The Mozack Advantage

Meet Customers Where They Already Buy

Marketplace selling isn't just about listing products — it's about visibility, conversion and operational efficiency across every channel. We bring together listing strategy, ad spend management and storefront engineering so your brand shows up consistently wherever customers are shopping.

From Amazon A+ content and eBay category positioning to Walmart item setup and Shopify theme development, every deliverable is designed around the buyer journey in that specific marketplace. We test, measure and iterate — so listings keep performing as competition grows.

Ongoing reporting and account health checks keep your storefronts compliant and profitable. And because our design and development team is in-house, your marketplace visuals and product pages stay aligned with your broader brand.

Full-Funnel E-Commerce

From Listing to Repeat Purchase

We treat every marketplace as a full funnel — from how a product first appears in a search result, to how the product page converts, to how a buyer comes back for the next order. Listing copy, imagery, ads and post-purchase experience are designed as one system.

Our team manages everything from category research and competitor mapping to keyword targeting, A/B testing and review management. Every campaign is reviewed against a clear set of KPIs: impressions, click-through rate, conversion rate and true cost per acquisition.

Where it helps growth, we connect marketplace data back into your broader digital marketing — so paid search, social and email campaigns reinforce the same product positioning customers see on-marketplace.

Industry-Standard Tools

Powered by the Best Platforms

We work directly inside the platforms your customers buy from — Amazon Seller Central, eBay Seller Hub, Walmart Seller Center and Shopify. Every campaign runs on real marketplace data, not assumptions.

For research we rely on Helium 10 and Jungle Scout; for retention we build with Klaviyo; and every marketplace connects back into Google Analytics 4 so performance is measured end-to-end — from first impression to repeat order.

Our design and development team builds the storefronts, product pages and landing experiences that tie the whole system together.

Frequently Asked Questions

We currently manage Amazon, eBay, Walmart and Shopify. Each channel has its own specialist team — from Amazon listing optimization and PPC to eBay store design, Walmart item setup and Shopify theme development. If you sell on multiple channels, we help coordinate them under one strategy.

Timelines vary by channel. Amazon and Walmart usually take 2–4 weeks for account setup, brand registry and initial listings. eBay is often faster at 1–2 weeks. A full custom Shopify build runs 4–6 weeks depending on catalogue size and design scope.
