I am currently building a website, and decided to use json-ld for providing some semantic information about the "LocalBusiness" (it is a non-profit organization). Of course, the main goal is to improve the search engine ranking, and provide more useful results to a user.
I have written the json-ld structure, and I then put it on the contact page. After some consideration, though, I moved it to the landing page (naked URL, the one that is pointed to inside the json-ld structure itself).
Is this the right page to put it on (according to the web crawlers' behavior), should I put it on more pages, or even on every web page (including the forum)?
Moreover, if this metadata is used by other clients (which I'm unsure of, at this point), such as screen readers, should it be also included on other webpages?
