How do I pass the keywords through the subid, that various cpa networks like azoogle provide? so that I can see which keywords converted?
use {keyword} ex: affilate.com/track.php?id=123456&subid={keyword} google will replace {keyword} with the actual keyword that was searched.
If your direct linking then would would set your ad url to this: www.affiliatelink.com/offernumbers&subid={keyword} and google will place your keyword in the subid. However if your going to a lp you would set your ad url to this: www.mydomain.com/page.php?kw={keyword} or mydomain.com?kw={keyword}, then on your LP you would make your AFFILIATE link look like this: www.affiliatelink.com/offernumber&subid=<? echo $_GET['kw'] ?> what that does it is "grabs" the "kw" from the adwords ad url and places it into your affiliate link subid. So in your adwords url if someone came to your site under: mydomain.com?kw=flowers, then the <? echo $_GET['kw'] ?> in your affiliate link would pull the kw flowers, and place it into the subid spot, so it would be afflink.com/offer&subid=flowers
If you need more help on it there is a video that explains it all too, it is kinda long but it shows how subids work and some examples. http://tracking202.com/blog/subid-tracking-explained-how-subid-tracking-works
keywords have no meaning in content, you do not want to pass {keyword} for content since google is not mapping the ad to a keyword.
