A few days ago some customers reported that Google now wants to see the url as well as the priceValidUntil properties for all Offers. Here is how you can deal with this.

Here are the exact warnings that Googles Structured Data Test Tools shows:

• The priceValidUntil field is recommended. Please provide a value if available.
• The url field is recommended. Please provide a value if available.

Update your product snippets

If you have built a product snippet yourself, please make sure to update all offer-properties and the Offer-Child-Schema. As outlined above you need the following properties:

• url
• priceValidUntil

WooCommerce

If you’re using my pre-defined product snippet and/or the Offers field type, please update to version 2.7 of the plugin. It will fix the issue.

Version 2.7 will be available later this day.
