I have a ? about referals

[Dznypal]

I fianlly got brave enough to use some of my points on a few rewards to use for referals but my ? is

how do you know when/if your ad went out?

this may sound dumg but like do you get the ad sent to you like everyone else?

or does the owner of the site let you know?

or all of a sudden do you have referals showing up?

I hope this makes sense

thanks
