If there is one social media platform that is exclusively business-to-business in it’s approach and ethos it has to be LinkedIn. This platform has consistently made clear that it is the home for professionals on social media. It has to be said that LinkedIn’s thorough approach to this ethos has kept it going for many years. Even though it kind of started out as a place where professionals can communicate with each other and not much more, it has now become somewhere that fosters business relationships. And on top of all of that, it has also become a pretty powerful advertising platform.
