What is CPM and Why Does It Matter?
CPM stands for **Cost Per Mille** (Latin for "thousand"). In digital advertising, it represents the price of 1,000 advertisement impressions on one web page or video. If a publisher charges a $10.00 CPM, an advertiser must pay $10.00 for every 1,000 times the ad is shown.
For content creators targeting Tier 1 countries (like the US, UK, and Canada), understanding CPM is critical for maximizing revenue. High-value niches such as finance, real estate, and technology often command significantly higher CPMs than general entertainment. Use this tool to verify your ad earnings or to budget for your next marketing campaign across Google Ads, YouTube, or Facebook.
