From what I have read in this forum, it's been pretty much established that SE results do not directly compete with adwords (that is, it's good to have high ranking and adwords -
some people will click on one, some on the other).
What I would like to know is whether there is a similar
distintion between people who click on sponsored listings
and those that click on adwords. In other words if I
managed to have my adword migrate "up-north" (see a post
in this forum on how to do that), am I losing a % of
potential customers who do click on adwords but not on
premium listing. Obviously, my ad can not be at 2 places at
the same time (premium listing and side bar), but this could
be circumvented by using different domain names (or would
Google frown on that?)
