After clicking on a Call to Action button, you will notice the URL in the address bar looks like it has many more characters (letters, numbers, symbols) than your landing page URL normally contains. These extra characters are the tracking code applied to the URL only after clicking on a Call to Action button.
It looks something like this:http://www.myawesomesite.com/landing-page?__hssc=85760070.1.1481727313232&__hstc=85760070.1248059780332a83f066c77aa4b8e585.1479138352890.1481654254241.1481727313232.6&__hsfp=3631117429&hsCtaTracking=23dc18c3-da2a-4117-88e2-075d1f2f5524%7C39532b9f-b6b9-457e-9590-4efa408620bb
This lengthy URL is not the new permanent URL, but is necessary in order for the software to register visits, submissions, and clicks in the CTA dashboard and data table. The _hssc, _hstc, and _hsfp parameters are used for cookie tracking. Read more about those parameters here. The hsCtaTracking parameter is specific to CTA tracking.
