I am using Site Scout right now and wondering, what would be the best way to split test multiple ads and landers?
Will Site Scout even allow a tracker like CPV Lab to rotate multiple ads and landers?
Not too sure about Site Scout, but rotating your landers happens in your tracker, not the ad server. I haven't used CPV Labs, but I've heard from others that it's pretty easy to rotate landers and offers. You need to get you campaign URL from your tracker and that's the link you use in the ad server for your ads, you'll also need to add tokens to the campaign URL to identify the different ads, some ad networks have dynamic tokens to add them automatically, but if not then you'll have to add them manually.
SiteScout won't allow you to rotate multiple landers, or at least they wouldn't the last time I used them. They may have changed their policy - I certainly hope so - but I haven't heard that they have.
If they haven't, it's a serious pain in the ass. IIRC, the best way around that is to create multiple identical ads, and link each ad to a different lander. That way you get a pseudo-split-test effect.
