I recently found a offer which i was interested in on google adwords, i noticed there's about 3-4 sites which have the offer on their webpage which they promote via ppc. I signed up to the company who has the offer, and on their conditions page they clearly state NO SEARCH MARKETING. I emailed them telling them that there are sites on google adwords promoting the offer via ppc, they sent me back a generic reply. I was wondering how do they get away with this (lousy affiliate manager), and how could i promote this offer without them finding my traffic is coming from pay per click traffic?
