You might have come across LinkedIn profiles that have attached different rich media (pictures, YouTube videos, links, etc.) to either their summary or experiences.
But why are people doing it?
First of all, it might be for the simple reason that it looks professional and it makes a good division between your employments. However, from a business perspective, it is an easy way to promote your company and increase the possibility for traffic to your website.
In order to insert rich media, go to the top of your experiences and click on the square with a “+” sign next to “add position”, and from there it is very intuitive.
And if LinkedIn should give you a hard time and give you an error message, do not give up, sometimes all it needs is a few tries.
