I've been using
ThriveTracker is 100% prepped for the use you've described above.
We're less expensive when scaling for pop and native numbers (we don't charge per event like they do).
We operate solely on user-owned custom domains, so your domain authority is always yours.
And we have a no-link, pixel-based tracking method that will allow you to direct link to your landing page URLs and still gather the same great insight data. You can read more about that feature and its abilities in the blog post from the release: http://blog.Thrivetracker.com/the-0m...racking-pixel/
Come try us for 30 days at no cost, track for less money each month, and track all your traffic (including GDN) without worry.
And if you'd rather save a little more money, I've got an offer for STM customers to take advantage of as well 
Cheers,
