Bloggers have used a new technique to restrict users to publishing bloggers using an external FTP server, When the user from the internal blogger (blogspot.com domain name) to switch to their external FTP server, the blogger no longer directly using the 301 redirect function, but display a prompt box, let users confirm whether to jump the page, and the language of the prompt box similar to Google search in the malicious website hint, so that the unknown original Because the user dare not click to confirm, this causes the user to switch from the blogger to own FTP server, will lose nearly all search engine traffic and the original external link flow.
Google does want to promote its own blogger custom domain functions, but there is no denying that the blogger's custom domain does have a lot of functional flaws, such as weak user control, can not modify the htaccess file, can not use FTP file download backup, Can not even upload files ftp, especially for Chinese users, the blogger custom domain service IP address in China in the long-term blockade, most of the time is not normal access, which is enough to make Chinese users have to use their own FTP server to publish bloggers, This is a very helpless choice.
And now, from the Blogspot domain name switch to its own FTP will be limited by Google, which will lead to the loss of most of the original blog traffic, in order to maintain the original flow, users have to abandon their FTP and use the Blogger's custom field, so that Most of the user's services are under Google's control. From my personal understanding, it is dangerous to put all the eggs in one basket, and it is necessary for users to share the risk through some of the services they control.
For the existing blogger users, I suggest that they switch to their own domain name, whether it is a blogger custom domain or external FTP, do not rely too much on blogspot, because the use of domain name to switch, just switch domain name IP address, will not appear above jump confirmation, Thus avoiding the loss of flow.
