Startapp ads revenue

I am using startapp banner ads in more than 8 app and fill rate is 99%. My all apps has 1118 impression and 25 clicks in last 90 days but then also my revenue is 0. Anyone have the solution why my is revenue is 0.
Thank You

Because its bad

What is bad

You should move to applovin its 100 times best from startapp and second thing is your app publish startapp asks link for app.

I have applied for applovin but I email id has been disabled.

That’s disappointing try from another email

At what level will your revenue start increase your Ng?
