FAQ
-
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_categoryfilter. -
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.
