We have product pages with multiple reviews. Some have 200. 300 reviews. Obviously we do not put them all in the page html on page load - we show 5 as default. A person can hit "see more views" - 5 more will be ajax loaded, etc.
How many should we include in Schema markup (JSON-LD)?
I see some not include reviews at all - just aggregate rating. I see some people including 5-10 reviews, I saw one page including 50 reviews. Theoretically we can include all of them (not to slow down page we can wait for DOM ready and than make data push). I just wonder if it makes sense.
