The new feeds experience and Opportunities launched to Merchant Center tools, now let you add or override your product data with supplemental feeds.
Unlike earlier, where you could only submit to one primary feed, the new supplemental feeds help submitting and modifying product data from multiple sources. This can be use to add or override attributes and values in the primary feed.
Retailers can also now launch their products globally with a single multi-country feed. Adding new countries with the same language to primary feed, "will automatically show your prices in the correct currency of the user," writes Shopping team.
Additionally, you can also pull language-dependent values from a supplemental feed, like title and description by apply "Feed Rules" to reach new countries with different languages.
Google also now enable modifying of product data from the Content API with Feed Rules — meaning, the product updates can be done without making changes to feed directly. For example, you can "apply custom labels based on other values, or complete shipping values based on product weight values, or append strong brand values to the beginning of product title values."
The new Opportunities tab in Google Shopping will now surface a information card that provide an idea of the potential results and effort needed to improve product data or campaigns. "From minor adjustments to important feed fixes, each card pulls in dynamic information to help you prioritize your resources and drive more clicks to your account. Initial cards will show on a limited basis and focus on improving your product data quality," writes Google.
Google says as they're constantly working, more opportunity types will be coming in the future.
Lastly, retailers can also now add multiple team members to Merchant Center account, as either admin or standard users. Once done, users can opt into important news and notifications, including feed alerts, tips and best practices, and beta opportunities — simply by managing their own email preferences.
Additionally, users specified as email-only, will only receive communications, and can't log into your account, says google.
