In case you want to test a lander page keep in mind that
adwords considers also ad ctr and lander quality score
and that can be a reason for you not getting any clicks
or very expensive ones.
Tell me more about this. I have heard something like this before, but it didn't make sense to me for two reasons.
1) Until recently, traffic estimator worked, even if you
were not logged in, which, seemed to negate the idea of
them using site quality in their analysis.
2) Even when logged in, I don't ever actually link my ad-words account to any
specific site, and using traffic estimator or keyword
tool, I'm never given the opportunity to tell them which
site I'm buying ads for, or even which campaign I'm buying
ads for. I have multiple campaigns set up for different
sites. How would it know which campaign/site I'm
researching keywords for?
