While it’s just over a year old, can I just say how much I still love the Social Media Posting Guide for Nonprofits by Craig Van Korlaar for Top Nonprofits?
This is a great resource, especially for nonprofits that lack full-time social media or marketing staff. It gets you thinking about social media strategy quickly and easily, without doing a ton of research first.
While there’s a low resolution sample below, you can download the printable PDF version of the guide from Top Nonprofits.
