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.

Structured roadmap
If you sell on Amazon, eBay, Walmart, or other online marketplaces, optimization is less about traffic and more about profitable conversions. Marketplaces require specialized product feeds, listing architecture, PPC strategies, and cross-channel attribution to move customers through the funnel and protect margins. This guide shows how to choose an online marketplace optimization service by focusing on revenue impact, attribution accuracy, and long-term scalability.
Start by translating business goals into measurable outcomes. Common objectives include lowering cost-per-acquisition (CPA), increasing buy box share, improving organic marketplace rank, and raising average order value (AOV). For US-based examples, target metrics might be reducing CPA from $45 to $30 or increasing AOV from $55 to $72 - these are illustrative estimates and will vary by category and channel.
A technical-first provider will combine these capabilities with automation and data pipelines rather than isolated, tactical fixes. If you want a succinct overview of the types of services agencies offer, review the agency's service scope like a centralized list on their services page: Prebo Digital services.
Prefer providers with demonstrable experience in your marketplace and category. Breadth matters (Amazon, Walmart, eBay, and regional marketplaces), but so does depth - look for case studies that show improved profitability, not just traffic. For a sense of the agency's approach and team, check the agency background: About Prebo Digital.
A vendor that focuses on clean data pipelines and attribution will discuss GA4, server-side tracking, or an ETL that moves purchase-level data into a unified warehouse.

| Funnel Stage | Data Point | Recommended Tracking |
|---|---|---|
| TOF (awareness) | Impressions, clicks | Platform ad APIs + click IDs |
| MOF (consideration) | Detail page views, adds to cart | Server-side events + session stitching |
| BOF (conversion) | Orders, revenue, returns | Order-level ingestion to GA4/warehouse |
Note: US sellers should prioritize server-side tracking where marketplaces allow order-level exports. This reduces attribution loss from browser restrictions and consent friction.
Proposals typically fall into three pricing models: flat monthly retainers, percent-of-ad-spend, or blended hybrid retainers. For scalability and alignment to revenue, many growth-focused teams prefer retainers that include performance-based milestones tied to MER (marketing efficiency ratio) rather than vanity metrics. Ask vendors to model a 6-12 month plan showing expected CPA, incremental revenue, and assumptions (for example, a $50k monthly ad spend and target MER improvement from 40% to 30% - hypothetical figures for planning).
A capable vendor will map integrations before kickoff: marketplace APIs, payment processors (Stripe/Shopify Payments), email platforms (Klaviyo), and your analytics stack (GA4, server container, data warehouse). Ask for an integrations diagram and a timeline for data ingestion. Vendors with engineering resources can build ETL connectors to normalize SKU-level data and feed it into your analytics layer.
Look for specific test plans that cover TOF→MOF→BOF. Example tests might include updated product titles and images (organic lift), campaign restructure into audience-focused segments (PPC efficiency), and a checkout experience audit to reduce friction. A structured framework is better than ad-hoc tactics - ask vendors to show a Strategy → Build → Test → Scale → Report roadmap with monthly deliverables.
Vendors should document how they handle each pitfall and provide an incident playbook. If you want to discuss marketplace growth with a team that emphasizes attribution and profitability, consider scheduling a discovery to compare frameworks and technical readiness: Talk to a Prebo Digital rep.
A final validation step: request a reference call with a current client in a similar US category and ask about reporting clarity, cadence, and realized margin improvements. For more on how performance-driven agencies organize work and reporting, see the agency services overview: Prebo Digital services.
If you manage a Shopify or WooCommerce storefront in parallel with marketplaces, ensure the vendor can reconcile orders and returns across channels. Example: reconciling a $120 order from Amazon with a returned item should correctly adjust LTV and CAC in your warehouse. These practical reconciliations are a common deliverable in structured retainers.
