If you placed the ads correctly then you don't need to do anything else. your ads are not giving you revenue because they don't getting impressions. only thing you need to do is promote your faucets and get more visitors.
as soon as your ads start getting impressions you will get start getting revenue. I used a-ads ones, it is allow to use as many slots as you can.
would be better if you mention your faucet link too. we could better guide you if your ads placed wrong.
my faucet's traffic is about ~5k per day, i put many ads at top,left,right,buttom box,near captcha, get reward button but many ads do not have traffic, but today there are more ads give me revenue, thank you
