BliVakker.no removed three fields from the 17-field registration step in its checkout, and form submissions rose 11%. The beauty retailer ran the test itself. The story first appeared on Tribes.no and was later published as a VWO case study.

## Result

**+11% sign-ups**

- Form submissions: +11% for the light version versus the original.
- Ultra-light version: the source says removing too much was not optimal, which suggests it did worse. Its numbers are only shown in an image.
- The team planned to simplify more of the purchase flow based on this result.

## Control

The registration step in the purchase process had 17 form fields.

## Variant

A light version dropped three fields: account number, phone number and evening phone number. A third, ultra-light version cut even more fields and some navigation.

## Why it likely won (our reading)

- Every field is a small task, and fields like an account number feel intrusive at sign-up.
- Asking for two phone numbers adds effort without a clear reason for the shopper.
- Going too far may have removed fields or links that people expected, which made the ultra-light form feel less trustworthy.

## Caveats

No sample size, duration or confidence level was shared, and the detailed numbers appear only in an image. The site had about 20,000 visits a day at the time.

## How to run this test

- Hypothesis: If we remove fields we don't need from our registration form, then more shoppers will complete it because there is less to fill in.
- Primary metric: Registration form submission rate
- Guardrail: Completed orders
- Guardrail: Delivery or contact failures from missing data
- Guardrail: Customer service contacts
- Who should test it: Stores that force account creation or long sign-up forms during checkout. If your form is already short or you offer guest checkout, gains will be smaller.
