the pr ranking changes if you add or subtract the www. before the url?
For example
http://www.trenchcoatyuppies.com/pages/790488/index.htm =pr3 but if you remove the www and just put
http://trenchcoatyuppies.com/pages/790488/index.htm it has pr0 ?
Another example is
http://onlinemusicpromotion.com has a pr0 but when you
add
http://www.onlinemusicpromotion.com it is pr3
Does anyone know why this is?
