1) Go here : https://search.google.com/test/mobile-friendly
2) Paste a page URL having the JS code inside
3) Check the HTML
3.a) => end of the <head> section => there is a JSON-LD if the page is a target page
3.b) => in the <body> => search for links with class=”inlinks”
Example : https://inlinks.net/fr/audit-semantique
