Hey guys even i have the same problem, i sent a re-consideration to google and waiting to see what exactly happened! Hope to get a positive reply soon
you must have lost backlinks of your site, or you dont have quality contents and not frequently updated
Thanks for responding...but i have not made anything wrong that Google will penalize me. My site is proper and my backlinks are as before but i can't understand why Google penalize me and decreased PR.
I would almost think it's normal.. i had my site go up to PR2 few months back, then last January to PRZERO... nothing really changed drastically.. I'm aware of outgoing links and i keep it to a very minimal level. like 3 on my homepage, and nothing else.. still, i got back to NO PAGE RANK again.
If you have double-checked that your links are okay then give it some time and see what happens. It might as well go back to normal.
