Did you know that you can leave comments on posts on behalf of LinkedIn Company Pages tied to your linkedIn profile?
(License Level Required: Professional or Power User)
Just click the Profile Picture button next to a post you want to reply to. Then, click the logo for the Page of which you are an Admin, to engage with the post on behalf of that Page.
By the way, you don't need to add your company as a new User on your Aware account in order to engage as the brand.
What's the ideal strategy here?
Usually, you'll want to engage on behalf of your brand rather than yourself when the situation calls for a company-level response, a more pitch-like response, or a bit of mystique as to "who is behind the brand?". Whereas it's more common to engage as yourself vs as your brand, since most of social selling happens on a personal level.
