    One question Brad – if you have 4 ads (2 all and 2 mobile preferred) will the all ads show on mobile? I wish they had a separate desktop and tablet preferred option.

    Technically, they shouldn’t.

    However, I do see some cross over (it’s a small percentage where your mobile preferred ads show occasionally on a desktop and vice versa. I really hope this gets fixed as it really causes destination URL issues when you are using a mobile only and a desktop only landing page.

    exactly, that could skew results significantly. also we’ve used mobile specific ad copy that has helped us tremendously which wouldn’t apply to desktop and using a normal desktop ad for mobile takes away our differentiation.
