I would like someone to point me in the right direction. I want to have a sub-folder in the website that shows the same posts and same content as the regular blog (using the same database), but with a different simplified theme.
For example, it would be http://www.example.com and http://www.example.com/mobile/. The mobile users would see a simplified version of the site in the mobile folder. When they click on the links, they stay in the mobile folder. I am going to disallow robots from the mobile folder to avoid any duplicate content penalties in Google.
After reading a lot of information about multisite, I think it might not be the best approach. If I understand it correctly, the multisite is used for different blogs with different databases. Should I use a child theme on the sub-folder instead of setting up a multisite? What is the best way to do this? I can edit PHP code if I need to. Thanks.
