Every fix from a Polaris report can go straight into an experiment on the same data — with a calculator built in, so "it worked" has to survive a Wilson interval, not just a hopeful glance at the dashboard.
Classic split URL redirect for full-page variants — simplest setup, works on any stack.
DOM-level variant swaps for React/Vue/single-page apps, without a full reload breaking app state.
Variants that activate on a specific event — a click, a scroll depth, a cart state — not just page load.
Run a test on one URL pattern, one traffic source, one device class — or stack conditions to reach exactly the segment the report flagged.
Split traffic 50/50, or route more traffic to a promising variant early and adjust — the calculator recalculates sample size either way.
The same math the Experiments module uses internally: Wilson confidence intervals, not raw percentage differences. Plan a test before you launch it, or check whether a result you're already seeing is real.

Wilson 95% CI — A: — · B: —
Uses a two-proportion z-test (α = 0.05, 80% power) for planning, and a Wilson score interval for the significance check. For guidance, not a replacement for your own statistician on high-stakes decisions.
