App advertisers, publishers, and businesses can utilize eCPMs to optimize their <a href=\"https:\/\/adjoe.io\/solutions\/monetize-your-app\/\" target=\"_blank\" rel=\"noreferrer noopener\">monetization<\/a> strategies.<\/p>\n\n\n\n<p>The higher the eCPM, the more effectively you generate revenue from your ads. Once you know how much you are generating per impression, you can review different revenue streams and work to improve your eCPM. Use eCPMs in a particular tier as a baseline to measure performance from one tier to another.<\/p>\n\n\n\n<p>While eCPM is a key metric for publishers to consider, they should monitor it in combination with other metrics, such as <a href=\"https:\/\/adjoe.io\/glossary\/what-is-arpdau\/\" target=\"_blank\" rel=\"noreferrer noopener\">ARPDAU<\/a> or ARPDEU. The other thing to note is that eCPMs are measured differently within the adtech industry, as not everyone\u2019s definition of an ad impression is exactly the same.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img decoding=\"async\" src=\"https:\/\/adjoe.io\/app\/uploads\/2023\/09\/Progression-of-eCPMs-per-tier-1024x780.jpg\" alt=\"line graph showing progression of eCPMs in Tier 1, Tier 2, Tier 3\" class=\"wp-image-56471\" width=\"910\" srcset=\"https:\/\/adjoe.io\/wp-content\/uploads\/2023\/09\/Progression-of-eCPMs-per-tier-1024x780.jpg 1024w, https:\/\/adjoe.io\/wp-content\/uploads\/2023\/09\/Progression-of-eCPMs-per-tier-300x229.jpg 300w, https:\/\/adjoe.io\/wp-content\/uploads\/2023\/09\/Progression-of-eCPMs-per-tier-768x585.jpg 768w, https:\/\/adjoe.io\/wp-content\/uploads\/2023\/09\/Progression-of-eCPMs-per-tier-1536x1171.jpg 1536w, https:\/\/adjoe.io\/wp-content\/uploads\/2023\/09\/Progression-of-eCPMs-per-tier-2048x1561.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How Do I Calculate eCPM?<\/strong><\/h2>\n\n\n\n<p>The formula for calculating eCPM is straightforward. Simply take the ad revenue and divide it by the number of impressions. You then multiply this to determine the effect of a specific ad per 1,000 impressions.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img decoding=\"async\" src=\"https:\/\/adjoe.io\/app\/uploads\/2023\/08\/effective-cost-per-mille-1024x511.jpg\" alt=\"how to calculate eCPM\" class=\"wp-image-54445\" width=\"910\" srcset=\"https:\/\/adjoe.io\/wp-content\/uploads\/2023\/08\/effective-cost-per-mille-1024x511.jpg 1024w, https:\/\/adjoe.io\/wp-content\/uploads\/2023\/08\/effective-cost-per-mille-300x150.jpg 300w, https:\/\/adjoe.io\/wp-content\/uploads\/2023\/08\/effective-cost-per-mille-768x383.jpg 768w, https:\/\/adjoe.io\/wp-content\/uploads\/2023\/08\/effective-cost-per-mille-1536x767.jpg 1536w, https:\/\/adjoe.io\/wp-content\/uploads\/2023\/08\/effective-cost-per-mille-2048x1022.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">How Do You Optimize eCPMs?<\/h2>\n\n\n\n<p>An ad could receive an impressive number of impressions, but at the end of the day, if users aren\u2019t engaging with an ad, they will not generate the desired revenue.&nbsp;<\/p>\n\n\n\n<p>In these cases, publishers must identify initiatives to increase engagement with their ad.

Advertisers use CPM as a cost model for how much they will pay for 1,000 impressions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>FAQs<\/strong><\/h2>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1646153625669\"><strong class=\"schema-faq-question\">What Is eCPM Advertising?<\/strong> <p class=\"schema-faq-answer\">eCPM means \u201ceffective cost per mille,\u201d a metric used to measure and predict ad revenue.
