There is an opinion that B2B marketing in social networks works inefficiently. The audience of such platforms is used to entertaining content, expert opinions can be found on the pages of individual users, and groups in general are only needed for selling goods in the B2C sphere. “Big group companies don’t look.” But communities on Linkedin are a separate “universe”. The whole concept of a business social network is tied to the exchange of useful information and experience, building a list of useful contacts and joint professional growth. And it is done with an emphasis on long-term profit. On Linkedin, it is easy to find customers who are interested in complex products. Also, it is not difficult to find partners or third-party specialists for the development of your project. Linkedin users are open to professional dialogues and are looking for information that will be useful to them.
And they do it in particular with the help of groups. In Linkedin, your users in the group are an audience close to you, with whom you need to constantly interact, and only then work further on the sales surge. You can use even a small audience as a focus group. Conduct surveys, learn about needs, share information and get feedback. The Linkedin group is an additional sales tool. If you are engaged in mass sending of invites and you have gathered many friends in your personal profile, then it makes sense to invite them to your community. This is a simple solution that takes 1 hour a week, but helps to quickly build the image of an expert on the subject in the eyes of the target audience, selling your product more often and better.
