Earnings per thousand visitors (EPMV) is a metric that is used to measure the revenue generated by a website or app per 1,000 visitors. It is calculated by dividing the total earnings of the website or app by the number of visitors, and multiplying the result by 1,000. EPMV is often used to compare the performance of different websites or apps, and to evaluate the effectiveness of different revenue sources, such as advertising or subscription fees. EPMV is a useful metric for webmasters and app developers, as it allows them to track their revenue and to identify opportunities for improvement or growth.
