Is there software to install? Do I have to control the URL?

There is no software to install. We monitor and verify our clickers' activity on our end, using our proprietary browser extension.

You do not need to control the URL to create a click order. There is no software to install, and our clickers will search for whatever keyword phrase you tell them and will click on whatever URL you specify, whether or not it is yours. 

In fact, a common usage our our service for Online Reputation Management involves creating multiple orders for multiple different third-party URLs.
