Install the OpenGraph microdata that allows Facebook to automatically build a Product Catalog when someone visits your WooCommerce products.
What does the Smart OpenGraph plugin do?
If you have the Facebook pixel installed on your website and the required OpenGraph microdata on your product pages, you can use the activity your pixel captures to build Facebook Product Catalogs.
When the pixel fires on your website for a product, the product is added to your catalog.
The plugin inserts the mandatory microdata on WooCommerce product pages.
