WordPress domain mapping FAQ

Q: How to I map my wordpress.com blog to a subdirectory of my current domain such as http://domain.com/blog ?
A: I’m sorry, but subdirectory mapping is not available. You could map to a subdomain as described below.

Q: I own domain.com, and want to map a subdomain of that to my WordPress.com blog. Is that possible?
A: Yes. You will need to add a DNS CNAME at your DNS provider before the domain mapping will work. You should not change your nameserver information if you just want to map a subdomain. The CNAME should look something like the following:

subdomain.domain.com. IN CNAME [your-blog].wordpress.com.

Once that DNS entry has been added login to your WordPress.com Dashboard, click on Options > Domains and enter subdomain.domain.com into the box. If everything is setup correctly, it will allow you to map the subdomain to your blog. If things are not quite right the system will let you know and provide suggestions on what you need to do to remedy the problem.

Note: You cannot map only the “www” subdomain since we remove the www from all the URLs at wordpress.com.
