When you set up conversions with basket data for automated discounts, that allows Google to measure sales, revenue and profit from your Shopping ads. After you start using automated discounts, if your online shop's setup changes and no longer meets the requirements, Google can't accurately measure purchases from your Shopping ads. Depending on the issue, some purchases could result in negative gross profit. If there are issues with your conversion setup for automated discounts that result in missing or incorrect purchase conversions, you'll be notified in Merchant Centre.
Common causes
Here are a few common reasons why you might encounter issues with your conversion setup:
- Inactive or unverified conversion actions: Your conversion tracking tag may be installed incorrectly or is failing to fire on the confirmation page.
- Incorrect conversion action settings: The conversion action for purchases might be set to 'Secondary' instead of 'Primary'.
- Mismatched product IDs: The product IDs passed in your conversion tag's basket data do not match the IDs in your Google Merchant Center data source.
- Missing basket data: Essential parameters such as price, currency or quantity are not being captured or sent correctly during the conversion event.
Fix issues
To identify and resolve issues, follow the steps below:
- Test your conversion actions with Tag Assistant: Use the Google Tag Assistant to perform a test conversion on your website. This tool will show you in real time if your tags are firing correctly and what data is being passed.
- Test your conversions with basket data: Follow the steps in Test correct implementation of conversions with basket data to ensure that your conversion with basket data metrics are correct.
- Verify basket data and product IDs: In your Google Ads account, select Goals and then select Diagnostics. Note that the diagnostics card will only be visible if you're sharing conversions with basket data in your transactions. The diagnostics tool will flag issues when product IDs in your conversion tag don't match the IDs in your linked Google Merchant Center account. It's important that these IDs are identical.
