Our Framework

Marketplace growth requires structure before scale.

A four-phase framework designed specifically for multi-SKU craft catalogs. Built for long-term performance, not short-term gains.

The Process

Four phases. One direction.

Every engagement follows the same disciplined path — from margin audit to sequenced multi-channel expansion.

01

Audit & Margin Stability

SKU ValidationMargin AnalysisChannel Audit
  • SKU-level margin validation
  • Competitive saturation analysis
  • Long-term price stability assessment
  • Channel conflict review

We do not scale structurally vulnerable SKUs.

02

Structured Catalog Build

Listing ArchitectureA+ ContentBrand Store
  • Keyword-aligned listing architecture
  • Variation optimization
  • Image & A+ restructuring
  • Brand Store build
  • Cross-SKU cohesion

Built for catalog depth, not isolated products.

03

Controlled Activation

PPCTACoS DisciplineBid Management
  • Selective high-intent PPC
  • TACoS (Total Advertising Cost of Sale) discipline over time
  • Margin-protected bid discipline

Advertising amplifies strong infrastructure.

04

Sequenced Expansion

WalmartMichaelsRetail+
  • Structured Walmart launch
  • Michaels marketplace integration
  • Additional retail marketplaces where aligned
  • Inventory and pricing governance

Expansion follows stability.

Commerce Ecosystem

Marketplace infrastructure is strongest when supported by aligned brand-controlled commerce environments.

We build the full ecosystem — not just the marketplace listings.
