What it does

Everything A/B Tests does for you.

  • Change it without a developerPick an element by its CSS selector and replace its text, hide it, change a link or image, or add a style.
  • Whole-page testsSend part of your visitors to a different page and compare it against the original, with the address query kept.
  • Or in your own coderta.variant() tells your code which group a visitor is in, for changes the page editor cannot make.
  • No flickerVariants apply before the page shows. Each visitor keeps the same version on every visit.
  • A winner you can trustConversion, uplift and the chance each variant beats the original. A winner is called at 95% once each group has 100 visitors.
  • Keep what winsEnd the test and keep showing the winning page change or page to every visitor until you update your site.

The full A/B Tests guide

Built on your analytics

The goal is something you already track.

There is no second script and no separate testing account. Tests use the Quantalog tracking script, and a goal is any page or event that is already in your analytics.

Test views never count towards your event allowance, so testing more does not cost you more.

FAQ

Common questions.

  • No. With data-experiments="on" the tracker applies the variant before the page shows. It waits at most 0.8 seconds for the test settings, then reuses them for five minutes.

  • A visitor who saw the test and then reached your goal page or event in the same visit.

  • Pause it first. Changing a running test would mix two versions in one result.
