What is the difference between RPM and CPM?
CPM is what an advertiser pays per thousand impressions. RPM is what the publisher actually receives per thousand views after the platform takes its cut and after views that carry no ads are counted in. RPM is therefore always the lower and more useful number for a creator.
What is a good idle rpm for a car?
Most modern petrol engines idle between about 600 and 1,000 rpm when warm. Idling much higher or lurching up and down usually points to a fault rather than a design feature.
