Hopefully none of this (or very little) overlaps with other posts. I'm really slammed right now with my own Kickstarter, and can't go back over every post.
My Kickstarter is still running (
Arcane Synthesis), but I've learned that they are very hard, heh! You definitely don't want to rush into one. I didn't, and it was still very hard. I spent 6 months researching and preparing to run mine (in addition to months of learning more about how it all works and reading articles) and much of that 6 months was full time. I think a solid year would be good for most people, especially if you have limited time, at least for your first one, and much more so if you are an unknown. And you also need to be prepared to spend a good portion of every day during your campaign to talk with people, share about it, respond to questions, etc.
You also want to get feedback on your Kickstarter from several sources prior to launching.
I also learned that the Kickstarter website is very finicky when it comes to formatting. There are some glitches in their system. For example, there is a maximum number of characters you can use to describe your "story" - your section on info about your project. I went in more than once to fix a typo, rework a sentence, etc. and several times it told me I was over the max character count when I hadn't actually added any characters. In some cases I actually removed sentences and entire paragraphs and it would tell me I went over! And there were 4 times over the period of a month prior to launching, where I would click on a reward to change it, then get a phone call or decide not to make a change, but being the paranoid type, I'd automatically hit the button at the bottom to save, but that can be a major no no!
See, if you don't actually change something, the save button changes to a "Next" button, and that ate an entire day's work 4 times! Because Save only means Save if you don't hit Next! Major glitch that I'm surprised they haven't fixed. I was saving all day long after nearly every change, just to make sure I had no problems, but it would easily erase an entire day's work, regardless of how often I hit the save button, if I ever accidentally hit the Next button (silly that they put 'em both in the exact same spot).
Plan a good amount of time to do everything as it will always take longer than you think! I originally planned for 3 months, then delayed it an additional 3 months to double check all of my math, shipping, etc. and like most I'm sure I still made some mistakes along the way. And you will need many months to build up relationships with your potential backers, spread the word, etc. You will want to study many similar campaigns out there!
Anyway, I hope these tips help you avoid many of the headaches. Our Kickstarter is doing pretty well so far, but I still feel like there's a huge number of fiction fans that don't know we exist yet, despite several hours a day reaching out, even prior to launch.
