CPM, CPC, and RPM are core metrics in Blogging, Social Media and digital advertising, measuring ad performance, costs, and creator earnings. They help optimize revenue by balancing views, clicks, and advertiser bids, with examples tied to niches like finance ($15+ CPM) vs. gaming ($5).
Key Metrics Definitions
- CPM (Cost Per Mille/Thousand): Advertiser cost or creator earnings per 1,000 ad impressions (views). Formula: (Total spend / Impressions) × 1,000. Example: A finance video gets 100K views at $20 CPM = $2,000 revenue before cuts.
- CPC (Cost Per Click): Advertiser payment per ad click. Formula: Total spend / Clicks. Example: $1 CPC with 500 clicks = $500 spend; useful for targeted Shorts hooks.
- RPM (Revenue Per Mille/Thousand): Creator’s net earnings per 1,000 views after YouTube’s 45% cut (RPM ≈ 55% of CPM). Formula: (Total revenue / Views) × 1,000. Example: $20 CPM yields ~$11 RPM in English personal finance.
