This plugin generates a strictly formatted XML feed of your product reviews that meets Google Merchant Center requirements. By submitting this feed to Google, you can enable “Product Ratings” (stars) on your Google Shopping PLAs (Product Listing Ads).
Key Features: 
* Universal Support: Works with native WooCommerce reviews, Customer Reviews for WooCommerce (CusRev), YITH Advanced Reviews, and Site Reviews. 
* Strict Schema: Generates the specific nested XML structure Google requires (GTINs, MPNs, Namespaces). 
* Smart Caching: Caches the XML feed to reduce server load. Default refresh is weekly (recommended by Google). 
* Product Identifiers: Maps your GTIN, MPN, and Brand fields to ensure reviews match your products in Google.
Performance & Limits: 
By default, this plugin includes your 2,500 most recent reviews. This safety cap ensures that generating the XML file does not crash your server due to memory exhaustion. 
* Developers: You can increase or remove this limit using the <code>prxml_review_limit</code> filter.
