Revenue per page view ("RPM") – represents the advertising revenue earned per 1,000 pageviews. It is calculated as our advertising revenue during a period divided by our total page views during that period and multiplied by $1,000; and
Monthly average pageviews – represents the total number of pageviews in a given month or the average of each month’s pageviews in a fiscal quarter or year, which is calculated as the total number of page views recorded in a quarter or year divided by three months or 12 months, respectively.
We monitor and review our key operating metrics as we believe that these metrics are relevant for our industry and specifically to us and to understanding our business. Moreover, they form the basis for trends informing certain predictions related to our financial condition. Our key operating metrics focus primarily on our digital advertising revenue, which is our most significant revenue stream. Management monitors and reviews these metrics because such metrics are readily measurable in real time and can provide valuable insight into the performance of and trends related to our digital advertising revenue and our overall business. We consider only those key operating metrics described here to be material to our financial condition, results of operations and future prospects.
For pricing indicators, we focus on RPM as it is the pricing metric most closely aligned with monthly average pageviews. RPM is an indicator of yield and pricing driven by both advertising density and demand from our advertisers.
