A short, source-backed explanation of the metric behind most publisher revenue planning.
Page RPM is the cleanest planning metric for publishers because it connects pageviews directly to estimated revenue.
Guide
Google defines Page RPM as your estimated earnings divided by pageviews, multiplied by 1,000.
That makes it one of the fastest ways to judge how efficiently a pageview is being monetized.
If your traffic grows but RPM falls, your monetization quality may be weakening even when top-line views look healthy.
Guide
RPM is easier to plan around than CPC because it already captures the combined effect of impressions, clicks, and advertiser value.
It is also useful for communication: product, editorial, and ad ops teams can all align around one number tied to actual revenue output.
Guide
Look at trend direction before reacting to one week. RPM can swing with seasonality and campaign cycles.
Then segment your traffic by geography and source. A mixed traffic shift can move RPM even when your page layout did not change.
Guide
RPM alone does not explain the root cause of a change. It tells you what happened, not why it happened.
For diagnosis, review geography mix, ad density, viewability, session depth, and monetized impression quality together.
