Key Performance Indicator (KPI)
A key performance indicator (KPI) is a measurable value that demonstrates how effectively a business or campaign is achieving its strategic objectives.
KPIs are the measurable metrics that track progress toward goals, such as open rate, CTR, or revenue per send.
Definition and examples
Key performance indicators (KPIs) are quantifiable metrics used to evaluate the progress toward specific business goals. By tracking KPIs, organizations can gauge how well their activities align with broader objectives and identify areas for improvement. KPIs exist at different levels: high-level KPIs may track overall company performance (such as annual revenue growth or churn rate), while low-level KPIs monitor the effectiveness of teams or campaigns (like email open rates, click-through rates, conversion rates, or customer lifetime value).
Why it matters
It matters because KPIs keep teams focused on outcomes that actually matter instead of vanity metrics that look busy but do not change the business.
Common mistakes
A common mistake is tracking vanity metrics over outcomes, like opens without revenue. Another is tracking too many KPIs at once and losing focus. Keep levels separate: high-level KPIs (annual revenue growth, churn) belong on company dashboards, while low-level KPIs (open rate, click-through rate, conversion rate) measure teams and campaigns. Good KPIs are specific, measurable, achievable, relevant, and time-bound. Measuring them regularly helps marketers make decisions based on data instead of instinct.
