@talanhorne,
Once I did online marketing and promotions! Moreover, I had advertising based revenue sharing ponzi scheme! (Yeah I mean it Ponzi, but it was the ponzi scheme refunded all investors - adpack buyers before site shut down)
I did few promotions to get more people in there! It worked, but costly! So this is better, coz you are not making money by your site! You are looking for more audience! And you need an audience who wish to read them, not to display and just left them! So this is better!
Congratz for the achievement! I think 2019 will be a successful year for all of us!

Cheers~
