I'm not sure I'm following you -- when you say landing page vs. web page do you mean web page as in a whole web site? Or do you mean the affililates landing page vs. a web page of your own?
I find landing pages seem to get higher search results and better click-thru's on my PPC's, if that helps any. Just focusing on the product you're selling, IMHO, is the way to go for a serious sales pitch.
Maybe if you could elaborate a little more as I'm a little confused as to just what you mean - -and it's probably me as I'm exhausted from moving and not absorbing things the way I should!
