KPIs and Metrics: Measuring What Matters

KPIs and Metrics: Measuring What Matters

Key Performance Indicators (KPIs) are the vital few metrics that tell you whether your business and systems are performing as intended. Choosing the right KPIs — and building the data infrastructure to measure them reliably — is one of the most valuable things we can help you do.

KPIs vs. Metrics vs. Vanity Metrics

  • Metrics: Any measurable data point — there are thousands of possible metrics in any system
  • KPIs: The metrics directly connected to your strategic goals — the vital few that matter most. Usually 5–10 at most for any given area.
  • Vanity metrics: Metrics that look impressive but don't drive decisions — page views without conversion data, follower counts without engagement

Good KPI Characteristics (SMART)

  • Specific: Clear definition — no ambiguity about what is being measured
  • Measurable: Quantifiable with available data
  • Achievable: Realistic targets based on evidence
  • Relevant: Connected to a meaningful business outcome
  • Time-bound: Measured over a defined period
