Here’s everything you need to know: what it is, why it matters, how to calculate it, and how to optimize it! **1 min** read ## What is Cost Per Thousand (CPM)? Cost Per Thousand (CPM) is an advertising metric that represents the cost of delivering 1,000 impressions of your ad. It’s widely used in display, video, and programmatic advertising to assess cost-efficiency for visibility-driven campaigns. ## Why Is CPM Important? CPM helps advertisers understand how much they’re paying for brand exposure. It’s especially important for campaigns focused on reach, awareness, or viewability rather than direct response. ## How to Calculate CPM Divide your total campaign cost by the number of impressions (in thousands) to get your Cost Per Thousand. ## The Turning Point OWOX Data Marts See your first report built in real time. _15 minutes._ 1.

[Book a Demo](https://www.owox.com/demo) We'll use your actual use case ## The CPM Formula: CPM = (Total Cost ÷ Total Impressions) × 1,000 ## Example of CPM in Action If you spend $500 on a campaign that gets 100,000 impressions, your CPM is ($500 ÷ 100,000) × 1,000 = $5. This means you paid $5 per 1,000 views. ## Optimize Your CPM with OWOX Data Marts OWOX Data Marts connects cost and impression data across platforms, helping you track CPM by audience, format, and device. Use these insights to improve efficiency and maximize exposure. ## What Is a Good CPM? A good CPM depends on your industry and platform, but generally ranges between $2–$10. Lower CPMs paired with high visibility mean strong efficiency. ## What Is a Bad CPM? A high CPM with low engagement may signal ineffective targeting or expensive placements that don’t deliver value. ## Best Practices for CPM Use these strategies to keep CPM low while maintaining ad quality. ### Target Smartly Avoid overly broad targeting—refined audience segments can lower CPM while increasing relevance. ### Test Creative Formats Compare static, carousel, and video formats to find which drives impressions at the best cost. ### Monitor Placement Performance Review platform and device-level CPM to remove underperforming placements. ## Common Mistakes to Avoid with CPM Don’t optimize for low CPM alone—focus on both visibility and post-impression performance like clicks or conversions. ## Topics [Metrics](/marketing-metrics) ## Related metrics ## Related metrics you might be interested in [![Google Ads Impressions](https://cdn.owox.ai/www/content-marketing-marketingmetrics/google-ads-impressions/ogimage/1.png/public)Google Ads Impressions](/marketing-metrics/google-ads-impressions) [![Google Advertising Costs](https://cdn.owox.ai/www/content-marketing-marketingmetrics/google-advertising-costs/ogimage/1.png/public)Google Advertising Costs](/marketing-metrics/google-advertising-costs) [![Google Analytics Traffic](https://cdn.owox.ai/www/content-marketing-marketingmetrics/google-analytics-traffic/ogimage/1.png/public)Google Analytics Traffic](/marketing-metrics/google-analytics-traffic) [![Impression Share](https://cdn.owox.ai/www/content-marketing-marketingmetrics/impression-share/ogimage/1.png/public)Impression Share](/marketing-metrics/impression-share) ## Related articles ## Learn more about analytics [![The most expensive queue in your company is in front of your one data guy](https://cdn.owox.ai/www/content-marketing-article/data-team-bottleneck/thumbnail/2.png/public)data analyticsThe most expensive queue in your company is in front of your one data guyJul 14, 2026](/blog/articles/data-team-bottleneck) [![What is Cost Per Click in Advertising: CPC Formula and Calculation](https://cdn.owox.ai/www/webflow/69ea498e81f33e072f06cf5e_CPC-IN-ADVERTISING.png/public)marketingWhat is Cost Per Click in Advertising: CPC Formula and CalculationApr 8, 2026](/blog/articles/what-is-cpc) [![Understanding BigQuery Pricing: A Complete Cost Prediction Guide](https://cdn.owox.ai/www/webflow/696a7853c0aa8783779dbcc4_BIGQUERY-PRICING-COST-PREDICTION.png/public)bigqueryUnderstanding BigQuery Pricing: A Complete Cost Prediction GuideAug 5, 2024](/blog/articles/bigquery-pricing) ## Customer stories ## Learn how teams ship analytics faster Organizations that scaled analytics without scaling headcount [All case studies →](/blog/success-stories) [!["For 10 years I was blind."
