Solutions

For CRO teams

Find what to test next, see what every change did, and know what a click on each element is worth.

Heatmaps on every version of the page

Historian keeps every version of your pages, so the heatmap is drawn on the page as it looked on the day, not on today's page. Compare two versions side by side, and see what moved.

Colour the page by clicks, conversion or revenue per click, and click any element to see its revenue, clicks and converted clicks day by day, the products bought after the click, and where visitors went next.

Two versions of the same page side by side, before and after a change

Templates, devices and traffic

Look at one template across all its pages to find the element that underperforms everywhere. Split the heatmap by device and by traffic source, because a mobile visitor from a paid campaign is not a desktop visitor from your newsletter.

Experiments with a heatmap per variant

Connect GrowthBook, and Historian captures every variant of your experiments and draws a heatmap for each, side by side, next to GrowthBook's own results. You see not just which variant won, but what visitors did differently.

A backlog the agents keep full

The A/B Test Opportunity Finder ranks what to test next by revenue at stake. The CTA Optimisation Advisor, the Mobile UX Gap Agent and the Template-Wide Fix Advisor find the specific elements and templates worth your next sprint.
