Analytics dimension

Metrics answer how much. Dimensions answer by what. Views is a metric, and views by country, views by traffic source and views by device are that same metric cut three ways. YouTube Studio works this way in every report: pick a metric on the chart, pick a dimension on the tabs underneath, read the rows. Most useful analysis comes from choosing a better dimension rather than hunting for a new metric. A retention problem that looks flat overall often splits hard by traffic source, with search viewers staying and browse viewers leaving. One caution: dimension rows will not always add up to the headline total because some views cannot be attributed.
