I have a main domain which has a pagerank of 6. And also has a sub-domain. I gave a link to sub-domain from main domain to pass the pagerank. But the pagerank is not passed to sub-domain from the main domain. At present, my sub-domain pagerank is 0. How to increase my sub-domain pagerank? Please Help. Thanks in advance.
In order to increase PR of any page, domain or sub-domain, you need to get lots of backlinks. Try to get some backlinks from high PR pages.
yeah... it's not really important if it's a subdomain or any other page - make sure you link to it from high PR sites
if you want your sub pages have a PR, try deep-linking... uhhm, I know it is for Directory submissions... make use of all you sub pages so that you'll gain more traffic.
Do offpage activity forum posting, guest posting, blog, blog commenting, press release for your sub-domain...
