Perry Ellis lifts conversion 25% in two weeks with AI review summaries
Apparel brand Perry Ellis saw a 25% conversion-rate increase (1.1% to 1.4%) and a 12% rise in revenue per session within two weeks of piloting Yotpo's AI Review Summary, then rolled it out brand-wide. Amazon and Tripadvisor deploy similar AI review summarization at scale.
Background
Shoppers face long, unstructured review sections that slow purchase decisions on questions like fit, comfort, and quality. AI review summarization condenses many reviews into scannable highlights, helping shoppers decide faster and reducing the effort of reading individual reviews.
What Was Implemented
- Amazon: generative-AI "Customers say" summaries built only from verified-purchase reviews, with attribute-based review surfacing; launched Aug 14, 2023 to a subset of U.S. mobile shoppers.
- Perry Ellis: piloted Yotpo's AI Review Summary on select products on perryellis.com; ran a two-week A/B test on conversion and revenue per session; expanded brand-wide across DTC sites after positive results.
Results
Perry Ellis recorded a 25% increase in conversion rate (1.1%→1.4%) and a 12% increase in revenue per session within two weeks , despite a 13% lower AOV, then rolled the feature out across all DTC brands. Amazon deployed AI review summaries at scale across a broad product selection. Book-cited aggregates: ~ 3% conversion lift from AI review summaries, up to 8% sales lift from AI "smart sorting," and McKinsey's 5–15% conversion lift from personalization (not independently verified here).
Lessons
- AI review summaries can produce measurable conversion gains quickly (within two weeks) on a controlled A/B test.
- Conversion and revenue-per-session can rise even when AOV dips — watch the full funnel, not one metric.
- A successful pilot on select products is a low-risk path to brand-wide rollout.
- Summaries built only on verified reviews (Amazon) preserve trust at scale.
