Heatmaps & Session ReplayWhat is Hotjar?
Hotjar is a product-experience platform combining heatmaps, session recordings, surveys, and feedback widgets. It shows how visitors actually scroll, click, and move through your pages.
Why Hotjar matters
Hotjar is one of the most common qualitative-analytics tools, popular because it is easy to install through GTM. That convenience is also its risk: session recordings can capture form inputs and personal data, so consent and input-masking configuration matter a great deal.

Is your Hotjar set up correctly?
- Session recording is not capturing sensitive form fields (masking is enabled).
- Hotjar waits for consent before recording EU visitors.
- The script is loaded once, not duplicated.
- Recording sampling is set appropriately so it is not silently over- or under-collecting.
