Accordion vs slider on the product page: +5.8% revenue per visitor
Commentary byLiftArchiveOur analysis, not theirsFishwife tested an accordion against a slider for its product page content, and the version it shipped lifted revenue per visitor by 5.8%.
The tinned fish brand's in-house growth team ran the test, and it was published as a Shoplift case study.
The source does not say which layout won.
- Revenue per visitor: +5.8% for the version Fishwife shipped.
- One version had stronger engagement but weaker revenue. The team chose on revenue, not clicks.
- Sample size, duration and confidence were not shared.
Control
Product page content shown in one format, either an accordion or a slider. The source does not say which was the original.
Variant
The same content shown in the other format.
Why it likely won
Our reading of the result, not the practitioner's claim.
- More interaction with page content does not always lead to more sales. Shoppers may click around without moving closer to buying.
- How content is packed on a product page changes what shoppers see first and how far they scroll to the add-to-cart button.
- Fishwife judged tests on revenue per visitor, which catches cases where engagement and sales move in different directions.
Caveats: The source does not say whether the accordion or the slider won, and gives no sample size, duration or confidence level. It is a testing-tool vendor's case study.

How to run this test on your store
- Hypothesis
- If we change how product page content is presented (accordion vs slider), then revenue per visitor will change because the format affects what shoppers read and how quickly they reach the buy button.
- Primary metric
- Revenue per visitor
- Guardrails
- Add-to-cart rate
- Engagement with the content block
- Mobile conversion rate
- Who should test it
- Stores with a lot of product page content, such as recipes, ingredients or how-to guides, that needs to be packed into a small space. It is unlikely to matter much on short, simple product pages.
Questions
Is an accordion or a slider better on a product page?
There is no single answer. Fishwife found a 5.8% revenue difference between the two but did not say which won, so test both with your own content.
Should I pick the variant with more engagement?
Not on its own. In this test, the version with stronger engagement brought in less revenue.
