Key Performance Indicator (KPI)
A specific, measurable number that shows whether you're making progress toward a goal that actually matters to the business.
Definition
A Key Performance Indicator is the handful of metrics you watch because they map directly to a business outcome you care about. A true KPI is tied to a goal, has a target, and changes how you act when it moves.
In depth
Not every number is a KPI. Analytics tools spit out hundreds of metrics, but a KPI is one you've deliberately chosen because it tracks something that moves the business, leads booked, cost per acquisition, return on ad spend, revenue. The test is simple: if the number changes, would you do something differently? If not, it's a vanity metric, not a KPI.
Good KPIs keep a team honest and focused. They give everyone the same definition of success, make it obvious when a campaign is winning or losing, and stop arguments that run on opinion instead of evidence. The best ones sit close to money, leads, sales, and lifetime value, rather than upstream proxies like impressions or follower counts that feel good but don't pay the bills.
The trap is tracking too many KPIs, or picking ones that are easy to measure instead of ones that matter. We help clients narrow to a short list, usually three to five, that ladder up to revenue, and we attach a target to each so the number means pass or fail, not just a figure on a dashboard. A KPI without a goal is just a metric.
Worked example
For a roofing company, 'cost per booked inspection under $120' is a KPI; total website pageviews is a vanity metric that doesn't change how the business spends.
