i have a selfhosted blogger blog techbreez.com .I want to transfer to wordpress. will it affects my page rank 3.
If it is your domain then no but if you are going from a free blogger domain to free wordpress then yes it will affect it.
this blog is about latest technology.I have bought it and its now got pagerank of 3.If i shift to wordpress, then no change to my blog or indexing.
If you are already using the domain name, then all you have to do is change the nameservers to point to your self-hosted WordPress install. No PR loss should occur.
