I got it. But, when I press in the button she send me to www.link.com/0 ... that 'zero' in the end.. what can be?
I'm pretty sure it represents in which part of the program you clicked it. That is, if you click the same link in the options menu you get a 1 appended to the end instead of 0. It wouldn't be trivial to change that behaviour, so you can add something like a hashtag (#) at the end of the link or something that will make you ignore it if you don't care about it.
You can also add spaces else where.
