The right test for the change you're making

Run an A/B test to compare variations on one page, a split URL test to send a share of visitors to a different page, or a multivariate test to try several changes at once.

  • A/B, split URL, and multivariate
  • No-code element edits or your own code
  • Weighted variants you control
  • Target pages, devices, and dates

Measure what matters

Pick a goal and split the traffic

Choose any tracked event as the conversion goal, from form submissions to click-to-call, then decide how much traffic each variation gets. Every visitor gets one consistent experience.

Let the results settle it

Sentinel reads conversions back by variation and shows the lift with a confidence level, so you ship the version that actually performs instead of the one that sounded best.

Testing that removes the guesswork

    A/B, split URL, and multivariate, for whatever you're changing.

  • Any conversion goal

    Use any tracked event, like a form submit or click-to-call.

  • Consistent experience

    Each visitor sticks to one variation, so the test stays fair.

  • A clear winner

    See the lift and confidence level, not just raw numbers.
