A social enterprise is an organization that applies commercial strategies to maximize improvements in human and environmental well-being, rather than maximising profits for external shareholders. For a social enterprise, social media can be the essential tool that builds the ties between the organization and the community.

Why should we use social media as an essential tool? Well, it can help to achieve some of your potential goals.

Making partnerships — Social media monitoring may help you find and reach out to new partners.

Identifying financial contributors — Easily available public information could help you seek donations.

Recruiting volunteers with the right skills — These platforms are an excellent source of active volunteers who are willingly part of the conversation.

Crowdsourcing new ideas or solutions — A call to action can be spread more quickly through social media than via traditional avenues.

Promoting your mission — Because you can post frequent details and updates, social media is a great low-cost marketing tool.
