A/B testing & experimentation

Test with rigour, promote with confidence

Guesswork dressed as testing wastes spend. CRAFTSGRO sets up clean test cells, tracks statistical confidence as results arrive, promotes the winner when the evidence is there, and folds what it learns back into the next round of creative.

How it works

How an experiment runs

A test is only useful if it is clean, tracked honestly, and acted on. Each step is built to keep it that way.

1

Create test cells

Variants are split into clean cells with comparable audiences, so the difference you measure is the creative and not the setup.

2

Hold conditions steady

Spend and targeting are kept even across cells while the test runs, so one variant does not win simply because it was fed more.

3

Track confidence

Statistical confidence is tracked as data accrues, so you know when a lead is real and when it is still noise.

4

Promote the winner

Once a variant clears the confidence threshold, it is promoted and budget consolidates behind it, ending the test cleanly.

5

Retire the losers

Underperforming cells are wound down rather than left quietly bleeding spend after the question has been answered.

6

Feed creative generation

The winning angle informs the next round of drafts, so each experiment makes the following creative smarter, not just the current campaign.

Worked example

Three variants, one clear winner

A headline test runs three cells against a control. Confidence climbs on one variant while another stays noisy, and the system acts accordingly.
