Social media allows nonprofits to increase awareness, engage with others, and build relationships at a low cost. Popular social media platforms include Facebook, Twitter, YouTube, and LinkedIn, which have hundreds of millions of active users each day. Nonprofits can use social media to share news, events, photos, and videos; ask questions of and interact with followers; recruit volunteers; and strengthen their brand in order to gain support for their cause. Proper planning is required to allocate staff time for social media management and to establish response and success measurement policies.
