Growth.Design opened its case studies in fullscreen, distraction-free mode by default and reported a 280% increase in engagement. Growth.Design ran this as a private experiment in 2020 and mentioned it briefly in its TikTok feed case study. The method, sample and the meaning of engagement were not shared.

## Result

**+280% engagement**

- Engagement with case studies: up 280%, per Growth.Design.
- Engagement is not defined, and no test method or sample was given.
- Treat the size of the number with caution given how little detail is available.

## Control

Case studies opened in the normal page view, with the site's usual navigation around them.

## Variant

Case studies opened in fullscreen mode by default, hiding other parts of the site.

## Why it likely won (our reading)

- Removing navigation and other links leaves fewer reasons to leave the content.
- A fullscreen story format makes each step feel like the whole screen, which may keep people clicking through.
- Growth.Design's slide-based format may suit fullscreen more than a regular article would.

## Caveats

Mentioned in passing as a private 2020 experiment; method, sample and engagement definition are not given. Our database treats it as a before-and-after result.

## How to run this test

- Hypothesis: If we open long-form content in a distraction-free fullscreen view by default, then readers will engage more because there are fewer exits and distractions.
- Primary metric: Content completion rate (share reaching the end)
- Guardrail: Lead or sign-up conversion from content
- Guardrail: Bounce rate
- Guardrail: Navigation to other pages
- Who should test it: Lead-gen and SaaS teams using interactive or step-by-step content to build an audience. For content meant to send readers to other pages, hiding navigation may cost you those clicks.
