A treemap is a visualization that uses nested tables that represent a hierarchy (tree) of your data. Each block represents a branch of the tree and contains smaller blocks that represent its “children” or sub-branches. At each level, the relative sizes and colors of the blocks represent the relative values of your selected metrics.
The default Treemap in GA shows your acquisition channels (defined in the Default Channel Grouping), compared by sessions and pages/session. You should interpret the report as follows:
- The larger the block, the larger the proportion of sessions for that Channel
- Channels with higher pages/session are shown in shades of green (deeper green indicates higher pages/device)
- Channels with the lower pages/session are shown in shades of red (darker red means lower prices)
In usual, higher blocks indicate higher proportions of the primary metric (e.g. sessions, events, new users), while greener blocks design more favorable values of the secondary metric (e.g. sheets/session, bounce rate, avg. session duration).
