I’ve just finished a new site for a client, and the Twitter ‘share’ buttons in blog posts are not creating tweets with previews for the linked pages. The tweets themselves post fine, and the links work ok. They just never show the images or page preview for the linked page.
Example blog post from the site - http://leebartlettbestseller.com/blog/196-the-most-feared-sales-objection-really
Any help on this would be greatly appreciated
