Product Comparison

Overview

Build a side-by-side product comparison feature where shoppers select 2–4 products and see their attributes in a sticky-header table. Attribute rows that are identical across all selected products can be hidden to reduce noise. The comparison state is stored in the URL so it can be shared or bookmarked.

When to Use This Skill

• When selling products with many technical specifications (electronics, appliances, cameras)
• When conversion research shows shoppers are considering multiple products before purchasing
• When the product catalog has well-structured attribute data that lends itself to comparison
• When building a B2B store where buyers need to justify purchase decisions to stakeholders
• When implementing a "Compare" checkbox on product listing pages
