LP quality scoring on the CN has become a much bigger factor than it has been in the past. If it's a remotely competitive niche, forget about it. IMO, you're much better off making your own killer LP. Note: one-page landers don't fly on the CN, so you need to be prepared to create an entire mini site (yes, it's a pain in the ass). Also, if it appears that the only purpose of your LP is to send visitors to another site via aff links, the first human reviewer will shit-can your campaign (if the bot/algo doesn't automatically off the bat). G wants the LP to have useful content that stands on its own, not just a bridge page. It's a delicate balance that can make you want to ship Google a big box of dog shit.
