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%.
