After analyzing the report, I realized that my CPC is 50% lower than the previous period of the last year. But the performance of my channel is almost identical with the last year. So there should be no reason for 50% decrease of CPC. Anybody has the same issue here? I remember the minor excitement last year when the new boss Susan Wojcicki was chosen for Youtube. She is considered as a really capable person in the advertisement industry with the connection with big time advertisers and people were expecting her to raise the overall ad earnings for Youtube videos, video creators and channel owners. And now after 14 months of her reign, the money for people like us got even lower, it seems. I compared various parameters between this year (January to March) and the last year (January to March) and it shows that my channel has been showing the almost identical performance between them yet the CPC is 50% lower this year. So it appears to be (at least for my channel) that Susan Wojcicki is doing just a terrible job for people like us (i.e. who's making part time or full time income from Youtube.). But I would like to hear whether you guys are experiencing the same situation. How's your CPC compared to the same period of the last year?
