Social | Test share for Facebook, Linkedin, Twitter

For a customer’s request, i need to add a “share this” for single news on his website.
Hi wants to share on facebook, Twitter and Linkedin.

First of all i need to add all OG meta in the header of the pages that i want to share

<meta property="og:title" content="HTN Telemedicina - VIRTUAL HOSPITAL, maturi già a vent’anni.">
<meta property="og:description" content=" Telemedicina in Italia: sono passati oramai ventun anni dalla sua fondazione e HTN Virtual Hospital ne ha fatta di strada: dalla prima sede di Boario Terme, dove la connessione a internet era garantita dalle linee telefoniche analogiche, alla moderna sede di Brescia in Via della Volta, connessa in fibra ottica ultraveloce.">
<meta property="og:type" content="website" />
<meta property="og:url" content="" />
<meta property="og:site_name" content="Health Telematic Network"/>
<meta property="og:image" content=""/>
<meta property="og:locale" content="it_IT"/>

Next i need to test how news appear once are shared, so every social have his hown tool for testing this:
