Google Performance Max campaigns
Google Performance Max campaigns help you to promote your products and increase traffic through paid advertising. Google is replacing Google Smart Shopping campaigns and upgrading to Performance Max campaigns.
Starting in mid-August 2022, all new Shopify Google channel installs have Performance Max campaigns. Additionally, creation and management of your campaigns will move from the Google channel to Google Merchant Center. You will be able to access Google Merchant Center from within your Google channel.
Starting in early September, all existing Smart Shopping campaigns in the Shopify Google channel are automatically replaced by Performance Max campaigns.
Google Performance Max campaigns have equivalent features to Smart Shopping campaigns, with added functionality and inventory. Performance Max campaigns help you to maximize your ad performance across all Google channels, including YouTube, Google Search, Gmail, and Google Maps. You can learn more about Performance Max and the upgrade from Smart Shopping to Performance Max from Google Ads Help.
