If you would like your Heatmaps to be automatically recreated on an ongoing basis, you can select this option to enable recurring Heatmaps. Crazy Egg will automatically create a new Heatmap when the current one ends.
For example, if you launch new content on your site every month, you can set up a Heatmap to track for 60 days OR 25,000 visits and then select the recurring Heatmaps option. Once the current Heatmap reaches the duration limit, a new Heatmap will be automatically created using the same duration limits (X days, Y visits).
