Google Search Console alerts users when certain pages submitted in the sitemap are set to no-index and generates a coverage error, this can include WooCommerce pages like…
These pages shouldn’t be cached or indexed and are correctly set to noindex, to remove the error you can add them to your robots.txt file
User-agent: * Disallow: /cart/ Disallow: /checkout/ Disallow: /my-account/ Disallow: /*add-to-cart=*
You may also get coverage errors on WordPress folders with the error called ‘Server error (5xx)‘, to get around these ensure that you WordPress core files are also excluded in the robots.txt file
User-agent: * Disallow: /wp-admin/ Allow: /wp-admin/admin-ajax.php Disallow: /wp-includes/ Disallow: /cart/ Disallow: /checkout/ Disallow: /my-account/ Disallow: /*add-to-cart=*
So that will fix the WordPress core files coverage error.
