Hello did some research this past weekend. Here is what I have come up with: 1. build website using responsive wordpress theme, and website will be automatically mobile friendly. no plugins. 2. build website using regular wordpress theme. use a mobile plugin to redirect mobile users to a different version of site. 3. build website using responsive wordpress theme, AND use a mobile plugin. 4. ?? other options that I haven't found ?? Which choice is better? would using a plugin to redirect mobile users hurt seo? any plugins that you recommend?
