I moved my PR5 site to a new server and domain address. I put a 301 redirect to the old server pointing to the new address. At first everything seemed to go ok: Google Toolbar showed PR5 in the new address and all my backlinks were there. But after a few days the PR was dropped to zero. It has stayed there over 3 weeks now. I still see my old backlinks. Also, some of my subpages in the new domain still have the old page rank. I have not done anything too bad to get penalized. My new site is visible in the Google index but obviously it is not ranking well. I don't know about spidering because I haven't installed a log viewer yet.
Will I get my old page rank back and when will it happen?
