What is KPI (Key Performance Indicator)?

Also known as: Key Performance Indicator, Performance indicator

Definition

A measurable value that shows how well a specific goal is being met — for social media that could be engagement rate, reach, follower growth or click-through rate to the website.

In-depth explanation

For agencies it's crucial to define 3-5 KPIs per client rather than reporting every possible metric. Too many numbers paralyse; too few give no picture. Good KPIs are SMART: specific, measurable, achievable, realistic and time-bound.

Typical social media KPIs: follower growth per month, average engagement rate, clicks to the website, leads via DM, ROAS on paid campaigns. Which KPI takes priority depends on the goal — a brand-awareness client looks at reach, a lead-gen client at conversions.

Example from agency practice

The agency agrees on 3 KPIs with client "Garden Plant Webshop": (1) Instagram follower growth +200/month, (2) average engagement rate 4%+, (3) 50+ weekly clicks from the Instagram bio link to the webshop. The monthly report shows those three — no noise.
