The Problem: Siloed Platforms, Siloed Intelligence

The Problem

Merchants selling on multiple platforms use a different recommendation tool for each one — or worse, no recommendations at all on secondary channels. Each platform has its own limited data silo, and there's no way to share intelligence across them.

SellerZoom connects to Shopify, Amazon, eBay, WooCommerce, and BigCommerce through native integrations. One recommendation engine powers all your stores, with cross-platform product deduplication, synchronized catalogs, and unified analytics. Purchase signals from your Amazon store improve recommendations on your Shopify store, and vice versa.

Setting It Up: Step by Step

1

Connect Your Primary Store

Start with your highest-traffic platform. For Shopify, use the one-click OAuth install. For WooCommerce, enter your store URL and REST API keys. For Amazon/eBay, follow the marketplace authorization flow in Settings → Connectors.

2

Add Secondary Platforms

Go to Settings → Connectors and click "Add Platform." Connect each additional store. SellerZoom will sync catalogs from all platforms and begin the deduplication process.

3

Review Deduplication

Products that appear on multiple platforms are automatically detected using title/SKU matching and semantic embedding similarity. Review the suggested matches on the Products page — confirm or reject each deduplication pair. This ensures your catalog is unified without duplicate entries.

4

Configure Per-Platform Widgets

Each platform can have its own widget styling and placement. Shopify uses the JS widget embed; WooCommerce uses a plugin; Amazon and eBay use SellerZoom-powered external landing pages that link back to your listings.

5

Unified Dashboard

All analytics — revenue attribution, conversion funnels, recommendation performance — roll up into a single dashboard. Filter by platform to compare performance, or view the combined picture.

Why Unified Intelligence Outperforms Platform Silos

Cross-platform signals are multiplicative. A product that sells well on Amazon (high co-purchase count) gets boosted in your Shopify recommendations too. You're leveraging data from thousands of additional transactions that a single-platform tool would never see.

Deduplication eliminates waste. Without deduplication, the same product on two platforms is treated as two separate products — fragmenting purchase signals and diluting recommendation accuracy. Unified products have complete data, leading to better recommendations everywhere.

One system to manage. Instead of configuring recommendations on Shopify, manually merchandising on Amazon, and ignoring eBay entirely, you configure once in SellerZoom and it propagates everywhere. Changes to signal weights, margin rules, and A/B tests apply across all platforms.

Pro Tip

Connect your highest-volume platform first and let it build a strong co-purchase graph before adding secondary platforms. The secondary platforms will immediately benefit from the primary platform's data rather than starting cold.

Case Study: Multi-Channel Homeware Brand

Case Study

Oaken Goods

Background: Oaken Goods sells handcrafted homeware across Shopify (primary store), Amazon (wholesale), and Etsy/eBay (vintage line). Each platform had its own product listings with different titles, images, and pricing. Recommendations only existed on Shopify.

Implementation: Connected all three platforms, deduped 340 overlapping products, and enabled unified recommendations. Amazon purchase data enriched Shopify recommendations; Shopify's rich product descriptions improved embedding quality for Amazon listings.

Key insight: Amazon's high order volume (5x Shopify) generated massive co-purchase signals that dramatically improved Shopify recommendation quality. Products that appeared "cold" on Shopify (few purchases) had rich behavioral data from Amazon, eliminating the cold-start problem for most of the catalog.

Managing Inventory Across Platforms

One of the biggest challenges for multi-channel merchants is inventory accuracy. SellerZoom syncs inventory status from each platform every 15 minutes (Shopify) or hourly (Amazon, eBay). Products that go out of stock on one platform are automatically excluded from recommendations on that platform, even if they're still in stock elsewhere. This prevents the frustrating experience of recommending unavailable products.

Leveraging Cross-Platform Insights

The unified analytics dashboard reveals patterns invisible to single-platform tools. You might discover that a product category performs well on Amazon but poorly on Shopify — suggesting a merchandising or pricing issue specific to your own store. Or you might find that certain product pairings convert on WooCommerce but not on eBay, indicating audience differences. These cross-platform insights inform not just recommendation strategy, but broader merchandising, pricing, and inventory allocation decisions.
