Whatever you do, do NOT redirect users from every single page on your site to the same mobile site homepage. That breaks ALL of your incoming links to e.g. articles on your page, which is incredibly frustrating. If you’re going to redirect to a mobile site, make sure you redirect to the mobile equivalent of the page the user landed on in the first place – not just the homepage.
