A sticky CTA is a call-to-action element that remains visible on the screen while the user scrolls. It ensures the action button is always accessible, reducing friction in the buying process.
Why Sticky CTA matters?
On mobile devices, long product pages can push the add-to-cart button far out of view. If customers must scroll back up to take action, some will abandon the purchase. A sticky CTA keeps the key action present at all times, which can improve conversion rates and reduce drop-offs.
How Sticky CTA works?
Sticky CTAs are typically implemented as fixed-position bars or buttons anchored to the top or bottom of the screen. They often include essential details such as the product name, price, and action button. Proper design ensures they are unobtrusive yet clearly visible.
Example in ecommerce
A shoe retailer adds a sticky "Add to Cart" button on mobile product pages. Add-to-cart rates increase by 12 percent, particularly among mobile visitors who no longer have to scroll back up.
Common mix-ups
A sticky CTA is not the same as a floating action button for utility actions like live chat. Sticky CTAs are tied directly to the purchase or conversion goal.
Best practices
- Keep the design minimal but eye-catching.
- Ensure it does not cover important content.
- Include key purchase details where relevant.
- Optimize for both mobile and desktop users.
- Test the impact on user behavior and conversion rates.
Industry benchmarks
- Sticky CTAs on mobile PDPs can raise add-to-cart rates by 8 to 20 percent in testing.
