Launch a sticky add-to-cart with delivery reassurance
Reduce hesitation on mobile product pages and improve the rate at which engaged visitors add products to cart.
Hypothesis
If Aster Lane keeps the CTA visible and pairs it with concise delivery and return reassurance, more mobile shoppers will feel ready to take the next step before losing momentum.
To Do List
Design a sticky mobile add-to-cart bar with shipping and return cues.

Experiment launch plan and variant scope
Metrics to Measure
Mobile add-to-cart rate
This captures the earliest behavior the experience is meant to change.
CTA interaction depth
It helps confirm whether the new action pattern is being seen and used.
Add-to-cart signal in 1 to 2 weeks, purchase signal in 3 to 4 weeks
Success criteria
- Mobile add-to-cart rate improves without harming average order value.
- The variant increases purchase conversion on the tested PDP cluster.
- Support-related hesitation events decrease during the test window.
Kill criteria
- Sticky treatment increases interaction but not real purchase intent.
- The bar distracts from core product information and harms engagement.
- Implementation complexity outweighs the lift on lower-traffic pages.
