Why it works
The story follows a tight hypothesis-test-result loop, which gives the mechanism real credibility. The before-state (low mobile conversions, no obvious cause) sets up the heatmap discovery phase cleanly, making the Clarity element a genuine precursor to the Breakthrough result. The single metric is specific and tied directly to the test, not a vendor-wide claim.
Steal this
Show the control versus variation side by side with a named hypothesis before revealing the result. It lets readers evaluate the logic independently and makes the outcome feel earned rather than asserted.
