I realize you can register a domain name and redirect it to your affiliate link in order to hide the nasty long string of affiliate text!

But lets say that I would like to know what the actual affiliate link is and what the actual format is

So if someone sends me an email that says (go here) Example- www.gohere.com
How would I be able to tell that the link is actually pointing to Example- www.costalvacations/3/jjefferies17


Thanks
