When you share a post on Facebook, or when Jetpack Publicize publishes a post to your Facebook page, Facebook crawls the page and looks for Open Graph meta tags in the head to build a complete post preview (with an image, title, description, …).
Jetpack automatically generates these meta tags for you, unless you already use another plugin to generate them.
You can see what Facebook sees by entering one of your posts’ URLs in Facebook Debugger:

@prosperewebitor You’re using the WordPress SEO plugin to manage your Open graph meta tags, but you haven’t configured them yet. Could you go to SEO > Social in your dashboard, and configure your Meta tags there?
if that doesn’t help, you’ll need to contact the WordPress SEO plugin authors for help.
@kkrousseau The Meta tags seem to be correctly added to your posts. Next time you publish a new post, and if you still experience issues, could you copy the link to the post as it appears on Facebook, and paste it here?
Thanks!
