CPM (cost per mille) is a bidding/pricing model where you pay per 1,000 impressions—commonly used on Google Display Network and YouTube for reach/awareness goals.

What’s the difference between CPM and vCPM?

CPM is charged per 1,000 served impressions. vCPM (viewable CPM) is charged per 1,000 viewable impressions—helpful when you care about ads being actually seen.

What is tCPM in Google Ads?

tCPM (target CPM) is a bidding strategy where you set an average CPM you’re willing to pay, and Google Ads optimizes bids to help you reach more unique users while aiming to keep average CPM around your target.

How do I calculate cost from CPM and impressions?

Use: Cost = (Impressions / 1,000) × CPM.

Is this Critical Path Method (CPM)?
