I have a landing page that is underperforming and I'm about to invest in AB split testing software (or a service) Anybody got a recommendation?
You dont need software. You need a bit of php or asp and 2 adsense channels. Just drop the following php code in your page after placing the adsense codes for the two channels in the 'echo' commands. You will need to edit the adsense codes ever so slightly, replacing all instances of " (speech marks) with ' (posessive apostrophe). <?php $x = rand(1,2); if ($x == 1){ echo ("a"); // channel a code goes between brackets above } else if($x == 2){ echo ("b"); // channel b goes between brackets above } ?> Hope this helps Chris
