A domain with www and without www will be recognized as a different URL by search engines. In addition, most people will type in the blog URL without the www automatically on their browser, it’s a habit, right?. If you don’t set it up, then when the visitors opened your blog without www, they will see the “page not found”.
To redirect from the non-www domain to the www a Ghost blog, you can use Apache. You can redirect it permanently.
I’m using Ubuntu and here is my config.
I created two VirtualHost in sites-avaiable directory.
Redirect permanent / http://www.tfq.me/
And for www domain:
The URL in config.js for Ghost is using www.
Don’t forget to reload your Apache service.
I’m using port 8080 because I also running Varnish and my Ghost blog is running on port 2370 because the default port is used for another Ghost blog.
