Why Ad Attribution Breaks
Native platform integrations rely on client-side tracking that breaks at every critical step. Here is how a server-side system keeps the chain intact from ad click to verified purchase.
Native Platform Integrations: The Broken Chain
Attribution & Campaign Intelligence: The Closed Loop
Ad Click (Meta)
User clicks your ad. Meta fires a client-side Pixel event in the browser.
Landing Page Visit
User arrives. No persistent ID is assigned. Session only.
Email Opt-In (Klaviyo)
User joins the list. Klaviyo assigns its own ID, unconnected to the ad click.
Checkout (Shopify)
Checkout runs on checkout.shopify.com in a sandboxed iframe. Cookies from your site cannot be read here.
Meta Reporting
Meta self-reports attributed revenue using its own model. You have no way to verify it against your actual orders.
Ad Click (Meta)
User clicks your ad. The link points to a tracked redirect, not directly to your site.
Tracked Redirect Link
Our server receives the click, logs the ad ID, campaign, and UTM params, then assigns a persistent first-party ID (cm_uid) as a cookie before forwarding to your site.
Landing Page Visit
User arrives on your site. The cm_uid cookie persists across their entire session and future visits.
Email Opt-In (Klaviyo)
When user opts in, cm_uid is written to their Klaviyo profile. The ad click and the email subscriber are now the same person.
Purchase (Shopify)
User buys. Shopify fires a server-side webhook directly to our platform. No browser, no iframe, no cookie needed at this step.
Attribution Match
Our platform matches the order email to the Klaviyo profile, retrieves cm_uid, and connects the purchase back to the original ad click and campaign.
Your Revenue Ledger
Ad → click → email subscriber → purchase. The full chain in your data, verified against your Shopify orders. Not Meta's number. Yours.
Why This Works When Native Integrations Don't
Native platform integrations rely on client-side tracking: code running in the user's browser that can be blocked, sandboxed, or lost between sessions. The identity chain breaks every time the user changes pages, clears cookies, or hits Shopify's checkout sandbox.
This system uses server-side tracking at every critical step: the redirect link fires before the user even reaches your site, the identity cookie is set by our server, and the purchase is captured via a direct webhook from Shopify, bypassing the browser entirely. The identity thread stays intact from first click to final order.
The Three Gaps Native Tools Can't Close
iOS 14+ Privacy Changes
Apple's App Tracking Transparency blocks Meta's Pixel from firing on roughly 60–70% of iPhone users. Our redirect link captures the click server-side before the browser ever loads, so iOS privacy settings don't affect us.
Shopify Checkout Sandbox
Shopify's checkout runs on checkout.shopify.com, a separate domain in a sandboxed iframe. No cookie from your site can be read there. Our platform already has the identity from the redirect step and receives the order via webhook.
Platform Identity Silos
Meta, Klaviyo, and Shopify each assign their own user IDs with no shared key between them. Our cm_uid is written into all three systems at the moment of interaction, creating a single thread that connects a click, a subscriber, and a buyer.
