# Product Page Design SOP - Industry Best Practices
|
|
|
|
**Document Version:** 1.0
|
|
**Last Updated:** November 26, 2025
|
|
**Purpose:** Guide for building industry-standard product pages in Customer SPA
|
|
|
|
---
|
|
|
|
## 📋 Executive Summary
|
|
|
|
This SOP consolidates research-backed best practices for e-commerce product pages based on Baymard Institute's 2025 UX research and industry standards. Since Customer SPA is not fully customizable by end-users, we must implement the best practices as defaults.
|
|
|
|
---
|
|
|
|
## 🎯 Core Principles
|
|
|
|
1. **Avoid Horizontal Tabs** - 27% of users overlook horizontal tabs entirely
|
|
2. **Vertical Collapsed Sections** - Only 8% overlook content (vs 27% for tabs)
|
|
3. **Images Are Critical** - After images, reviews are the most important content
|
|
4. **Trust & Social Proof** - Essential for conversion
|
|
5. **Mobile-First** - But optimize desktop experience separately
|
|
|
