Add-to-Cart Button Placement Test

Small UI shifts can make massive conversion differences.
Testing where your CTA lives — above the fold, fixed while scrolling, or at the bottom of the page — can reveal how customers interact with your buying funnel.

Example Setup:

Test Group	CTA Placement	Example Description
Control	Below Price	Standard placement under variants
Test A	Floating	Always visible “Add to Cart” button
Test B	Top Section	CTA moved above product title or price

Example Insight

A skincare brand found that a Floating CTA improved add-to-cart clicks by 22% and checkout initiations by 17%, proving constant visibility outperforms static placement.

Pro Tip!

Pair this test with scroll analytics — if most users never reach your CTA, you have a placement problem, not a product one.
