What are JSON LD Rich Snippets

Simply put, structured data helps search engines put the multitude of information on a website into context. For this purpose, the content is linked to further information. Search engines can use structured data to better determine what a website is about. This does not increase the number of hits, but the quality of the hits improves because the offer can be dealt with more precisely. JSON-LD is Google's preferred format for structured data. It is highly likely that Google sites with JSON-LD will rate information better than sites with other markup methods.
