Predictive A/B Testing: What It Actually Means, and What It Cannot Do
Make more revenue from the traffic you already pay for. A guide to Prediction-Based Experimentation ↓ We know what shops like yours tested and which tests won.
Free. Five quick questions, then it's yours.
What's inside
What you get
That knowledge helps you decide which ideas to build and test in your own shop, before committing design, development, and traffic.
This whitepaper explains how that works, what a prediction can tell you, and where its limits are.
Here’s what’s inside:
1/ What “predictive” actually means
The difference between evaluating an idea before you build it and changing how a test runs after launch.
2/ How past tests inform your next move
How results from comparable shops help you assess a test idea, and why context matters.
3/ What a prediction cannot tell you
Why a promising idea still needs to be tested in your shop, and why new ideas without a track record deserve room too.
4/ Which ideas to leave out
How rejecting weak hypotheses before development helps you focus your resources on more promising tests.
5/ How Apex puts it into practice
Test memory, a testing tool, and managed execution with the DRIP team. Predictions checked against real results.
We built one of the largest A/B test databases in e-commerce: 4.3 million tests from 151,000 shops, since 2011.
On top of it we built our own testing tool, Apex by DRIP.
Apex tells you which test wins before you build it, and runs your whole testing program in one place.
That prediction helps you prioritise. The experiment still has to prove the result in your shop.
Use the whitepaper to understand the approach and make better decisions about your next tests.
