We struggled for a long time trying to create an automated feed. For more than a year, we were manually creating our product feed outside of Shopify. With such a manual process and limited resources, we were only able to manage a single product feed on Google Merchant.
With SmartFeed's app, we were finally able to create an automated feed, which has significantly increased our revenue on Product Listing Ads. Beyond the App, Smart Feed provides us with excellent customer service. They helped us throughout the set up process with the various Comparison Shopping Engines that we are now successfully running product ads on.
