Use a consistent denominator
CPL, CPC, CPA, CTR and engagement rate are only comparable when the denominator and measurement window are defined consistently.
Separate planning inputs from observed metrics
A target CPC or CTR is an assumption; actual campaign results should be measured independently and compared against the plan.
Attribution changes economics
Revenue, leads and acquisitions should be credited using a clear attribution rule before ROI, CPA or ROAS is interpreted.
Reach and impressions are different
Reach counts unique people or devices under a platform's definition; impressions count total ad displays, so frequency links the two.
Statistical significance needs uncertainty
Observed lift alone does not establish significance. Sample size, variance, test direction and confidence level all matter.
Engagement definitions vary by platform
Likes, comments, saves, shares and clicks may be counted differently, so document exactly which interactions are included.
Unit economics connect the funnel
CTR affects clicks, conversion rate affects acquisitions, and CPC/CPA determine how efficiently spend moves through that funnel.
Scenario analysis is not a guarantee
Forecasts are useful for planning, but auction prices, seasonality, audience quality and measurement error can shift real outcomes.
