Yes - Prebo Digital uses GA4, Google Tag Manager, server-side tracking, and ETL to ingest Amazon order and ad data into analytics and BI systems, enabling consolidated attribution and cross-channel measurement. This supports more accurate channel comparisons and decisioning.
The right choice depends on margin structure, CAC, LTV and customer lifecycle: Amazon is effective for demand capture and scale, while an owned store is better for customer lifetime value and margin retention. We recommend evaluating profitability per channel and implementing systems to migrate repeat buyers to owned channels where feasible.
Scaling is done through a structured framework: granular campaign segmentation, controlled budget tests, ROAS and CAC thresholds, listing optimisation, negative keyword management, and automation-supported bidding rules. Each step is validated with clean attribution to ensure growth aligns with profitability targets.
Prebo Digital reconciles Amazon ad reports with first-party order and backend data using server-side tracking and ETL pipelines to produce accurate ROAS, CAC, and MER. This measurement prioritises revenue and profitability metrics over platform-reported conversions.
Conversion optimisation focuses on data-driven changes to images, titles, bullet points, A+ content, pricing tests, review management, and backend search terms, coupled with incremental experiments. Impacts are measured using order-level attribution and experiment results rather than surface metrics alone.

Scale with Systems
Optimizing for online marketplaces (Amazon, Walmart, eBay, Etsy and others) is less about chasing clicks and more about increasing measurable revenue and lowering net customer acquisition cost (CAC). Marketplace search engines reward relevance, conversion history, and accurate attribution. This guide covers structural listing improvements, conversion tracking, funnel optimization (TOF → MOF → BOF), and US-specific compliance considerations to help brands convert marketplace traffic into profitable customers.
A listing is a micro landing page. Treat it like one. Review these elements with measurable goals (CTR, add-to-cart rate, and purchase conversion rate):
Marketplace ranking algorithms prioritize conversion signals (rate, velocity, returns) over backlinks. That means optimization work must include both content and conversion-rate tactics. Use on-platform analytics and supplement with server-side tracking to attribute sales back to paid channels and off-platform campaigns.
Note: focus on lifetime value (LTV) and profitability, not vanity metrics like impressions. Use MER and margin-aware ROAS to evaluate paid marketplace spend.
Marketplace platforms often limit client-side tracking and redirect flows. Implementing server-side tracking and tying marketplace events into GA4 (via a server endpoint or measurement protocol) reduces attribution loss and improves decision-making. Below is a simple conversion tracking diagram showing the flow from ad click to revenue sync.
User clicks marketplace ad → Marketplace click redirect → Listing page view → Add to cart → Purchase → Marketplace order confirmation → Server-to-server revenue event → GA4 / Analytics & internal ETL
For step-by-step implementations and platform-specific integrations, pair marketplace instrumentation with your storefront analytics. If your primary storefront is Shopify, ensure your orders and marketplace sales are reconciled in a single data pipeline to calculate accurate CAC and MER.

Below are actionable optimizations that performance teams and founders can implement today, followed by measurement best practices tailored to US sellers.
Use a mix of broad discovery and exact-intent campaigns. Optimize bids for profitable ACoS or MER targets, not just top-of-funnel volume. For US marketplaces, factor in shipping speed and return costs when modeling CAC and customer LTV.
Implement a server-side endpoint to receive order confirmations from marketplaces where possible, then forward revenue events to GA4 and your data warehouse. This reduces cookie loss and improves attribution for ads running across Google, Meta, and marketplace DSPs. Prebo Digital frequently uses a structured framework: Strategy → Build → Test → Scale → Report to keep experiments accountable.
Assume a $50,000/month ad budget across sponsored search and display on a major US marketplace. With an initial MER target of 3.0 and average order value (AOV) of $70, the goal is to drive ~2,143 attributable orders while keeping net margin positive. These are estimates and will vary by category, return rates, and shipping costs. Use server-side reconciliation to validate attributed revenue against marketplace settlement reports.
