When do fluctuations in CPMs typically happen?
CPMs don’t fluctuate, they are a fixed value across the year.
They dip at the end of the year and rise at the beginning of the year.
They rise at the beginning of the quarter and dip at the end of the quarter.
CPMs rise at the end of a quarter and dip at the beginning of a quarter.
There are many factors which influence CPM’s. For example, industry, geographic location, macro trends, season and so on. In general, we can divide these factors into global supply and demand factors, advertising industry factors, and YouTube specific factors.
So, if we ask when do fluctuations in CPMs typically happen, we keep in mind advertising industry factors in mind. Trends and season can influence ad spend and ad revenue for YouTube channels as a result. As a general rule, advertisers tend to spend more money at certain times of the year, like holidays, sporting events and so on. Also, CPMs tend to be highest towards the end of each financial quarter. And, drop with the start of the next quarter.
However, this is just a general rule. Depending on your channel’s specific CPM’s not follow general trends.
