This is about Google and not about site. I am taking site as example. I am doing seo of http://www.marinews.com PR: Zero Cached: Not Serps: #1 on fishing knots When I search for fishing knots http://www.google.com/search?source...rls=GGLG,GGLG:2005-47,GGLG:en&q=fishing+knots I found my site at #1. When I see the cached from SERPs http://72.14.203.104/search?q=cache...s.com/fishing_welcome.php+fishing+knots&hl=en I found it cached on 17 Jan. When I see the current page http://www.marinews.com/fishing_welcome.php and than cache of this page from google toolbar, I found it is NOT cached. Why is it so? Seeing from one way page is cached and seeing from other way it is not cached. why? What google is doing?
I found it for many pages. What happened is: Earlier I was having domain with www like http://www.marinews.com Than I have changed it to http://marinews.com for some technical requirement. Since domain without www have PR0 and It was a danger that PR of domain with www will lost. I again changed it back to www version. The pr is lost.. But I don't know weather my pages are indexed or unindexed ??? But I am happy that I have not lost any of my ranking in SERPs. I don't know what Google is doing???
