Ive set up my first campaign selling stuff for amazon, ive got most of the details sorted and im pretty certain i can monitor and split test to get some decent results.

I have a question to any one who might know the answer. When using 7search, as you create your campaign you get the choice for destination URL and Display URL both of which ive left as my website address. But as you progress onwards and have the opportunity to manage each keyword individually, theres an selection that say "Custom URL" Does this custom URL change the Display URL entered as you start to create a campaign? I just dont want a massive affiliate link going to a different page than the first landing page?

Thanks in advance.
