Everyone says it’s hard to measure social good success. Well, non-profit consultancy Convio begs to differ. The firm recently put out an infographic showing that the Internet is the fastest-growing channel for non-profits. The graphic compares money raised, awareness gained and a variety of other factors across a three-year period. Since 2008, non-profits have cracked the $1 billion mark for online fundraising. In 2010, the average online gift jumped up to $91.94. There’s clearly a long way to go for online fundraising and social good when compared to the huge sums still collected through traditional fundraising and offline giving, but the upward trend certainly bodes well for digital philanthropy.
