Linkedin

on linkedin is it better to have a company page or personal profile? what about a linkedin group?

For what ?

Personal profile

Personal profile is best. I would make a company page as it looks better to have the logos of your company in your profile.

As for groups, they are dead on LinkedIn. There are a few here and there that are well moderated, but typically they are small and exist in a niche around a location.

Stick to building your personal brand on LinkedIn with video content.
