Thanks...

and My PR is SAME before~~

 

Search your keywords on Google and see if you rank for them as normal, if your not then you most likely got penalized

 

I heard if site penalized, index ratio gets worse.. BUT, my site index ratio get better ..

 

Well then, if your sure you didn't penalised you most likely drop down heavy on the SERPs for one reason or another. Hence not reaching the same amount of visitors..

It could mean you've slacked on your SEO work or your competitors have uped the anti ~ do a search like I recommended and see if you still rank.

 

thankx... So.... It's hard for my site to get back traffic from google?
How can I do that~~?~~~ PANIC~~ CRY~~ HELP ME~~

 

you should always maintain the list of keywords for which you were ranking - by that way you might know where or what went wrong .
