# Inline 'More details' box on a card application: +15.5% applications

- Outcome: Won
- Page type: Lead form (Lead-gen)
- Elements: Value proposition, Content disclosure
- Test run by: [Tinkoff Bank](https://liftarchive.com/practitioners/tinkoff-bank/)

A 'More details' link that opened an inline box of credit card benefits lifted Tinkoff Bank's submitted applications by 15.5%. A second version, where the same link went to a separate page, did worse than the original. Tinkoff Bank's own analytics team ran the test on over 60,000 visitors across 13 days, and it was published as a VWO case study.

## Result

**+15.5% applications**

- Inline box variant: conversion rate up 15.5%, and it beat control throughout the test.
- Separate-page variant: converted worse than control (exact figure not shared).
- Conversions were submitted credit card applications.
- Over 60,000 visitors across 13 days.

## Control

A credit card application page with a 'Fill out form' button above the fold and a multistep form.

## Variant

A 'More details' link under the button that expanded a box right on the page, listing benefits such as free card delivery, free top-ups and cashback. A second variant sent the link to a separate page instead.

## Why it likely won (our reading)

- The inline box gave key reasons to apply without taking visitors off the form.
- Benefits like free delivery were on the original page but easy to miss; the box made them visible.
- Sending people to another page likely pulled some away from the form for good.

## Caveats

The test ran for 13 days on over 60,000 visitors. Confidence levels for this test were not shared, and the page is from a bank, not a software product.

## How to run this test

- Hypothesis: If we let visitors expand key product benefits inline next to the application button, then more will submit the form because they get reassurance without leaving the page.
- Primary metric: Submitted application rate
- Guardrail: Application approval rate
- Guardrail: Bounce rate
- Guardrail: Clicks away from the form page
- Who should test it: Lead-gen and financial services businesses with a long application form where people want reassurance before starting. Avoid sending that information to a separate page, which lost here.
