Linkedin is a social platform for business people and academics. To post here you need a different approach to engage the audience as it is very much corporate based and an ideal place to network so it is best to come in with a professional approach.

The age group is 79% over 35's with the age group between 35-49 being the most popular. although I have struggled to interact here so I only post twice a week.

I think I need to still work on my approach here !

I'd still advise posting here as the audience is estimated at 467 million users.

I have also read that Linkedin are working on making Hashtags more common to use so interaction here may improve.
