Either you keep count of how many people you redirected and change the link's target accordingly, or you can use the power of statistics and generate a random number between 0 and 1 - then redirect the user to A if it's less than 0.2, to B if it's between 0.2 and 0.7 and otherwise to C. That way, it also doesn't matter if you have 200k visitors or only 100 - statistically, 20% will go to A, 50% to B and 30% to C.
