You can split-test variations of your pages — headlines, CTAs, layouts — and measure goal and URL-based conversions to see which version performs best.

How do I know when a test has a winner?

Statistical significance is calculated automatically, so you can see when a variant is genuinely winning rather than reacting to random fluctuation.

Do I need developers to run A/B tests?

No. Tests are configured in WebGrowthSignal and share the same lightweight pixel, so you can run experiments without a dedicated engineering effort.
