The Signal 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) 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 full Signal 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.

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.

We build on Addingwell's server-side infrastructure, combined with Google Tag Manager server-side containers, Meta Conversions API (CAPI), Google Enhanced Conversions, and Shopify's Customer Events API. This stack routes conversion data from your Shopify store directly to your ad platforms via first-party server connections, bypassing the browser restrictions and consent limitations that cause client-side tracking to fail. Addingwell is a specialist server-side platform used by brands including Yves Rocher, myBlend, and Decathlon Travel. For stores with custom event requirements or specific integration needs, we configure the stack around your setup.

The free Signal Scan requires no account access - it's based entirely on what's publicly visible from your storefront. The full Signal 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 Signal 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.

Our core focus is Shopify - it's the platform where we have the deepest experience and where the checkout sandbox and pixel limitations create the most consistent, significant tracking gaps. That said, we assess other e-commerce platforms (WooCommerce, Magento, custom stacks) on a case-by-case basis, particularly where a brand is running serious paid media budgets and the infrastructure gap is clear. If you're not on Shopify, get in touch and we'll tell you honestly whether we can help.

We'll tell you. If the Signal Scan or Signal 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 audit than build a commercial relationship on a problem that doesn't exist.

The retainer (Avinian Measurement Assurance) is an ongoing engagement that begins after implementation. We monitor your tracking infrastructure continuously - when Shopify updates change event behaviour, when Meta pushes new CAPI requirements, when browsers tighten restrictions - and we maintain the setup so it keeps working without requiring your team's attention. You receive a monthly measurement health report and direct access to us when something breaks or needs investigating. Retainer pricing is scoped to your store and infrastructure.

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 we can guarantee is that your ad platforms will receive a more complete and accurate picture of your real conversions. Published results from brands using this infrastructure 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 reflect the impact of better signal on platform optimization - the same mechanism we implement.
