Full review or excerpt for Schema.org's "reviewBody"

Question

I'm using rich snippets to my blog, my blog is about movies, there is a section call "reviewBody": There you can write (or copy paste) your review.

Should I paste all my review or just an excerpt from my review?

Because I think that Google just take a summary, but I don't know if I have to paste everything or just a summary.

Answer 1

You can visit this resource from Google specifically tailored for your question: https://developers.google.com/search/docs/data-types/review-snippet

Google broke done each JSON-LD property tag with a full description; you can also test your code before publishing using the structured data markup test tool (also by Google): https://search.google.com/structured-data/testing-tool/u/0/

Answer 2

According to Google’s Review snippet documentation, Google doesn’t make use of the reviewBody property, as it’s not listed under "Required properties" nor "Recommended properties".

If you provide this property, it has to contain the full review, per its definition:

The actual body of the review.
