KPI

A KPI (Key Performance Indicator) is a quantifiable metric that measures progress toward a specific objective. KPIs answer the question: "Are we on track?" They are the vital signs of your business, team, or campaign, the handful of numbers that tell you whether things are going well or whether intervention is needed.

Why it matters: without KPIs, teams operate in the dark. They may feel busy (lots of activity) without being productive (driving outcomes). KPIs create accountability by making performance visible and measurable. They align teams around shared goals. They enable data-driven decisions by replacing "I think it is going well" with "conversion rate is up 12% month over month." Every successful marketing, sales, and product team operates with a clear set of KPIs that they track regularly.

What makes a good KPI: it should be specific (not "improve marketing" but "increase MQLs from organic traffic by 25%"). It should be measurable (you can track it accurately with existing tools). It should be actionable (the team can influence it through their work). It should be relevant (it connects directly to a business objective). It should be time-bound (measured over a specific period). This framework is sometimes called SMART goals or SMART KPIs.

KPIs by function: marketing KPIs typically include organic traffic, MQLs (marketing qualified leads), conversion rate, CAC, and pipeline generated. Sales KPIs include SQLs (sales qualified leads), win rate, deal velocity, quota attainment, and revenue closed. Product KPIs include DAU/MAU, feature adoption, retention rate, and NPS. Customer success KPIs include churn rate, NRR (net revenue retention), and expansion revenue. Executive-level KPIs include ARR, burn rate, LTV:CAC ratio, and gross margin.

Leading vs. lagging KPIs: lagging KPIs measure outcomes (revenue, churn rate, customer count). They tell you what has already happened. Leading KPIs measure activities and inputs that predict future outcomes (pipeline created, demos completed, content published). A healthy KPI framework includes both: lagging KPIs to track results and leading KPIs to predict and influence future results. If you only track lagging KPIs, you find out too late when things go wrong.

Common mistakes: tracking too many KPIs (if everything is a KPI, nothing is). Teams should focus on 3-5 primary KPIs, not 25. Not distinguishing between KPIs (the few numbers that matter most) and metrics (useful data points that provide context). Setting KPIs without establishing baselines (you cannot track improvement if you do not know where you started). Choosing KPIs that teams cannot influence. Changing KPIs frequently, which destroys trend analysis.

Practical example: a growth team sets three Q2 KPIs: increase organic traffic by 30% (leading indicator), improve free trial to paid conversion from 12% to 16% (efficiency indicator), and grow net new ARR to $250K/quarter (lagging outcome). They build a weekly dashboard tracking these three numbers. When organic traffic grows 25% but trial conversion drops to 10% in month one, they immediately redirect resources to onboarding optimization. By end of Q2, organic traffic is up 35%, conversion recovers to 15%, and they close $230K in net new ARR, missing the target but with clear visibility into why and a plan for Q3.
