I think it could matter. You should always use the exact link given to you by the affiliate program. If you alter it, there’s no telling whether or not your referrals will be tracked. Best to use exactly what they give you.
You can add a forward slash at the end of a full domain name, for example:
[HTML]www.choicegambling.com[/HTML]is the same as
[HTML]www.choicegambling.com/[/HTML]But if you have a dynamic URL, things are different. For example:
[HTML]www.choicegambling.com/casinos.php?name=casino-del-rio[/HTML]is not the same as
[HTML]www.choicegambling.com/casinos.php?name=casino-del-rio/[/HTML](Note the forward slash at the end of the second link.)
The first link works; the second link takes you nowhere.
Hope that helps.
