Join James Williamson for an in-depth discussion in this video Including aggregate reviews, part of HTML: Structured Data.
- Schema.org has a pretty rich vocabulary…for describing products.…And that's especially true for ratings and reviews.…In this exercise, we'll add what's known…as an aggregate review.…So to do that, I'm working in the bars of that HTM file…from the 04_07 directory.…And if you're wondering, "Okay, what's an aggregate review?"…Well if I scroll down, down towards the bottom…of my product details, I can see that its Rating…is 4.5 out of 5 stars with 156 total ratings,…so that's an aggregateRating.…
It's an average out of a certain number or value,…and you're probably gonna have a range of ratings…or how many ratings has been given…for that particular product.…So here we have three properties that we need to structure.…We have the actual rating itself.…We have the range, which was to a five star.…And then, we have the total number of ratings,…which is 156.…So to kind of figure out how to structure this,…I'm going back to schema.org.…And I notice that in my product page,…one of the first options is an aggregateRating.…
