# Easiest Field First: Form Field Order A/B Test

Page: https://alidemirbas.com.tr/en/lab/ab-test-library/tests/easiest-field-first-form-field-order-ab-test

## Hypothesis

If the form opens with an easy field such as name or email, visitors take the first step with little effort and may be more willing to finish what they started. Any gain in the form completion rate depends on abandonment not simply moving to the harder fields at the end.

## When to run this test

If the field-level abandonment report shows exits piling up at a difficult question, people pause long at the first field, or past error data clusters at the top of the form, visitors are dropping out early and field order is worth testing. If the new order works, visitors who start with easy fields keep going when they reach the harder ones, and valid submissions go up. If the exits come from one question that visitors do not understand, clarify its wording first. Keep consent text and other fields that must legally appear at a specific point where they are, and reorder only the remaining fields.

## Primary metric

**Form completion rate**: Compare successful submissions to see whether reordering fields affects completion.

## Other metrics

- **Form start rate**: Compare visitors who begin the first field after seeing the form.
- **Field-level abandonment**: Track the field where visitors leave and check that abandonment has not simply moved to the end.
- **Form completion time**: Compare time from form start to successful submission.
- **Valid submission rate**: Measure submissions that meet business rules; check whether faster completion leaves invalid data.

## What to check before and during the test

- **Order**: Compare the current order with a predefined easy-to-difficult order supported by past error or completion-time data.
- **Keep constant**: Keep fields, labels, validation and required status unchanged.
- **Abandonment**: Review all abandonment points, including difficult fields moved to the end.
- **Logical flow**: Preserve field dependencies and a sensible sequence of questions.
- **Segments**: Check whether new and returning visitors respond differently to the order.

## What to watch when reading the result

- A higher form start rate is not a win on its own. Unless the form completion rate and the valid submission rate rise with it, the new order may just be pulling more people into the form and losing them at the end.
- What you learn here describes only the form type you tested. Other forms have different field difficulty and dependencies, so test the order there again before writing it down as a general rule. Read how new and returning visitors respond to the order separately, too.
- Do not decide early just because abandonment looks lower; check field by field whether it has shifted to the difficult fields now at the end. To set the run length up front, divide the per-variant sample from the [sample size calculator](https://alidemirbas.com.tr/en/calculators/sample-size-calculator) by the form visitors each arm gets per day, and if the gap is still small when that period ends, report the result as inconclusive.

## Frequently Asked Questions

### How should easy-to-hard field ordering be chosen?

Use prior error or completion-time evidence while preserving logical dependencies. Do not move consent or disclosure fields contrary to applicable presentation requirements.

### Does a higher form-start rate mean the order worked?

Use valid form completion as the primary outcome. Easier opening questions can move abandonment to later fields rather than reduce it.

### Could faster users submit worse data?

Yes. Monitor submissions that meet the same validity and business rules. Shorter completion time is diagnostic, not a substitute for valid completed forms.
