CPM, or Cost Per Mille, measures the cost of reaching a thousand people with an ad. Calculating CPM is simple: divide the total cost by the number of impressions and multiply by 1,000.

Advantages include simplicity and clarity in billing, but drawbacks include uncertainty in value and lack of consideration for conversion rates.

Despite limitations, CPM helps gauge brand awareness, audience resonance, and budget allocation. It's crucial for effective marketing decisions.
