Product Schema Properties

Here's a table of the properties you can define in the Product Content Type.

Name	Description
Title	The name of the product.
Description	Product description.
Image	The URL of a product photo. Pictures clearly showing the product (for example, against a white background) are preferred.
Rating Value	The rating for the product.
Review Count	The count of total number of reviews.
SKU	The stock keeping unit of the product.
Brand Name	The brand of the product.
Price	The price of the product.
Currency	The currency used to describe the product price, in three-letter ISO 4217 format.
Condition	The condition of the Product. Eg: New, Damaged.
Availability	The availability of the product. Eg: InStock or OutOfStock.
Price Valid Until	The date after which the price will no longer be available. Your product snippet may not display if this property indicates a past date.
Google Product Category	Choose the category that best matches your product from Google’s product taxonomy to override Google’s automatic categorization. You can provide either the ID or the full path of a Google Product Category.

General rule: Always markup content that is displayed on the page to visitors. Doing otherwise you may end up with a Spammy Structured Markup Penalty.

Troubleshoot Product Errors and Warnings on Google Structured Data Testing Tool and Google Search Console

Warnings

Warnings are not errors. In most cases they tell you that some recommended fields are missing and in most cases your rich snippet will show up in search result even if there are warnings.

missing field aggregateRating

This warning occurs when the page you're marking up doesn't have any ratings yet. For example, if you're trying to markup Joomla! Articles, you will need to enable a compatible rating plugin to start accepting user ratings. If you're using Virtuemart or HikaShop, the Rating option must be enabled in the respective component setings to enable ratings in the front-end. Once the page gets its first review, the warning will disappear.

The review field is recommended / missing field review

This warning occurs because the review property is not included in the generated structured data at all as it's not supported by the Google Structured Data extension yet. Once this property is added, the warning will be automatically fixed by an release update.
