The only platform where you can target what someone actually does, rather than what they like.
No other platform lets you advertise by job title, sector and company size at the same time. Cost per click is higher as a result, but you don't pay for everyone it has nothing to do with.
Posts from a personal profile usually get more reach than the same text on a company page. If you take that seriously, you let the people in the organisation publish and use the company page as a reference.
With cost per click of five to ten euros, the value of a customer needs to be high enough. For a service worth a few hundred euros it rarely works; for projects worth tens of thousands of euros it is often the cheapest channel there is.
