Why doesn’t the plugin send google_product_category by default?

Because it’s optional and not required for a valid Google Merchant feed. Leaving it empty is safer for a broad audience: Google can infer a category automatically, and advanced users can still provide an explicit category via the tdl_gmc_google_category filter.

How do I add a Google Product Category?

By default, LITE does not send <g:google_product_category>. If you really need it, add this filter in a small mu-plugin or your theme:
add_filter('tdl_gmc_google_category', function($cat, $product){
// Example: Tea & Infusions
return 'Food, Beverages & Tobacco > Beverages > Tea & Infusions';
}, 10, 2);

Where is my feed URL?

Use /3dl-gmc-feed.xml (or legacy ?zd_gmc=1).

How do I include GTIN/EAN?

Add your meta keys in 3DL GMC Settings or use standard keys from common plugins/themes (already detected).

Is PRO required?

No. LITE is fully usable. PRO only unlocks advanced features.

1.1.7

  • Remove automatic google_product_category mapping; by default LITE does not send GPC.
  • Docs: add FAQ showing how to provide GPC via the tdl_gmc_google_category filter.

1.1.5

  • Rename slug and text domain to match WP.org rules.
  • Escape all dynamic XML values (PHPCS).
  • Avoid WooCommerce internal meta notices for _global_unique_id.
  • Use THREEDL_GMC_CAP (default manage_woocommerce) for admin access.
