Here’s a code I use over on ListPlaybook.com to rotate 4 different landing pages.
It’s much faster than starting and stopping Google’s tool every time I want to make a small change or add another page.
All you have to do is put this code in your index.php and then all the links in here will rotate randomly and show the visitor those other pages on a random rotation. You can have more or less than 4, just add or remove another as necessary.
Here’s the code (don’t forget to wrap it in PHP tags):
$sites = array(
$randomSite = array_rand(array_flip($sites), 1);
This will make index.php rotate to promo1/, promo2/, promo3/, and promo4/ on a random rotation (which at the end of the day is evenly rotated.)
