Multiple: Product Page Redesign and Checkout Optimization for eBay
Hypothesis
eBay's siloed development process resulted in new features being launched without conversion testing. A unified product page template with clearer item presentation, improved alternatives section, and streamlined checkout will increase conversion rates across the marketplace.
Test Results
Key Learning
Context: Mobile users experience the multiple differently — smaller screens, touch targets, and limited attention require purpose-built design.
What was tested: Marketplace platforms without a unified product page standard leave significant conversion on the table. Mobile conversion parity with desktop requires dedicated mobile-first test designs, not desktop adaptations. Suggested alternatives sections can increase or decrease conversion depending on placement and relevance
Result: No statistically significant difference was detected. This null result is still valuable — it narrows the search space and helps calibrate your minimum detectable effect for future tests.
How to Apply This to Your Site
This experiment tested multiple: product page redesign and checkout optimization for ebay but produced no statistically significant change. The test was run on a landing page page in the e-commerce industry. Inconclusive results suggest this particular change may not be a priority — focus testing effort on higher-impact areas.
Before you test: Consider that layout tests typically require adequate traffic to reach statistical significance. Run your test for at least 2 full business cycles to account for weekly traffic patterns.
This result reached 95% statistical confidence, meaning there is a very low probability the observed effect was due to chance. Results at this confidence level are generally considered reliable for making business decisions.
What Was Tested
eBay engaged Invesp to break down silos between development, product, and marketing teams and build an experimentation culture. Invesp conducted comprehensive conversion audits and behavioral research, then focused initial experiments on product pages, suggested alternatives sections, and the checkout process. Mobile conversion rates were a specific focus as mobile traffic dominated but converted far below desktop rates.

Context: Capturing visitor attention on the product with modals or overlays is a balance between engagement and annoyance.
