The Measurement Scan is a preliminary review of what's visible from your public storefront - no account access required. We check how your Meta and Google (or TikTok and Pinterest for example) pixels are firing, whether core events (product view, add to cart, checkout, purchase) are reaching the platforms, whether your consent configuration is contributing to data loss, and whether there are indicators of server-side infrastructure already in place. The scan identifies likely gaps and tells you honestly whether a full audit would be warranted. If there's no meaningful issue, we'll tell you that too.

The audit requires read access to your ad accounts and Shopify store. We review your complete tracking architecture, browser-side and server-side, validate event quality, check for deduplication, assess consent signal handling, and map exactly where conversion data is breaking before it reaches Meta or Google. You receive a structured written report documenting every gap found and our recommended fix for each, plus a 60-minute recorded review call where we walk through the findings and answer your team's questions. The $850 audit fee is credited in full against implementation if signed within 30 days of audit delivery, so if you go ahead, the audit costs you nothing.

Shopify's native integrations (the Meta app, the Google & YouTube app) send basic conversion data through browser-side pixels. The problem is that browser-side tracking fails silently in several common scenarios: Safari restricts cookie lifespans, ad blockers block pixel requests, Shopify's checkout runs inside a sandboxed iframe that limits what client-side code can access, and users who pay with Shop Pay complete checkout on a separate domain entirely. Server-side tracking routes purchase data directly from Shopify's backend to your ad platforms, bypassing those browser restrictions entirely. It's not a replacement for native integrations - it's the infrastructure that ensures your real conversions actually arrive. As of 26 August 2026, Shopify has also sunset Additional Scripts and legacy script tags on the Thank You and Order Status pages for non-Plus stores. The supported replacement, Web Pixels, runs in a sandboxed iframe with no direct DOM access and only scoped, permissioned cookie access. Migrating to it is necessary, but it does not on its own restore what a browser-only setup was losing.

We build on server-side Google Tag Manager, Meta Conversions API, Google Enhanced Conversions and the relevant platform event feeds. Hosting can be managed through a specialist provider, such as Addingwell or Stape, or deployed inside the client’s own Google Cloud project. The audit determines which model fits the client’s volume, governance and technical requirements. For brands with higher event volumes, data residency requirements, procurement constraints, or an existing Google Cloud estate, we deploy directly into your own GCP project on Cloud Run, so the infrastructure and the billing sit inside your organisation. The audit determines which. You are never put on a platform because it happens to be the one we always use.

The free Measurement Scan requires no account access - it's based entirely on what's publicly visible from your storefront. The full Conversion Tracking Audit requires read-level access to your Shopify store and your Meta and Google Ads accounts. We use this access to review event quality and data flow - we don't make changes to your accounts without your explicit approval, and we can work within a scoped access level if your team prefers.

The Conversion Tracking Audit is typically completed within 5-7 business days of receiving account access. Implementation of the full server-side infrastructure takes 2-4 weeks depending on your store's complexity, the number of ad platforms in scope, and any custom event requirements. We work around your team's availability and do not require a development sprint or significant internal resource from your side.

Shopify is where we do most of our work, because the checkout sandbox and the August 2026 migration created the most consistent and most expensive gaps in the market. The measurement problem is not Shopify-specific, though. We work on WooCommerce, custom and headless storefronts, and lead-generation and B2B setups where CRM and offline conversions need to reach the ad platforms. If you're spending real money on paid media and nobody owns measurement quality, the work is the same shape.

We'll tell you. If the Measurement Scan or Conversion Tracking Audit reveals that your tracking is already solid - server-side infrastructure in place, events firing reliably, deduplication working, consent handled correctly - we'll document that and let you know there's nothing material to fix. We'd rather lose a $850 Conversion Tracking Audit than build a commercial relationship on a problem that doesn't exist.

Measurement Assurance begins the day your implementation goes live. The first 90 days are a calibration period: the platforms are re-learning from the corrected signal, and that window is when drift and edge cases surface. We monitor the agreed measurement layer, investigate material anomalies and maintain the implemented configuration as platforms and storefronts change. Monitoring reduces the time between a material issue appearing and it being investigated; it does not guarantee that every platform or site change will be detected before any data is affected. Measurement Assurance covers the existing site, platforms and measurement infrastructure included in the agreed implementation scope. New sites, new markets, newly added ad platforms, major redesigns and material architecture changes are assessed and quoted separately. The engagement renews in three-month terms and can be cancelled with written notice at least 30 days before the next renewal date.

We can't guarantee specific revenue or ROAS outcomes - those depend on your creative, your offer, your audiences, and many variables we don't control. What Avinian commits to is a documented implementation, event-level testing and verification against the agreed measurement plan. Better measurement gives the platforms stronger inputs, but campaign and revenue outcomes still depend on factors outside the measurement layer. Published results from brands running this architecture include a 26% reduction in prospecting CPA (Yves Rocher), a 152% increase in Google Ads orders (myBlend), and a 50% improvement in ROAS (Decathlon Travel). These are third-party published outcomes, not Avinian client results. They reflect the impact of better signal on platform optimisation, which is the same mechanism we implement.
