[h=2]Setting Up a Subdomain for Blogger[/h]Create your subdomain using your domain registrar or Web hosting company, and change the CNAME for your subdomain to "ghs.google.com." If you're unsure how, check your registrar's help documents; Google also offers tutorials for several hosting companies in Blogger Help.
Once the subdomain is set up, go to "Settings," then click "Publishing" to view your domain options. View your domain setting options by clicking the "Custom Domain" option beside Switch To. Blogger initially offers you the option to purchase a domain; click the "Switch to Advanced Settings" link to use your own domain. Fill in your Blogger URL. For example, it might look like "blog.yourdomain.com". Fill in the word verification, if asked for, and click "Save Settings." If you want to redirect yourdomain.com to your chosen URL, select that option and save your settings again. It can take up to 48 hours for domain changes to kick in.
