Sticky add-to-cart. What brands are testing.

What it is

On a phone, the add-to-cart button scrolls out of view as soon as the shopper starts reading the details, the reviews or the photos further down. A sticky bar keeps it in reach: a strip pinned to the bottom of the screen, sometimes with the product photo, name and price beside the button.

Every experiment in this group sits on the product page, mostly at the bottom of the screen on mobile. What brands test is whether to have the bar, what it holds, and how it looks and reads.

What brands tried

The experiments in the record fall into a few themes, all seen between June and October 2026. No brand is named in this section.

Adding a bar. Most added a sticky bar or a pinned button where the page had none, usually on mobile.

What the bar holds. Several tested its contents: photo, name and price against the button alone; a slimmer bar with the price taken out; or the price and a promotion moved into it.

Taking it away. A couple went the other way and removed the sticky bar in favour of the button in the page.

Look and wording. A couple tested how the bar looks or reads — a dark full-width price bar against a light strip with an inset button, or “Select size & add to bag” shortened to “Add to bag”.

What this page does not tell you

• Whether it works. There are no outcome rates here. Outcomes — whether each brand kept the change — are tracked per experiment and are part of the Intelligence plan.
• Whether it will work for you. Your shoppers, prices and range differ from the brands in the record. A change one brand kept can fail on another site.
• Why a brand decided. One experiment is one brand's decision. The record shows what the brand did next, not the measured lift behind it.

ABSee is experimentation intelligence for ecommerce: a record of real experiments run by 1,150+ brands, with the page before, the version tested, and whether it was kept. How the record is built.

How to use this

Treat this page as evidence for a hypothesis, not an answer.

• Bring it to your own hypothesis. Name the problem on your own product page that this change would address, and for which shoppers.
• Check the record for your category. Look for brands like yours, the version they tested, and what they did next.
• Test it yourself. Your own experiment is the only result that applies to your site.
