I tried adding the abstract code in the meta tags (in article display.tpl), but that is showing in the main article page instead. This is the code what I have used. I want to show the description in the snippet, so what code should I use?
<meta property="og:description" content="{$article->getLocalizedAbstract()}|strip_unsafe_html}" />
Currently I am using authors name.
Dr. @Vitaliy, I think you are the only one using it. Is my code correct?
