Hi! For the Organization I recommend to add the JSON-LD format only on one page (About or Home). Here is an article about this Organization Schema Markup: Step-by-Step Guide for Companies
Here is an example from Organization - Schema.org Type
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "Organization",
"address": {
"@type": "PostalAddress",
"addressLocality": "Paris, France",
"postalCode": "F-75002",
"streetAddress": "38 avenue de l'Opera"
},
"email": "secretariat(at)google.org",
"faxNumber": "( 33 1) 42 68 53 01",
"member": [
{
"@type": "Organization"
},
{
"@type": "Organization"
}
],
"alumni": [
{
"@type": "Person",
"name": "Jack Dan"
},
{
"@type": "Person",
"name": "John Smith"
}
],
"name": "Google.org (GOOG)",
"telephone": "( 33 1) 42 68 53 00"
}
</script>
