Hello everyone, by linking to the url of my website ( link ) on facebook or linkedin I see a blank image with the title and a little more. What I want is for a predefined image to appear for me. Facebook gives me a little bit the same but I'm very interested in linkedin. I know we have to add some type meta tag:
<meta property="og:image" content="http://www.start2develop.com/wp-content/uploads/2017/11/Start2DevelopLogo.jpg"/>
I tried in the header.php content.php but nothing In what file of my web should I add it? (I use wordpress.org). I've been trying things all afternoon and I'm sure it's silly, a greeting and thanks in advance for the help!
