Users commend the WordPress plugin for its effectiveness in seamlessly integrating shop content with Google Merchant Center and occasionally Facebook. They appreciate the swift and supportive customer service, often resolving issues quickly. The plugin is praised for being fast, easy to use, and cost-effective, creating necessary tags and eliminating Google Merchant warnings for large product inventories efficiently. However, a notable drawback is the need to purchase a pro version for accessing certain features, such as selecting a single product category in the feed. Additionally, there's a specific issue with URLs for Cyrillic attributes, requiring manual coding to resolve.
