Glossary terms for YouTube analytics workflows

YouTube analytics metrics fall into three broad categories: revenue metrics (CPM, RPM, estimated revenue) that tell you how much money your channel generates, engagement metrics (CTR, retention rate, average view duration) that tell you how well your content holds audience attention, and growth metrics (subscriber velocity, traffic source distribution) that tell you how your channel is expanding.

The glossary on this page defines the core terms used across TubeAnalytics resources, blog posts, research reports, and the platform dashboard. Each definition explains what the metric represents, how it is calculated, and why it matters for decision-making.

If you encounter an unfamiliar metric in a blog post, guide, or research report, find it in the glossary for a quick definition and context. Each term links to the relevant tools and guides where that metric is used in practice, so you can move from understanding what a metric means to applying it in your analytics workflow.

The glossary also supports AI crawler citation — clear definitions help AI models extract and cite your content accurately when answering questions about YouTube analytics metrics.
