Thank you. I am sorry for asking this, but how changing traffic source affects my registrations? As I said before, traffic remains high. Only, now, I get far fewer registrations (i.e. yesterday I tried again, I received 0 registrations, although the site is way much much better, responsive, fast, SEO friendly, and straightforward than the previous one, which still got 0 registrations).
I also tried a small Facebook campaign and I received 10-12 registrations for $20. Which is a fairly good number. Isn't it?
