Hotjar uses snapshots for Heatmaps, Recordings, and Form Analysis. A Snapshot is an on-demand report based on a sample of data. The snapshot size refers to the number of visitors used to generate a particular report.
So for example, if you start Form analysis, Hotjar will stop collecting data for the form when the number of visitors defined by the snapshot has been reached. If you would like to continue gathering information about your form, you will need to start a new form analysis.
Snapshot sizes for Forms depend on your plan:
BASIC - 1,000 visitors per snapshot.
PLUS - 2,000 visitors per snapshot.
BUSINESS - 5,000 visitors per snapshot.
