73%Likelihood to Win

The score ranks an idea against your own backlog; it is not a win probability in the strict sense.

How the score works

Your idea, checked against tests that already ran

4.3 million A/B tests from 151,000 shops, over 4,000 of DRIP's own tests, and your own results.

  1. An idea card, Show honest stock information above Add to bag, beside a phone with a low stock line on the product page
    01

    You add an idea

    Type it in plain words, like “show low stock above Add to bag”.

  2. A field of shop marks on a starry background: the shops that ran a similar test
    02

    Apex finds shops that tested it

    It looks at what similar tests changed and which versions shops kept.

  3. The Apex backlog: six ideas ranked by Likelihood to Win, the new idea on top
    03

    Your backlog sorts itself

    Every idea gets its Likelihood to Win. The ones with a chance go first.

Guardian

A test that loses still costs you

Half your visitors see the losing version. Guardian pauses it at the limit you set.

Revenue per visitor: the variation's bar falls short of the original, the gap hatched in red; under it the estimated loss runs up to your limit
The variation earns less per visitor

Questions about the score

Is the Likelihood to Win a win probability?

No. The score ranks an idea against your own backlog; it is not a win probability in the strict sense. Use it to decide what to build next.

Where do the tests come from?

From observed tests. An A/B test changes the page that real visitors see, and we observe it. That is how 4.3 million A/B tests from 151,000 online shops came together since 2011, one of the largest A/B test databases in e-commerce.

What if the odds are wrong?

Then the test loses on part of your traffic, not all of it. Guardian pauses it when a variation gets no conversions while the original converts, or clearly converts worse.

Can I adjust the score?

For managed clients, a DRIP consultant can move it by a few points when they know something the data does not.

Is it free?

You get 30 days free, without a card. After that your shop moves to the free plan, so there is nothing to cancel. The full terms are on the sign-up page.
