This is a pretty good discussion subject, specially for this sub. I plan on running a Kickstarter later this year, and this are my basic ideas on how to do it.

• Show your product or a prototype working right off the bat.

• This goes without saying, but know basic english before writing your campaign.

• Use images and videos to populate your page, don't make walls of text trying to convince people to pledge.

• Be specific where and how the funds are going to be used.

• Offer a decent assortment of rewards for the true fans and believers of your project.

• Be transparent, keep updates regularly, communicate with your backers.

• Don't be afraid of criticism, and learn to accept it and even take them as advice, specially from backers - people want a good deal from their backing, so listening to them is your best bet.

• Don't be afraid of failure. If you don't reach the goal, don't just come back with a lower goal. Think of what were the reasons you failed and work upon them. And specially, don't give up, there's a reason you think your idea was a good one.
