Product: Field Explanations on Product Page
Hypothesis
If we add field explanation tooltips to form fields on product detail pages, then form completion and conversion rates will improve because users better understand what information is required and why
Test Results
Key Learning
Context: Each additional form field adds friction to the product, increasing the chance users abandon before completing their submission.
What was tested: Form field explanations reduce completion errors and abandonment by clarifying what information is needed and why; most impactful for non-obvious fields like VAT numbers or ID formats
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 product: field explanations on product page but produced no statistically significant change. The test was run on a product page page in the cross-industry industry. Inconclusive results suggest this particular change may not be a priority — focus testing effort on higher-impact areas.
Before you test: Consider that form tests typically require large sample sizes to detect small effects. Run your test for at least 2 full business cycles to account for weekly traffic patterns.
What Was Tested
In this product detail page experiment, the variation showed a tooltip icon. Upon hovering on the icon it expanded additional information explaining the difference between pay in full and pay per shipment. Impact on sales was measured.
