Congrats on reaching the big 100! That's a huge step!
Alright, here's the breakdown. TLDR version is that you won't make any money from ads, at least not anytime soon.
Tapas tracks both your views and your ad views - people that read your stuff with adblock on don't contribute to your ad views. If you get more than ~100 ad views in a day, you'll get ~$0.01. More ad views on that same day means more money. The count starts over for each day, so if you have 5 days in a row with 50 ad views each, you won't get anything but if you have 250 ad views on one day you'll probably get ~$0.02.
You get to keep your ad revenue but you can only make a withdrawal at $25, so if you get $0.05 per month (relatively decent), it'll only take you 42 years to get that withdrawal! I've made $0.50 from ads so far, and I had ad sharing activated in July.
So don't expect it to cover your rent or anything but accept that your story is growing - keep heart and keep working!
