adding more info to url when sharing post to facebook

Hi there,

To instruct Facebook and many other services what to show in a share or preview on the Newsfeed, you need to specify Open Graph meta tags. I would suggest adding the Open Graph tags (og:image, og:description, og:title, and og:url) to each of your pages.

Here’s some more information on Open Graph tags:

If you’ve already added Open Graph tags, I’d suggest looking at the Facebook Debugger to see if Facebook is reporting any errors:
