Only in its second year, #GivingTuesday has already swept the nonprofit world. A charitable answer to Black Friday, Small Business Saturday and Cyber Monday, the organizers aren’t shy about their hopes to make the day as big as Black Friday. Even the Canadians are in on the fun!

This year, charity partners are up to 7,500 from 2,500 last year, thanks to the success of last year’s campaign. Online giving was up more than 50% on the Tuesday after Thanksgiving in 2012 compared with the same Tuesday in 2011.

But, since #GivingTuesday originated online (as if the # in the title didn’t give it away), participating nonprofits have to have a strong social media strategy to truly take advantage of the day. With a built-in and already popular hashtag, social media teams can piggy back on the ongoing conversation to add their voice to the conversation, engage with followers and others who are participating in #GivingTuesday and attract new donors through outreach across their social channels.

Data also plays an important role in a day devoted to fundraising and social media. Beth Kanter, whose blog on using data and networks is a must-read for nonprofit leaders, has a helpful post up today on using data on #GivingTuesday. The post stresses, in addition to the importance of a social media strategy, auditing the giving experience, getting the right data and segmenting new donors.
