Automatically exclude out of stock items from Google feed when set to not display out of stock items
If set to not show out of stock products, zero stock items are still in the feed. As the page does not exist, Google adds the product to the disapproved list. Currently this can be overcome by hiding the product, or, where some but not all variants are out of stock, setting attribute "Exclude from Google product feed" to yes. However, especially for seasonal products, it is very easy to forget to reset the attribute when the next delivery arrives, then losing sales.
Automatically excluding zero stock items in the feed when set to not show out of stock items, then adding back to the feed automatically when back in stock, would prevent this.
