Listing: Customer Star Ratings

Hypothesis

If we implement 'Customer Star Ratings' on listing pages (This experiment tested the presence of customer review (in the variation)), then key conversion metrics will improve.

Test Results

379,243
Sample size

Key Learning

Context: Users on the listing need validation from others before committing — without visible proof of success, they hesitate.

What was tested: REAL-WORLD TEST: 'Customer Star Ratings' was tested on a live listing page. The test involved 379,243 real visitors. Full statistical results require paid access. Test methodology: This experiment tested the presence of customer review (in the variation). As a result of adding customer reviews, the product page density decreased ...

Result: No statistically significant difference was detected. Inconclusive social proof tests often mean the proof type or placement didn't match what users need at that moment. Try a different format or position.

How to Apply This to Your Site

This experiment tested listing: customer star ratings but produced no statistically significant change. The test was run on a category 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 social proof 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

This experiment tested the presence of customer review (in the variation). As a result of adding customer reviews, the product page density decreased (requiring a bit more scrolling from longer product tiles). Impact on conversion was measured. Also the test originally ran as a "removal of customer reviews" test. However it was flipped here to align with the pattern.
