If you have existing sites that get traffic, you're crazy not to do something with the mobile traffic.
It can account for about 5% and up of your traffic, and if you're sending it to the right spot...it's more money in you're account at the end of the day.
It's a no brainer. If you want to mobilize your existing tours, hit me up and I can help get you moving in the right direction.
