OptiCat vs. SEMA Data: Which Feed Do I Need (and When)?

Introduction

Suppliers often ask: “Do I need OptiCat or SEMA Data?” The truth is — most need both. But each serves a slightly different role in the aftermarket data ecosystem.

OptiCat

• Widely adopted by large retailers and distributors
• Monthly or on-demand feeds
• Strong validation layer — catches ACES/PIES compliance issues early
• Direct ties to e-commerce listings

SEMA Data Co-op

• Broad community of aftermarket brands and resellers
• Supports smaller distributors, niche e-commerce, and specialty categories
• Easier onboarding for suppliers new to data standards
• Includes marketing copy and enhanced product content

Which One First?

• If your main customers are big retailers → start with OptiCat
• If you sell into niche markets or specialty performance → prioritize SEMA Data
• If you serve both → synchronize feeds so they match

Key Tip: The worst mistake is sending slightly different data to each channel. Consistency protects your brand.
