3. Ad Pricing Models — CPM, CPC, CPV (what they mean)

CPM — Cost Per Mille (per 1000 impressions)

Advertisers pay per thousand views. Publishers earn based on impressions and the rate (RPM).

CPC — Cost Per Click

Advertisers pay when a user clicks an ad. Publisher revenue depends on click-through rate (CTR) and CPC amount.

CPV — Cost Per View (video ads)

Used for video ads or interactive formats.

Simple revenue math

Example (CPC): 10,000 visitors, average CTR 0.5% (0.005), clicks = 50. If average CPC = ₹8, revenue = 50 * ₹8 = ₹400.

Example (CPM): 100,000 pageviews, RPM (revenue per 1000 pageviews) = ₹120 → Revenue = (100,000 / 1000) * 120 = ₹12,000.
