Facebook links

I thought that the system we are using to copy new posts from our web site to Facebook was working. I could see them but it appears that some others cannot. But some of the Facebook posts show “Seen by 10” (or 6 or 12 or whatever) so it looks as though some people can see them. It would be great if some of you could comment on this post on Facebook so that we can check what is hapenning. Thanks. Just added a picture which I have not been doing, just in case that was the problem.
