It's really important and difficult question.
It not depend on the script you are using (ANS or not), it more depend on the Ads which you will create.
Good results will be if you will have target keyword in the Title of your ad,
in the description.
Also same keyword should be on the site: in the TITLE tag of the landing page, in the Description tag,
in the Text on this page, in the URL of the page.
So the more Ads you will create the better. (separate Ad and separate landing page for each theme).
For example if you want to promote
Camcorders, you should choose as a landing page
this page:
http://demo.affiliatenichescript.com/El ... amcorders/It have keyword
"Camcorders" in the URL, Title, Description, Texts.
On this page is listed only Camcorders. Google will see all these things.
And your Ad you should create like:
------------
Title: Buy Best
CamcordersDescription: List of the world's best
Camcorders from the top shop.
------------
So if you will do all these things - google will give you good Quality Score...
