I'm still new to the topic, just over a month with Clickadilla. I chose this advertising network because of the low cost of impressions, it was first necessary to get into everything. At first there were difficulties in the settings, but with the clear interface of the site and operational support was able to quickly enough to understand everything.

I was pleased with the results, the conversion is higher than I expected. All suspicions of budget drainage are not justified, in any case, they did not affect me. If you fully understand the settings of the network, there is no problem. Here are my screenshots:
