Pre-define (and keep to yourself) the definition of a successful note.

E.g.

1 booked private consultation

5 new followers

10 reposts

15 high quality comments

If the note is successful, disclose that you have zapped

x sats to each new follower

y sats for every repost

z sats for every high quality comment

If the note is unsuccessful, no disclosure but you keep the sats. (Sats are precious if this Bitcoin thing keeps working out.)

Rinse, adjust and repeat as required.
