Length Matters

Test short, punchy descriptions against longer, more detailed ones.

Why it matters:

Some audiences prefer concise info for faster decisions; others want in-depth details before committing to a purchase — especially for higher-priced products.

Pro Tip!

If your products are technical or premium-priced, longer copy often wins — but keep paragraphs short and scannable for mobile shoppers.

Example Setup:

Test Group	Description Length	Example
Control Group	Short	“Minimalist backpack made for daily use.”
Test A	Medium	“A sleek, durable backpack built for work, travel, and everyday use — crafted from recycled materials.”
Test B	Long	“Our minimalist backpack combines timeless design with modern function. Made from recycled fabrics, it includes a padded laptop sleeve, water-resistant coating, and smart internal compartments for daily use or travel.”

Example Insight

A travel accessories brand saw a 14% lift in add-to-cart rate with medium-length copy — enough detail to build confidence without overwhelming readers.
