Heatmap
Experiment heatmaps
A heatmap for every variant of your GrowthBook experiments, and two variants side by side.
What you see
Your GrowthBook experiments in Historian, running and finished. Each one shows what is being tested, with the variants as Historian captured them, GrowthBook's own results, and the most clicked elements per variant.
Each variant has a heatmap of its own: the clicks from every page where visitors saw that variant. Open two of them side by side to see how the variants are used differently.
How it works
Historian reads your experiments from GrowthBook with a read-only key. Your GrowthBook setup tells Historian which variant each visitor saw, and Historian captures the tested page once for every variant. We set up the experiments with you.
Why it matters
An experiment tells you which variant won. It does not tell you why. The heatmaps show what visitors did differently: which element the winning variant got them to click, and which one the losing variant lost them on. That is what the next experiment is built from.
An example
A test of a shorter product description wins by a small margin. The variant heatmaps show why: with the shorter text, the size selector moved above the fold and got far more clicks. The next test is about the size selector, not the text.

Heatmap overview →Time Machine
Go back to any version of a page, with the heatmap for exactly that version and a written summary of what changed.
Version comparison
Put two periods or two versions of a page side by side, each with its own heatmap and its own numbers.
Revenue per click
Colour the page by what a click on each element brings in, not by how often it is clicked.
Click products
See which products were bought by the visitors who clicked an element.
Click transitions
See which pages visitors went to after they clicked an element, and what those visits were worth.
Template heatmaps
Add up the same element across every page built from one template, and see where it works and where it doesn't.
Element drill-down
Click any element on the heatmap and follow its numbers day by day, with the days it changed marked on the chart.
Heatmap metrics
Eleven metrics for every element on the page, from clicks to revenue per click. Colour by one and show the numbers of another.
Mobile vs. desktop
See the heatmap for mobile visitors and for desktop visitors, and how the same page works on each.
Traffic segments
Filter the heatmap by where the visitors came from, and see how each channel uses the page.
