Why my meta tags not working on FB or Whatapps

Hi everyone,

I have create a Sitefinity page added some meta tags the following

<meta property="og:title" content="mantap" />
<meta property="og:site_name" content="Eddy Sites"/>
<meta property="og:description" content="Description-Nasi gerobag" />
<meta property="og:image" content="https://xyzsite/myimage.JPG" />

but when i run the page and pasted the url into whatapps or facebook, the meta informations do not show up,
what is missing

Thanks in advanced

Hi xman,

It looks like something is wrong with your opengraph markup. Please try to post your url to this debugger: developers.facebook.com/.../ It should show errors and warnings for you
