Analytics glossary. Product analytics terms explained.

Plain-language definitions of the terms you meet when you measure how people use software, written by the team behind smolanalytics. Each one opens with a short definition, then links to a full page.

The smolanalytics glossary explains the product analytics terms that show up when you measure how people use software: product analytics itself, funnel analysis, retention, cohorts, paths, and newer ideas like an MCP analytics server (a way to ask your analytics in plain English from a coding agent). Each entry opens with a short, plain-language definition you can lift verbatim, then explains what the term means, when it matters, and how it works in practice, with no marketing spin. The glossary is written by the team behind smolanalytics, an open-source (MIT) web and product analytics tool that computes these metrics from your own events, so the definitions describe how the numbers are actually calculated, not a vendor's idealized version. Every term links to a full page, and the pages cross-link so you can follow a concept (say, from funnel analysis to retention to cohorts) without leaving the site. Start with product analytics if you are new to the space.
