The Vanity Metric Trap
Followers, likes, page views, impressions — these numbers look good in reports but rarely correlate with business results.
The Only Metrics That Matter
Measure Customer Acquisition Cost (CAC), Customer Lifetime Value (CLV), and the CLV:CAC ratio. A ratio above 3:1 means your marketing is profitable.
Attribution: The Hard Part
Most businesses under-attribute content and SEO and over-attribute last-touch channels. Multi-touch attribution gives a far more accurate picture than last-click models.
