Removing a sticky navigation bar lifted conversion rate by 1.59% and revenue per visitor by 3.45%. Vasta ran this test for Canada Welding Supply, an industrial equipment store, and published it as a Vasta case study. Pricing, images and copy stayed the same.

## Result

**+1.59% conversion rate**

- Conversion rate: +1.59%, about 31 extra orders a month by the agency's figures.
- Revenue per visitor: +3.45%.
- Average order value: +1.83%.
- Vasta projects about $26,896 in extra monthly revenue. This is the agency's projection.

## Control

A navigation bar that stayed fixed at the top of the screen as shoppers scrolled.

## Variant

The same pages with the sticky navigation removed, so the bar scrolled away like the rest of the page.

## Why it likely won (our reading)

- A fixed bar takes up screen space on mobile, crowding product images.
- On mobile, the sticky bar was taking taps meant for product cards underneath, according to heatmaps.
- Visitors who need the menu can still scroll up to find it.

## Caveats

The test ran 50/50 for 14 days and the agency says it reached statistical confidence, but sample size and the exact confidence level were not shared. The lifts are small, and the monthly figure is a projection.

## How to run this test

- Hypothesis: If we remove our sticky navigation bar, then conversion rate will rise because shoppers see more of the product and make fewer accidental taps on mobile.
- Primary metric: Conversion rate
- Guardrail: Pages per session
- Guardrail: Search usage rate
- Guardrail: Revenue per visitor
- Who should test it: Stores with a tall sticky header that covers a lot of the mobile screen. If shoppers rely on the menu to move between many categories, a smaller sticky bar may be safer than removing it.
