...but since the panda update its going down and down.
Do you mean the FIRST panda update in February 2011? Or a subsequent update?
Since the last 2 weeks my site dropped its position in Google even with domain name.
How exactly are you searching for the domain name?
Are you using:
my domain name (assuming you have more than one word in the domain name).
Also, have you tried searching for a unique string of text on your home page? (try using both with quotes and without quotes around the unique string of text) Maybe people are scraping your site?
Also, as best as you can tell, when exactly did the drop happen? Can you look at your anaytics and see if there was a date when traffic took a dive?
i don't think there is a -4 penalty (maybe there is, who knows?). Hopefully someone with experience dealing with pandalized sites will chime in and let us know whether it is common for a Panda victim to lose rankings for its own domain name.
