I would like to ask if is there any difference when I have description and og:description separately and together. Is there just only difference that when it's separately I can add different text and when it's together, so same text is used for both ?
<meta name="description" content="Lorem ipsum" />
<meta property="og:description" content="Lorem ipsum" />
Together
<meta property="og:description" name="description" content="Lorem ipsum">
<meta>
tag does not use and does not need a closing slash and never has in HTML. – Rob Nov 19 at 10:51
