It is good practice to diversify your ads and make the most of the ads on our network.

We have seen Publishers with little daily traffic earn more than others with lots of traffic.

The secret is to integrate ad sizes that most Advertisers target for their ads.

There are banner units that don't have CPM ads, while there are some that usually have CPM based ads.

Test different banner units and see which helps you make more money.

Good luck!
