Some advice!!!

How are the different languages set on your site? Open Graph tags and sharing in general work on a URL basis. If all the languages use the exact same URL but are translated based on some cookie, then you'll have a difficult time.

For each page using a specific language, the answer is the same. If you have two pages, like:
site.com/en/page-1
site.com/de/page-1
Then JFBConnect should automatically set the description and title for the page based on the content. You could also use the {SCOpenGraph description=...} tag or title tag to set the specific title and description for each of those pages in the native language.

I hope that helps give some ideas, but if not, let us know more about how your pages will be unique for each language and we'll try to help however we can.

That setup should work just fine. Can you tell me what issues you're running into with that configuration? JFBConnect should be generating a different title, description and image based on the contents of the page itself. If not, let us know.

I just re-read "Every page have description and own keyword i like take that description ".

If you don't want JFBConnect's automated Open Graph tags to be used, you'll need to manually set the tags on each page, like:
