[Help] Blogspot+twitter!

Hello ,
I read that toutorial somewhere here,i just lost it

So i made a blogspot(google's free one) and a fake twitter too,

The idea is simple i spam my blog all across twitter to drive traffic and land them on my page full of adds,they click adds i earn.

Yep that's it,
Problems i ran.
i choose "a-ads" as my add source,(it gives me btc so no hassle of paypal.) i embedded it in my blog but no add are displayed

so no adds no earning,

Can someone please light me up on this thing,

IDK i should use a-ads or not,but i can't really use paypal rn.

Hope someone helps,its my first time doing ppc
