This is an important question and unfortunately the answer is specific to each campaign and also depends on your category.
For instance, I personally notice more campaigns coming from the technology/gaming/tabletop categories that attract more strangers from the actual Kickstarter platform than campaigns in the publishing or art category.
I've already taught you how to
reverse engineer Kickstarter campaigns. I'd recommend using the tactics I described earlier to determine the level of traffic that came from the founder's social network along with the types of backers that supported the campaign.
That being said, these are the general sources I usually see backers discovering campaigns:
1. Kickstarter Itself
2. Direct outreach via the project team to their social network (emails, direct facebook messages, calls)
3. Social Media (Twitter, Facebook, LinkedIn, Google+, Pinterest, Tumblr).
4. Online groups (Forums, Social media groups)
5. In-person events (Meetup.com, networking groups, giveaways, trade shows, conventions)
6. Social Bookmarking websites (usually articles shared about the campaign that have been written) - Reddit, StumbleUpon, Delicious, Digg, SlashDot, Scoop.it)
7. Blogs and publications (media coverage)
8. Youtube/Radio.
9. Cross promotion with other creators.
10. Existing email lists (from your blog or business).
