I understand you want to import GTIN/MPN values into the Yoast WooCommerce SEO plugin.
It’s currently not possible to import GTIN/MPN values into the Yoast WooCommerce SEO plugin. You are actually not the first to have requested this feature, so a feature request was already created and it is currently under review by our product team.
Alternative option
As a workaround, you could import global identifiers directly to your database. Identifier values are under the wpseo_global_identifier_values field in the _postmeta table. The format of the data in the field is the following:
a:6:{s:5:"gtin8";s:11:"GTIN8-VALUE";s:6:"gtin12";s:12:"GTIN12-VALUE";s:6:"gtin13";s:9:"EAN-VALUE";s:6:"gtin14";s:12:"GTIN14-VALUE";s:4:"isbn";s:10:"ISBN-VALUE";s:3:"mpn";s:9:"MPN-VALUE";}
where the value for “a” at the start is the number of fields, and the “s” before each value is the number of characters.
Another alternative would be to use a plugin like WP All Import. This plugin has a feature in which you can import data via a custom field. You may want to reach out to them for more information.
What’s next?
Our product team will assess the feature request and assign a priority level to the report. Our developers work on the highest priority issues first. We cannot give you an estimate of when or if they’ll start working on the request.
If you have any further information that may affect the prioritization, please feel invited to reply to this forum topic, and we’ll share the information with our product team.
