recently i have noticed Google has updated PR for every website and my website home page was holding PR 2 before and inner pages were not given any rank , recent changes made me shock where one of my inner page was given PR 3 but still my home page remains PR 2. and i was wondered how this was happened . i never do much off page techniques to inner page rather then the home page. can any one clarify why this happened ?? and is it good sign to have better PR for inner pages then the Home page..
