How to Remove Blogspot from a URL
Blogger is a free publishing website for blogs with customizable templates. The site hosts the blogs on Blogspot.com. However, the blogs are considered subdomains and consequently have URLs that contain "blogspot," such as www.examplesite.blogspot.com. It is possible to change the URL to one that does not display the hosting site. You can do this by obtaining a new domain name independently or through Blogger.
Purchase a Domain Name through Blogger
Sign in to your blog account, and click the "Design" link in the upper right corner of the page. Click the "Settings" tab, and click the "Publishing" link.
Click the "Custom Domain" link to proceed to the "Publish on a custom domain" page.
Type the address you want for your blog in the blank field, and select an extension from the drop-down list.
Click the "Check availability" button. If the domain name is available, click the "Continue to registration" button to proceed. Pay the $10 registration fee with a credit or debit card. Note that it may take up to three days before the new domain is effective.
Use an Existing Domain Name
Purchase a domain name from a domain services provider, such as Godaddy, 1&1 or Hover (see Resources). Proceed to the "Publish on a custom domain" page in your blogger account.
Click the "Switch to advanced settings" link. Enter your domain name in the blank field.
Type the letters provided for verification in the "Word verification" field. Click the "Save settings" button to complete the process.
