My home page was ranking number 3 for a key word, about 4 days ago one of my inner pages replaced the home page. i.e
home page - pr 4 off page optimization (high). on page optimization medium
inner page - pr 0 off page optimization (none). on page optimization high
only logic I have on this matter is that Google conducted a Manuel review on my site and deemed the inner page to be more relevant (which it is), but the problem I have is, which page do I optimize home page or the inner page or do I just leave it as it is?
Before any one asks I have reset the browser settings etc and checked off 5 different p.c's. And my whole web site due to traffic and social marketing gets indexed daily.
