In addition to presents and plane tickets, another type of spending tends to soar around the holidays: charitable donations. Many charities collect the bulk of their individual contributions during the holiday season, especially since Dec. 31 is the deadline for tax-deductible giving.

What’s more, 51 percent of Americans said they are likely to give a charitable contribution as a holiday gift this year, according to a survey by Harris Interactive for the nonprofit World Vision.

One company offers a way to help fundraisers spur donations by using the social Web. Fundly allows its users to set up online giving pages and share them with friends on Facebook — thereby maximizing the number of people who see each contribution. So far, its users have raised more than $233 million using the platform.

We sat down with Fundly CEO Dave Boyce to find out how to build a better social giving campaign.
