This attribute contains a direct link to a product page on your website where your item is shown.
The link attribute is required for all items.
The URL your link attribute contains must start with 'http://' or 'https://' and you have to use your verified domain name. If you have variations of a product use different URLs for every product specification. Also use encoded entities if there are any symbols used in your URL.
Don’t remove your items if they are out of stock but enter the value 'out of stock' in the availability attribute of your item.
