WooCommerce: Fix Google Search Console “No global identifier provided” Error
If you registered your WooCommerce website on Google Search Console for monitoring your SEO efforts and search appearance errors, you probably got this “No global identifier provided (e.g. gtin, brand)” email notification at some stage. I got it too.
Search Console optionally requests you set a unique product GTIN structured data for all your products – I believe in case you wish to sell on Google Shopping – and therefore sends you this error notification whenever a product is missing this.
You could use a WooCommerce GTIN plugin from the WP repo, yes. Or you could be smart, and programmatically set the GTIN to the same value of the product SKU, as long as all your products have a unique SKU value. Today, we will cover the latter. Enjoy!
PHP Snippet: Programmatically Set Product GTIN Based on SKU
Please let me know in the comments if everything went as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting.
