There maybe a scenario where you do not want to track all of the pageviews of your visitors in Heatmaps and Session recording. To address this scenario, there is a setting called « sample rate » which will help you to control how many percentage of the pageviews gets tracked in Matomo.

You can choose a sample rate between 0.1% and 100% during Heatmap and Session recording configuration. If you choose for example 10%, every 10th pageview will be recorded, so out of 100 pageviews tracked in Matomo only 10 pageviews will be captured in Heatmaps and Session recording.
