Google uses the Open Graph tags that JFBConnect will try to set automatically on each page. If you're having issues, I'd recommend trying to run the URL through the following tools:
Social Debug
- This tries to debug all social tags and simulates the types of posts that would be made
[url=https://developers.facebook.com/tools/debug[/url] - Facebook's Open Graph Debug Tool which shows all the tags it sees.
Between those 2, hopefully any issues will be raised to diagnose. If not, please let us know the exact URL of a page with problems and we'll gladly help look into it further.
Thanks,
Alex
