Keeping membership prices pinned to the top of the screen while visitors scrolled the plan comparison lifted overall sign-up conversion by 2%. PureGym's product team ran this test on step two of its online join journey. It was published as an AB Tasty case study, now hosted by Wingify.

## Result

**+2% conversion**

- Overall conversion: +2%. More visitors went on to become members.
- Progression to the next step of the join flow also went up, according to PureGym. No figure was shared for this.
- Sample size, test duration and confidence level were not shared.

## Control

Step two of the join flow showed a comparison table of membership options such as Plus, Core and Off-Peak. As visitors scrolled down to read plan benefits, the prices scrolled out of view, and the monthly fee and one-off joining fee sat in different places.

## Variant

The prices stayed fixed at the top of the screen while visitors scrolled through the plan comparison, so cost was always visible next to the features being read.

## Why it likely won (our reading)

- People comparing plans want to match each feature to a price. When the price vanishes, they have to scroll back up, which adds effort and doubt.
- Two separate fees in two separate places can make the total cost feel unclear. Keeping prices in view may have reduced that confusion.
- PureGym noted the effect matters most on mobile, where a long table pushes the prices off a small screen quickly.

## Caveats

The case study does not share sample size, duration or significance. The 2% figure is company-reported in a vendor case study.

## How to run this test

- Hypothesis: If we keep plan prices pinned to the top of the screen while visitors scroll the plan comparison, then more visitors will pick a plan and continue, because they never lose sight of what each option costs.
- Primary metric: Completed sign-ups (or paid memberships) per visitor reaching the plan comparison step
- Guardrail: Mix of plans chosen (watch for a shift to the cheapest plan)
- Guardrail: Progression to the next step
- Guardrail: Mobile page performance and layout issues
- Who should test it: Membership, subscription and SaaS businesses with a long plan comparison table, especially if most traffic is mobile. If your pricing fits on one screen without scrolling, there is little to gain.
