If you take a look at the Progress of your Experiments, you'll see a metric called Page Views. This metric is computed for every alternative in your experiment, and it tells you how many times your visitors have seen that alternative.


This metric, however, is also shown (and used) in the Heatmap View of an alternative. Heatmaps (and Clickmaps) show the hottest areas of a page, depending on where the visitors place their mouse or where they click with it. We collect this information from as many of your visitors we can, and we organize them based on the size of their device's screen.


In principle, one may think that the Page Views of an alternative (as reported in the Progress of an Experiment page) and the Page Views of that same alternative (as reported in the Heatmaps View) should be the same. However, this is not true. In general, the number of Page Views you'll see in the Heatmaps View will be smaller, because:

  1. A visitor accesses a page, but she quits before we can track and send any information of her.
  2. A visitor accesses a page, but she does not place her mouse on the contents of that page and leaves without leaving any trace.
