What means "Internal JSON-LD"?

JSON-LD (JavaScript Object Notation for Linked Data) is a method of encoding linked data using JSON. In general, JSON-LD is used to prepare information on the internet in a uniform, structured and machine-readable way. In practice, JSON-LD is used to provide structured data about products, companies, services, etc.
Internal" JSON-LD means that the “Linked Data” is contained directly in the HTML page and is not integrated via an external service such as gtag (Google Tag).


Example of JSON-LD in the <head> Section of an HTML Page:

<!doctype html>
<html lang="en">
<script type="application/ld+json">
    "@context": "",
    "@type": "Product",
    "name": "Sample Product",
