This here is my favorite PRO TIPs. And it's super easy: Once a funder makes their gift, thank them on Facebook.
When you thank them, make sure you include the link back to your campaign page. Friends of friends will keep seeing you saying thanks and the same link all over their news feed, and will eventually have to check it out (say after 3-4 touches).
By doing this, you're essentially "spamming" your network on
Facebook, but in the nicest way possible because you're
thanking people for being awesome and
generous.
This little trick generated 67% of the traffic for my Birthday Blitz (1,129 total unique visits). That's 67% of my traffic coming from Facebook vs. only 5% from Twitter & LinkedIn, combined!
