My PR dropped to 0 from 2

don't worry about page rank, worry about traffic and converting.
IMHO a pr 2 might as well be a 0, both are very very low on the totem poll and easy to achive

 

i disagree with someone who says that PR is not important, PR is the most important to get job from advertiser, backlink can be develop with link exchange....actually i don't understand how to determine PR drop or increase.....there is no absolute formula...

 

Your statement is a little at odds with your signature ...

 

Nope. I do not use spam submitted links.

 

lol, That is about backlinks.

Don't worry, if you haven't done anything wrong then it would be back soon and probably increased something to PR3+

 

i am agree with you. You are absolutely right.

 

be patient and always keep spirit
