# Heatmaps

> Four overlay layers painted on your real site, for everyone or for one person.

**Heatmaps** has its own entry in the left menu, under Insights. A heatmap is drawn over **your own site**, not inside Behavly. The **Heatmap** button opens your tracked domain in a new tab with an overlay painted on top of the real, live page. With several tracked sites you pick one first.

#### The Four Layers

_The Heatmaps page, where you pick the tracked site and the layer before the overlay opens on your own page._

- **Clicks**: Where people clicked.
- **Movement**: Where the pointer lingered.
- **Scroll**: How far down each page people got.
- **Elements**: A count per button or link, matched by its CSS selector — so the count survives a redesign that moves the element somewhere else on the page.

#### Per-Person Heatmaps

Every row in the Identified and Anonymous lists has its own heatmap button. It opens the same overlay scoped to that one person, across every browser they used.

#### Viewing Links Expire

The overlay reads from a short-lived viewing link that expires after **30 minutes**. If the overlay stops loading, open it again from Behavly to mint a fresh one. The link is short-lived on purpose: it grants read access to behavioural data, and a URL that lives in someone's browser history forever is a URL that leaks.

> Warning: The overlay only shows what the snippet recorded on that page. A page the snippet is not installed on has no heatmap — it will open and paint nothing, which looks like a bug and is not one.

> Note: Most visitors never scroll far, so scroll and click data thin out sharply below the fold. That is a property of your visitors, not of the overlay.
