Up until May 1, 2010, Blogger allowed users to publish blogs on other hosts, via FTP. All such blogs had (or still have) to be moved to Google's own servers, with domains other than blogspot.com allowed via custom URLs.[6] Unlike WordPress.com, Blogger allows its users to use their own domain free of charge, while WordPress.com charges around $13 to use a custom domain.[7] Blogger cannot be installed on a web server. One has to use DNS facilities to redirect a custom URL to a blogspot domain.[8]
