Viral Facebook Video Ad Question! URGENT

So I have a video going viral right now currently sitting at 3.4 million views, how can I use facebook ads to boost it even more and convert it? I'm driving the traffic to my website.
I'm not trying to pay even .01 cents per view because it's not worth it since it's blowing up, but I want to see if it's possible to pay per thousand views or something. Any advice?

Unfortunately no guru replied. But I also have similar question. I don't seem to be able to convert those viral clicks though. But I am getting cheap US traffic like 0.05 CPC. Changed product several times to no avail.
