Removing early buy buttons and sticky bar: +6% conversion rate
Test run byBlend CommerceCRO agency
Commentary byLiftArchiveOur analysis, not theirsRemoving the sticky add-to-cart bar and early shopping buttons, so the only purchase action came after the product education, lifted conversion rate by 6% for Dr Pooper.
Blend Commerce ran the test in Intelligems on the Drain Field Cleaner product page.
It reached only 76% statistical significance, well short of the usual 95%.
- Conversion rate: +6%. Revenue per visitor: +5%.
- Subscription orders per visitor: +33%, and subscription revenue per visitor: +24%.
- Add-to-cart rate: +2%, checkout-begin rate: +4%.
- Desktop moved most, with conversion rate +19% and revenue per visitor +31%. Mobile conversion rate rose 4%.
- All of this sits at 76% significance, so it is encouraging but not proven.
The change
Sticky bar and early buy buttons removed; one purchase action at the end
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The newly redesigned product page had a sticky price and add-to-cart bar on mobile, plus shopping buttons near the top and middle. Shoppers could buy before reading how the product works.
Variant
The sticky bar and all early shopping buttons were removed, leaving a single purchase action at the bottom. Informational links such as 'How It Works' stayed.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Septic treatment is a product people need explained. Earlier tests for this client suggested shoppers converted better after reading more before seeing a price.
- Taking away shortcuts may keep people reading until they understand the value, so they arrive at the buy button more convinced.
- A more informed buyer may be more willing to commit to a subscription, which fits the 33% subscription lift.
Caveats: The result reached only 76% statistical significance, so it could be noise. Duration and sample size were not shared.

How to run this test on your store
- Hypothesis
- If we remove sticky and early purchase buttons so the only buy action comes after the product education, then conversion will rise because shoppers decide with a full understanding of the product.
- Primary metric
- Conversion rate
- Guardrails
- Scroll depth to the purchase section
- Revenue per visitor
- Mobile conversion rate
- Who should test it
- Brands selling unfamiliar or technical products that need explaining before people buy. For simple, well-known products, or repeat buyers who already know what they want, removing quick buy buttons will likely hurt.
Questions
Does a sticky add-to-cart bar always help?
Not always. For Dr Pooper, removing it along with other early buttons raised conversion 6%, though confidence was low.
When should the price appear on a product page?
For products that need explaining, showing price after the education may help.
For familiar products, shoppers usually expect it near the top.
What does 76% statistical significance mean?
It means there is still a fair chance the difference is random.
Most teams wait for 95% before calling a winner.
