Server-side tracking for Shopify, built for POAS bidding on Google Ads and Meta.

The app embed loads Product Metrics through Shopify’s app proxy, under /apps/ on your own store domain. An adblocker sees a request to your shop, not to a tracking domain.

Shopify now runs checkout tracking through Web Pixels: scripts in Additional scripts and script tags no longer run on the thank-you and order status pages (Shopify Plus since 28 August 2025, other plans since 26 August 2026). The Product Metrics Web Pixel reports the checkout contact and the completed purchase from inside Shopify’s checkout.

• Adblocker benchmark: which blockers stop the standard Google tags, tested with the real extensions.

Product Metrics reads the visitor’s analytics and marketing choices from Shopify’s Customer Privacy API and passes them to Google Ads as Consent Mode v2 signals. Nothing is granted by default.

The email address is hashed before it is sent, and only when the visitor allowed marketing.

When Shopify marks an order paid, cancelled or refunded, it sends a webhook. Product Metrics then reads the order through the Shopify Admin API: totals, discounts, shipping, tax, refunds and the customer. That read is what reaches Google Ads and Meta, so each purchase counts with the amount Shopify recorded.

A refund or cancellation becomes an adjustment to the same order. The Shopify order ID is sent as the transaction ID, so repeated reports of the order are deduplicated within the same Google Ads conversion action.

Shopify keeps a cost per item on each product variant. Product Metrics reads it on every order line. Shopify Payments fees are read as charged; shipping, packing and other costs come from your cost settings. Lines without a Shopify cost use the cost in Merchant Center.

Product Segmentation works on ROAS straight away. Connect margins to switch it to POAS.

• Break-even ROAS calculator: the return each product needs from its price and costs.

Product Metrics checks the customer’s earlier paid orders in Shopify. The first paid order makes a new customer; every later one is returning.

Each purchase reaches Google Ads and Meta marked new or returning, with its revenue, profit and lifetime value. In Google Ads, that is eight conversion actions Product Metrics creates and manages for you:

• Product Metrics - New Customer
• New Customer Profit
• Returning Customer
• Returning Customer Profit
• Revenue
• Profit
• Revenue LTV
• Profit LTV

Product Metrics shows nCAC, what you pay for a new customer, per product and as an average, so you can increase priority on products that bring in first orders.

• MER and nCAC calculator: work out nCAC from your own totals.

Shopify’s Google & YouTube app connects your store to Google Merchant Center and lists your products for Shopping ads. Keep it: Product Metrics is not a feed tool.

Product Metrics adds what Google Ads bids on and what you act on: every Shopify purchase sent server-side as new or returning with its profit, and your products segmented by clicks and return into Merchant Center labels that your Shopping and Performance Max campaigns use.

• Product Segmentation: products segmented by clicks and return, written to Merchant Center labels.

The usual setup tracks the purchase in the visitor’s browser. Adblockers stop part of it, and Google Ads bids on what is left.

Product Metrics confirms each purchase from the Shopify order and sends it from our server to Google Ads, with Enhanced Conversions and Consent Mode v2. It runs next to your current tag.
