Costs
The vast majority of non-profits spend less on their websites than they do on pretty much anything else from what I can tell. Much of my professional career was spent creating, running and expanding the Toronto Star's website. We spent a LOT of money doing that. And we brought in a WHOLE LOT of money. I would love to crunch some subsets of numbers with this survey to explore the question of whether spending money on a non-profit's website leads to positive returns - I just don't have a large enough pool of respondents to do that. Regardless, we know that 1 out 10 non-profit websites contribute significantly to their revenues, so the answers are out there.
