Hotjar Explained: Heatmaps & Session Recordings

Hotjar is a behaviour-analytics and feedback tool — heatmaps, session recordings and on-site surveys that show how and why visitors use your site.

What the site ID means

Hotjar identifies your site with a numeric site ID (hjid), loaded from static.hotjar.com.

What you get

• Heatmaps of clicks, moves and scroll depth
• Recordings of real sessions
• Surveys and feedback widgets

Why it matters

Analytics tells you what happens; Hotjar shows you why — invaluable for spotting UX problems that numbers alone miss.

How to check yours is working

Run your site through our free Tag Explorer tool — it shows every tag on the page, nested under its GTM container, with the tracking IDs. To confirm a tag actually fires, use GTM’s Preview mode or your browser’s DevTools Network tab.
