I have a question for you guys. I changed my domain name but i didnt do the permanent redirect 301 through my host. After couple weeks i checked my old domain and the page rank had changed. i checked the new one it was still the same. Then i did redirect 301 of the old site to the new one. I heard that google will make the changes in a week or two. Now it has been 1 month it hasnt changed anything. how do i contact google about this ?? do they actually answer to these types of problems?
May be when you change your domain, Google bot visit your old domain and update your PR (minor update). You can request reconsideration to get your PR back, but it usually google not answer your question.
