📖 How to Use

CPC = Cost Per Click

CPC = Total Ad Spend ÷ Clicks. A core metric for search and display ads. Lower CPC means lower cost per user.

CTR = Click-Through Rate

CTR = Clicks ÷ Impressions × 100%. High CTR usually means effective creative. Industry averages: search ads 3-5%, display ads 0.5-1%.

CPM = Cost Per Mille (Thousand Impressions)

CPM = Spend ÷ Impressions × 1000. Mainly used for brand and display campaigns. Lower CPM means cheaper brand exposure.

ROI = Return on Investment

ROI = (Revenue - Spend) ÷ Spend × 100%. Positive = profitable, negative = loss. A healthy ad ROI should typically exceed 100%.
