Get clear answers to frequently-asked-questions-about-ppc-audits: scope, timeline, tracking issues, and how audits improve CAC and revenue accuracy.
Structure, tracking integrity, attribution, creative, and funnel conversion.
Prioritized fixes tied to CAC, MER, and first-party revenue reconciliation.
Baseline audit: 7-14 business days; full reconciliation: up to 6 weeks.
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.
