Server-side tracking is recommended when you need more reliable event delivery, reduced loss from ad blockers or browser restrictions, and tighter control over data routing and PII. It is typically used alongside client-side tags to improve attribution accuracy and data governance.
Run tag and network debuggers, execute synthetic transactions through the full funnel, reconcile analytics events to backend order and revenue data, and set automated alerts for event drops or source discrepancies. Regular audits of event naming, parameter consistency, and ETL integrity help maintain long-term measurement quality.
We implement consent-aware tag firing, server-side proxies, and cookieless or modeled measurement techniques so key funnel signals are preserved without overriding user choices. All modeled data is labelled in reports to separate observed from inferred metrics.
A typical implementation maps enhanced eCommerce events to a consistent dataLayer, deploys GA4 via Google Tag Manager with optional server-side forwarding, and funnels raw events into BigQuery for attribution, reporting, and downstream ETL. This ensures events are structured for revenue-focused analysis rather than just traffic metrics.
We consolidate events through GA4, server-side tagging, and a central data pipeline (BigQuery/ETL) to reconcile platform conversions with backend revenue. Deterministic identifiers and consistent event schemas reduce discrepancies between platform-reported and first-party data.

Structured retainer model
Transparent pricing guidance
Requesting a quote for digital marketing retainer services should be a structured conversation about measurable outcomes - not a price list. At Prebo Digital we design retainers that prioritise revenue growth, attribution clarity, and sustainable CAC reduction. Use this guide to prepare the data and expectations that lead to a precise, actionable retainer proposal.
Providing these details up front reduces back-and-forth and helps us deliver a retainer quote that aligns fees to expected business impact. If you need a quick reference for Prebo Digital's offerings, see our Services Overview which outlines core deliverables such as Google Ads management, CRO, and analytics-and-tracking.
Prebo Digital structures retainers around a five-stage framework: Strategy → Build → Test → Scale → Report. Each proposal breaks down deliverables by month, expected tests, and attribution improvements so leaders can evaluate ROI against clear benchmarks.
Pro tip: include access to analytics and ad accounts when you request a quote - it lets us validate conversion paths and provide an accurate estimate faster.
Learn more about Prebo Digital's company approach and technical-first methodology on our About page. That context helps set expectations on scope, reporting cadence, and governance for long-term retainers.
A commercial retainer with Prebo Digital commonly includes channel strategy (Google Ads, Meta, programmatic where relevant), conversion rate optimisation (CRO) tests, server-side tracking or GA4 configuration, and monthly performance reporting with attribution modelling. Monthly retainer fees vary by scope; as an example, full-service eCommerce retainers that include persistent CRO and paid media management typically start in the range of $5,000-$15,000 per month, depending on spend level and technical complexity. These figures are estimates and will be refined after an initial audit.
| Included | Excluded (can be added) |
|---|---|
| Monthly strategy, 1-2 CRO experiments, ad creative guidance, server-side tracking setup | Ad creative production, third-party software licenses, paid media budgets |
| GA4 and GTM governance, ETL for reporting, weekly dashboards | Full-time in-house media buying, large-scale UI redesigns |
We link retainer scope to measurable outcomes: CAC reduction, LTV growth, and MER improvement. For instance, a $10,000/month retainer paired with a $50,000 monthly ad spend might aim to lower blended CAC by 10-20% over six months through attribution cleanup, funnel testing, and bid strategy refinement. These are scenario-based estimates for US audiences and assume access to server-side events and order-level data.
