Onsite Advertiser Sign-up

Any way to know?

Is there any way to know how many advertisers are signing up through 'advertise on this site' option on our site ( Onsite Advertiser Sign-up )?

I am happy to get more business to google but I would feel better if I could know.

does it count as a $100 referal?
