I have a 1 month old domain, it was PR N/A last time, I checked my domain's pr yesterday, and there it showed PR4. Check it yourself: http://selenatoday.com
Hello, I think google has updated the PR as well as Back ward link. As few of my sites gained the PR and few lost same with Back links also happened on 9 September 2010
Well,i have checked your site, and believe me i have never seen such a miracle. How could a one month site manages for have 2,124 yahoo indexed backlinks. And how you can have a PR of 4 just within a month. I would like to know how you have marketed your site....
I never really thought that it would be like that after 1 month, that is why I am so thankful after my host (my host bought and hosted my other domain) took my previous site where he changed all the passwords to wordpress, coppermine, webmain, and cpanel. There were no 301 redirections. Mainly it was twitter and facebook probably that made it like that. My site still receives around 600 unique hits a day, and my twitter account has over 1.2k followers. So sorry, I don't know what to answer to your question as I was as amazed as you are. Thank you so much sir.
