What is a heatmap?

A visual representation of where users interact with a webpage.

In plain English

A heatmap overlays your page with colour showing where visitors clicked, how far they scrolled, or where the cursor lingered. It turns behaviour into something you can see at a glance.

They are best treated as a source of questions rather than answers. A heatmap shows you that people are clicking a non-clickable heading. It does not tell you why, and that is what you need to find out.

What to know

Click maps show what draws attention
Clicks on non-interactive elements are a strong signal that something looks like a link, or that people expect one there.
Scroll maps show how far people get
If a key message sits past the point where most visitors stop, it effectively does not exist.
Segment or it misleads
Mobile and desktop behave completely differently. A blended heatmap is an average of two unrelated experiences.
Pair with session recordings
The heatmap says where, recordings show the sequence and hesitation. Together they tell you why.

Why it matters

Heatmaps are the cheapest way to see your own site through a stranger eyes. Almost every one I have looked at surfaced at least one thing the team assumed was obvious and was not. That is a good return on a free tool and twenty minutes.

Common mistakes

×Drawing conclusions from a handful of sessions.
×Blending mobile and desktop data into one view.
×Reading a heatmap as an explanation rather than a prompt to investigate.
×Redesigning a page from a heatmap without checking the outcome afterwards.

FAQs

How much traffic do I need for a useful heatmap?

Enough for patterns rather than noise. A few hundred sessions on a page starts to be meaningful.

Are heatmaps a privacy concern?

They collect behavioural data, so disclose them and configure masking of form inputs. Consent rules apply as with other tracking.
