Also known as Key Performance Indicator.
Quick definition
A KPI (Key Performance Indicator) is a specific metric tied to a defined business objective — the number you track to know whether a goal has been met.
Metrics

A KPI is not just any metric you report — it’s a metric explicitly linked to a specific business goal, with a target, a time frame, and an owner. "Engagement rate" is a metric; "achieve a 4% average engagement rate on LinkedIn by Q3 to signal audience quality to sales" is a KPI. The target and time frame are what give it accountability. Practitioners often use the SMART framework — Specific, Measurable, Achievable, Relevant, Time-bound — to test whether a candidate KPI is well-formed enough to be useful.
Every KPI is a metric, but not every metric is a KPI. The test is whether the number is tied to a decision: if it can go up or down without changing what you do next, it’s a metric, not a KPI. Vanity metrics occupy a related but distinct category — they’re the metrics that improve easily while the thing you actually care about (revenue, qualified leads, customer retention) stays flat. A well-chosen KPI is the antidote to both over-reporting and under-reporting.
A B2B software company wants to grow its trial pipeline through LinkedIn. Instead of "increase LinkedIn followers," the team sets two KPIs: (1) 200 link-clicks per month from LinkedIn to the trial signup page, and (2) a 15% conversion rate from those clicks to submitted signups. Both numbers are measurable, tied to the revenue goal, and diagnostic — if clicks are high but conversions are low, the landing page is the problem; if clicks are low, the post strategy is.
Start from the business goal, not the platform dashboard. Map the goal to the social action that most directly predicts it — awareness goals map to reach and share of voice; consideration goals map to engagement and video completions; conversion goals map to link clicks and referral-traffic conversion rates. Limit yourself to two or three KPIs per campaign; a list of ten is a list of none. Review them on a fixed cadence and connect them explicitly to what you will change if they miss target.
