I read the article The Complete Guide to Creating On-Site Reviews + Testimonials Pages. I would like to create my own solution on our website to collect reviews on our website that Google can find. I'm not 100% sure if I understand this correctly.
So I would create a form with appropriate inputs and take that user input and create a JSON-LD object in a <script> tag and place that in the head of our /reviews/ page. So each review listed on our /reviews/ page would be in an array of JSON-LD objects, and that's how Google can find it?
Is it as simple as that? Placing the JSON-LD in the <head> with the correct data?
This site was used as an example on the article I linked. They use a third-party service that is basically doing what I am going to set out to do. I don't see the data in the head when viewing source, but I guess it's a good practice to hide the JSON-LD somewhere? I see a JSON-LD script, but it's empty.
Can someone help me understand this better?
The idea is to provide machine-readable structured data about the reviews, using the vocabulary Schema.org. Three syntaxes are supported: JSON-LD, Microdata, RDFa.
See a comparison. With Microdata and RDFa, you would add HTML attributes to the existing markup for the reviews. With JSON-LD, you would add the structured data in a separate script element and leave the review markup untouched.
This script element can be in the head or in the body. By default, it’s visually hidden no matter where it’s placed.
If you provide such structured data, consumers (like Google Search) may make use of it. For example, Google Search offers the Review rich result feature. Their documentation describes which Schema.org types/properties are needed to qualify for it.
