Step 4 of 5: Set up conversions with basket data

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

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

Requirements:

• Conversions must measure purchase events
• Product IDs in basket data must match products in Merchant Center
• Basket 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 Set up and test reporting with conversions with basket data to set up conversions in Google Ads and to add basket data to your conversion tags.
   • To accurately report basket data in Google Ads and Google Analytics, add the same product ID to both items.id and items.item_id basket data parameters.
   • To help optimise your performance with automated discounts, assign gross profit as the conversion value in Google Ads. However, automated discounts works with any value that 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 basket data. Otherwise, automated discounts uses the conversion type measuring purchase events that has previously included the highest number of baskets with the required data.
2. If you haven't yet completed a test order to ensure that 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 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 basket 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 that 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.
