Review-aggregate?

Hey @lem45!

It sure is!

If you want to output the Aggregate Rating structured data, you need to use the testimonials count shortcode to do so.

We have a page with different examples of this shortcode, here:
https://goldplugins.com/documentation/easy-testimonials-documentation/easy-testimonials-installation-and-usage-instructions/output-a-count-or-aggregate-rating-of-testimonials/

I believe the following shortcode would do the trick:
[testimonials_count show_aggregate_rating='1']

All the best,
Richard
