It is easy for publishers, it has great reporting capabilities with detailed insights about their performance in real-time as well as historical data of up to 3 years! The UI could be more user friendly but I believe that they are working hard towards this goal now so we can expect improvements soon :) Highly recommended if your looking into CPC bidding networks or just starting out using one because there's no better option than Clickstar right here at its best price point (currently $0). We use click star mainly from traffic sources like social media posts where sometimes organic CTRs aren't enought/available when targeting certain keywords which results usually in low impressions per day even though high clicks would work fine. So by adding paid ads through Clicksparnetworks such problems disappear completely since both types(organic & payed) contribute equally thus reaching goals faster while not having any impact on conversions negatively.
