direct linking vs lander on facebook (5)
Currently I have an ad making 50% roi by direct linkingi, but I want to see if using a lp would improve it. Is it better to just copy the campaign and test the lander vs direct linking in 2 campaigns running at the same time? Or should i just change that ads link to the lander and run it on its own?
Can't you just split test the traffic 50-50 on that same campaign by rotating between the lp and dl?
If you are using CPVLab to track you can change it directly without waiting for links to get re-approved.
Ah good point. Is it possible to do in prosper? I'm wondering if fb would be upset if I had it link to a lander suddenly like that actually, i remember reading something about bait and switching sometime ago
I'd advise creating a new campaign for testing with LP, as you said you don't wanna upset facebook if it's already working for you !

Here's one way to split test your LPs with Prosper
<?php
//Tracking202 Landing Page Rotation Script
//landing pages filenames, theses will be rotated between eachother
//theses landing pages must be in the same DIRECTORY as this file
//you can add as many landing pages here as you like
$landingpage[1] = 'landingpage1.php';
$landingpage[2] = 'landingpage2.php';
$landingpage[3] = 'landingpage3.php';
//this is the text file, which will be stored in the same directory as this file,
//count.txt needs to be CHMOD to 777, full privlledges, to read and write to it.
$myFile = "count.txt";
//open the txt file
$fh = @fopen($myFile, 'r');
$lpNumber = @fread($fh, 5);
@fclose($fh);
//see which landing page is next in line to be shown.
if ($lpNumber >= count($landingpage)) {
$lpNumber = 1;
} else {
$lpNumber = $lpNumber + 1;
}
//write to the txt file.
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = $lpNumber . "\n";
fwrite($fh, $stringData);
fclose($fh);
//include the landing page
include_once($landingpage[$lpNumber]);
//terminate script
die();
?>
