Revws module - possibly missing product structured data

[30knees]

Google Search Console tool shows me this:

Either "offers", "review", or "aggregateRating" should be specified

Items with this issue are invalid. Invalid items are not eligible for Google Search's rich results

I use the Revws module: https://store.getdatakick.com/en/modules/revws

@datakick Would you have an idea?

This is google being stupid, that's all.

This warning is displayed when product doesn't have any reviews yet.

We obviously can't write any metadata about review (author, content, rating) because none is written yet.

We also can't write any metadata about aggregateRating - because what is the average of nothing? Allowed value for this field is in range of 1 to 5.

• If we used 0, then google would complain that this not a valid value
• we could put some value from the allowed range, but which?
  • 1 -- that's not good, because then the page would be displayed with 1 star in search
  • 5 -- that's better, but we would be lying -- nobody gave us 5 stars yet. And google could, and would penalize your site for that.

The only solution here, in my opinion, is omit the information completely.

Ok, thanks. Yes, Google should have permit some "no ratings yet" value. Will try to get customers to review. :)
