Hi,

Is there a simple way of performing split testing of different landing pages using prosper?

Look here: LINK

great, I'll try that, tnx!

...just another question:

if I'm using Outbound PHP Redirect Code, should I set up a different page to hold this code for each LP I'm testing?

I'm not sure I understand your question, can you be a bit more specific?

on prosper -> setup -> get LP code -> simple landing page ->

there's an option to cloak the aff link. In order to do that you have to set up a separate PHP file and put the given code inside. Shall I create one such file for each LP I'm testing?

I think I understand what you're asking now. You basically have to create a new .php file/page. Name is anything you want such as offer.php. Copy and paste this code into the blank .php page. Then when you send traffic from yourlandingpage.com it should be something like yourlandingpage.com/offer.php

To make it simple, yes.
