If you are posting a link on Twitter you have to remember that this is effectively just a stream of links and musings passing by like a flash in a couple of hours. So if you post a link to your latest hot news story, there's a good chance it will be lost in the flood. If you post a link to the same story on Facebook on average it may linger around for almost twenty percent or half an hour longer before it is lost. 

In both cases the exposure of your post depends on the size of your audience, that's 'followers and friends'. In both cases the more 'followers and friends' you have the quicker your message will be lost, but of course more people would have been exposed to it.

So what's the answer to the great social media debate? Which is best for marketing your care home Facebook or Twitter? I'm sorry I don't know the answer to that one, which is why like many other people I submit links to my stories, articles and web pages which are mostly about care for the elderly in the UK. I submit those articles to both websites.
