I've been wanting to post here for some time (My campaign funded in January), but now I've got the full time job of actually making what I promised in the Kickstarter, so time is extremely tight.
One thing I learned (and as I said above, I did my homework, but for every new tip I learned, I discovered that there were at least 10 more to learn), is that while you want the Rewards to be good, you can always beef them up later if the campaign looks like it needs it. As it is, I gave away more than I needed to and it's sucking my time away.
See, I believe in being generous, so my
Arcane Synthesis Kickstarter had very generous Rewards for the amounts I was asking for. I gave away a lot of stuff, even at low tiers. I wanted to. I worked out all the math. I was willing to do it - to give away goodies without losing my shirt, and spent dozens of hours pouring over the tiers to make them exactly the way I wanted. Overall, I think I had a pretty awesome campaign set up. I think my video could have been a tad better - little things here and there could have been better (hindsight), but yeah, overall, I think I did it "right".
I studied like mad the dynamics of campaign design and reward distribution, but I wanted mine generous. And I wanted lots of small dollar backers too (that's much more important than you might think!), so I set up 3 uber low tiers ($1, $2 and $5).
The $5 reward was truly unique - nobody was doing the type of reward I was offering. It was an unusual, cool idea! But ultimately, I just didn't have a big enough fan base to support having that reward in there and it cost me the same amount even if I only got 1 backer (be very wary of that sort of thing - I was convinced that tier alone would net me many backers and some of those would then be enticed to move up to higher tiers). The cost? Mostly time. That's a big cost though and my most precious commodity - and hardest to find treasure.
I ended up with only 1 at that tier (and 76 backers total). So, that told me that I shouldn't have had that tier as now I'm paying for it dearly (It's going to cost me dozens of hours to fulfill for that one person. I'd rather just hand 'em $5 or heck $10 and I'd still be saving money). I had some other prizes like that. I could have dumped that and a couple other rewards and still been very generous and now not quite as slammed as I am. (But note that you are likely taking on a full time job to fulfill your promises as a Creator, so bear that in mind when you run most Kickstarter Campaigns - not just during the campaign, but after).
Now, the tiers above that $5 tier also got that reward as part of theirs, but since I'd been generous anyway, I could have just left it out. The best/easiest rewards to give away are intangible (pdfs, wallpapers, ebooks, etc.), but it's hard to keep it to just intangible and I see way too many campaigns not only not being generous, but charging outlandish amounts just for a thanks (no offense, but A thank you card by an unknown author/inventor, filmmaker, whatever, isn't worth much. Way too many campaigns are asking for serious money and aren't giving much of anything in return). You want to give more to your Backers who are having faith in you, than what you will later sell the product for (sounds obvious, but I'm seeing people charging $30 to Backers what they plan to sell on the market for $20. That sort of thing is cutting off your own leg. It's foolishness - you want to truly reward your backers and not over value intangibles like "Credit on the website" and "My eternal gratitude"!
Anyway, what I could have done, if a large number of people starting backing, was then toss in that $5 tier, if needed. I could have sweetened the pot later by adding more rewards to a particular reward tier or add some small goodies in, rather than promise up front, assuming I'd need a particular tier.
I knew I could add surprise tiers and goodies later (and if fact I did - I offered 2 more stories than I originally promised). Again, you need to be careful there too. While I think adding one of those stories helped me, the other didn't and once again I ended up committing myself to more hours than I needed too. It's always hard to judge what's going to bring you backers, but you should be very, very careful.
Lastly for now, You don't want to just use Google+ and Twitter (or Facebook for that matter) to blanket spam everyone. You also want to be active on those sites, investing in the lives of others - getting to know them better, backing other people's projects and giving free advertisement for projects you think are worthy. I gave a lot of Creators free advertising when I could be advertising my own campaign (and yeah, I did that too). But I was a good guy and helped out others (something we all should be doing). I didn't do that to get the Creators to back me, nor did I ask them to, but some of them did see my generosity and backed me and that was very cool!
We need to be standing together as best we can to help each other out. But please, before you go asking people for help or money, take the time to do your homework. I'm seeing way too many Creators making very obviously bad choices for their campaigns - presenting themselves unprofessionally, making poor choices on Reward values, etc.
You should have several people see and give feedback on your Kickstarter page and video long before you ever run your campaign. Take it slow - don't be in a hurry as it just leads to failure, unless you are uber lucky. Take the time to get the feedback you need on everything, to spread the word (I recommend a solid year for that alone, but I know most "can't wait" that long), and time to dot your i's and cross your t's.
