Budget requirements vary by industry, funnel and competitive intensity, but many advertisers need several thousand dollars per month to collect statistically useful conversion data; smaller budgets can still work if campaigns are tightly targeted to high-intent keywords or remarketing audiences. Prebo Digital designs spend strategies to prioritise profitable channels and scale when unit economics support it.
For eCommerce campaigns the focus is typically on Shopping, dynamic remarketing and ROAS-driven bidding tied to LTV, while B2B emphasises lead quality, account-based targeting, longer attribution windows and CPL/CPA optimisation. In both cases measurement, funnel optimisation and cross-channel attribution are prioritised to ensure spend drives revenue, not just clicks.
Prebo Digital implements clean data pipelines using GA4, Google Tag Manager, and server-side tracking, and ties platform data to on-site conversions and offline events where applicable to reduce attribution bias. Multi-touch attribution models and consolidated reporting are used to align spend with revenue and lifetime value rather than platform-reported last-click metrics.
Prebo Digital offers end-to-end Google Ads services including account audits, campaign strategy and setup (Search, Shopping, Display, Video, Remarketing), bid and budget management, conversion tracking implementation, and ongoing performance optimisations focused on revenue outcomes.
Time to profitability depends on product margins, funnel conversion rates, tracking accuracy and budget; an initial data-collection and learning phase commonly takes 4-8 weeks, with structured optimisation and scaling typically assessed over several months. Prebo Digital focuses on iterative testing and measurement to improve profitability rather than short-term traffic metrics.

Revenue-First Outcomes
Typical Timeline
A PPC audit is a structured review of a pay-per-click account that evaluates strategy, account structure, tracking integrity, creative performance, and cost-efficiency. For US-based brands and Shopify stores, the audit focuses on revenue impact (CAC, LTV, and MER), not just clicks or impressions. In short, a PPC audit identifies revenue leakage, mismatches between platform reporting and your revenue data, and practical fixes to improve profitability.
Run an audit when: performance stalls for 4-8 weeks, CAC drifts above target, tracking changes (e.g., GA4 migrations), or before scaling budgets. A quarterly audit is common for growth-stage stores while early-stage brands often need audits after major site changes or platform transitions.
If you want a practical overview of how we structure recurring performance work, see our Services overview which outlines strategy → build → test → scale workflows.
Pro tip: reconciling platform-reported conversions to your order pipeline (Stripe/Shopify/HubSpot) reduces noise. Even small differences (5-15%) can distort CAC and scaling decisions.

| Signal | Role in reconciliation |
|---|---|
| Client-side pixel (Meta/GA4) | Captures user events but can be blocked or dropped by browsers |
| Server-side tracking | Provides durable event delivery to ad platforms and reduces loss |
| Order system (Shopify/Stripe) | Source of truth for revenue reconciliation and LTV calculations |
A baseline audit typically takes 7-14 business days for a single account, depending on account complexity and data access. Comprehensive audits that include server-side tracking and revenue reconciliation can take 3-6 weeks to scope, implement fixes, and validate results in the United States market context.
Recommendations focus on profitability. An audit might suggest reallocating budget away from low-margin campaigns or pausing problematic tracking-dependent campaigns until reconciliation is fixed. The goal is to protect CAC and MER while enabling safe scale.
Audits compare platform-attributed conversions (last-click, data-driven) against first-party revenue and recommend an attribution framework that aligns with your business model and reporting cadence. For ecommerce stores on Shopify, that often means prioritizing order-level revenue and testing blended models for lifetime value estimates.
Example: a US Shopify store reports $50,000 in platform-attributed conversions for a 30-day window, but first-party order data shows $42,500. That 15% discrepancy can overstate ROAS and lead to overspending when scaling. Estimated reconciliation work may cost between $2,000-$6,000 depending on server-side setup and eCommerce complexity.
| Stage | Primary questions |
|---|---|
| TOF (Top of Funnel) | Are audiences and creatives driving qualified traffic? |
| MOF (Middle of Funnel) | Is messaging and retargeting converting at acceptable rates? |
| BOF (Bottom of Funnel) | Are checkout flows and attribution aligning with revenue goals? |
If you manage multiple channels, coordinate audits across Google Ads, Meta, and other platforms to avoid siloed recommendations. Our approach treats data pipelines and attribution as the baseline for all channel decisions - see how this integrates with cross-discipline services in our homepage.
An effective audit culminates in prioritized fixes and measurable KPIs: reduced untracked conversions, clearer CAC by channel, and a tested rollout plan for scaling. For growth teams, that means cleaner reporting to inform monthly budget decisions and long-term LTV modeling.
