Step 4 of 5: Set up conversions with cart data

Cart data from purchases allows Google to measure sales, revenue, and profit from your Shopping ads.

Automated discounts uses this information when selecting products, optimizing discounted prices in your Shopping ads, and reporting your profit performance in Merchant Center. Google Ads also uses your conversion and cart data when reporting your product and campaign performance.

Requirements:

• Conversions must measure Purchase events
• Product IDs in cart data must match products in Merchant Center
• Cart data must include a price value, such as 15.00
• Total price of all items in a cart should be higher than the items’ total cost of goods sold

1. Follow the steps in to set up conversions in Google Ads and to add cart data to your conversion tags.
   • To accurately report cart data in Google Ads and Google Analytics, add the same product ID to both items.id and items. item_id .
   • To help optimize your performance with automated discounts, assign gross profit as the in Google Ads. However, automated discounts works with any value you choose.
     
     Note that Automated discounts doesn’t support Floodlight conversions or Search Ads 360.
     
     Automated discounts calculates your gross profit using Primary conversions when they include cart data. Otherwise, automated discounts uses the conversion type measuring Purchase events that has previously included the highest number of carts with the required data.
2. If you haven’t yet completed a test order to ensure your conversion tag parameters are set up correctly, do the following steps.
   1. In your Chrome web browser, open Chrome DevTools by selecting the More icon 👁 3 dot menu icon
      in the top-right corner and selecting More tools > Developer tools.
   2. In the DevTools panel, select Network.
   3. Submit a test order for a product that includes a minimum price and cost of goods sold.
   4. Search for “/conversion” which includes the request that contains your conversion. The query string parameters should include the cart parameters, as shown in the following example:
      
      mid = aw_merchant_id
      fcntr = aw_feed_country
      flng = aw_feed_language
      dscnt = discount
      bttype = event type
      item = items (the array) mapping all items with (items.id * items.price * items.quantity)
      
      Make sure taxes are applied consistently. If you include sales tax or VAT in COGS when you add products to automated discounts, the tax must also be included in the items.price parameter; if not, exclude tax from both.
