hi guys, I'm new here. Wanted to ask a question. Here's a website that runs ads only:
http://example.com/

First link you can see is Super Cheap Travel Sites and if you right click, you see something like this:

http://example.com/redirect.php?then goes googleadssite.com

How did they create this redirect link?
