Heatmap Sample Size

Hello,

Very easy, basic question that I couldn't find an answer to with a forum or site search.

I was thinking of upgrading my site plan and am curious what the heatmap samples sizes mean? Is it the percent of visitors that are tracked?

Thanks.

Yes. Percentage of visitors sampled.
