hi,I have been running a small mobile site on a free host for one year which gets good traffic,three months back i got my self a new domain and directed it two my site.Recently i got surprise of my life when i checked its pr which turns out to be 6.I cross checked it many times and on many different sites but same result.I am at loss to understand how it got such a high pr in such a short time and that too without any seo from my end.Any comments?
