This part is surprisingly easy.
Now that you’ve chosen the information you’d like to send through to your landing page, you just need to insert a few corresponding snippets of PHP code to receive that information and do something with it.
On the Landing Pages tab you can grab a page of code to modify, or you can just scroll down to the very bottom for the snippets themselves.
Copy a snippet and paste it into your page where you want the information to be displayed. For instance, if you want your full (“final”) keyword to be your page heading, you would change the code in your page to something like this:
<?php echo str_replace('-', ' ', $_GET['final'])?>
