Query RPM

Query revenue per thousand impressions (RPM) is calculated by dividing your estimated earnings by the number of queries reported, then multiplying by 1000.

Query RPM = (Estimated earnings / Number of queries) * 1000

For example, if you earned an estimated $60 from 15,000 queries, your query RPM would equal ($60 / 15,000) * 1000, or $4.00.
