Drop in position

Just a few days back my site ranked at 1st place in msn for the terms "pertusis disease". Now it is nowhere to be seen. I made some changes to the site by including 17 new sub-domains. Can this be a reason? Should I remove the sub-domains? Also how do I change the site from http://xyzxyz.com to http://www.xyzxyz.com?
Thank you in advance for your advice.

MSN does this as they continue to tweak their algorithm. Couldn't hurt to try though as you have nothing to lose.

Also how do I change the site from http://xyzxyz.com to http://www.xyzxyz.com?

Hi,

Please check for the website's cache in MSN. i.e try to find info, when you type the entire URL in the MSN search box. Add as many one-way links, which will greatly help you in rankings :)

Let me know if you need one-way links :)
