Social media can help non-profits in three key ways: 1) Broadcasting messages to extend reach, 2) Engaging with supporters through conversations to build relationships, and 3) Enabling supporters to support each other through sharing stories and experiences. Case studies on charities like St. John Ambulance, Helen & Douglas House, and Princess Royal Trust for Carers demonstrate using tactics like videos, photos, and online support communities to leverage social media for fundraising and awareness. Consultation with supporters is important to ensure online services meet their needs.
