I'm new to JSON-LD. I find the syntax fairly straightforward but my query lies more with deciding which pages it is best to add the JSON-LD to. I've spent a bit of time looking for an answer online but so far nothing has been clear.
My example:
The site is for a business that has roughly 20 branch locations across the country. Each office has a dedicated contact details page, and there is also a "contact us" page for the site as a whole.
Should I
A: Add 'Organisation' JSON-LD snippet for the organisation as a whole to the homepage of the site, and then add individual 'LocalBusiness' JSON-LD snippets to each office details page?
B: Consolidate all this into one snippet of JSON-LD that has 'Organisation' with nested 'LocalBusiness'es and place it on ALL office pages, with a separate 'Organisation' snippet for the homepage?
C: Consolidate all this into one snippet of JSON-LD that has 'Organisation' with nested 'LocalBusiness'es and place it on ALL pages sitewide?
D: None of the above... Instead you should ____________________.
I realise there may not be one correct answer for this, but any help at all in achieving what would be considered best practice, would be greatly appreciated!
Cheers
