Kickstarter published a blog post last July saying what their staff looks at when choosing a project to be featured on their front page. They don’t say that you must attract their attention (something that will probably be related to the amount of funding you receive at the start or the amount of media attention your project grabs), but rather they focus on the editorial guidelines your project page should follow to be featured.
First and foremost, your project should be remarkable. A great talent, a great piece of art or a breakthrough technology is a must. It must be shareable, be attractive and be polished.
Then, the editorial guidelines go along a line that serves well most internet projects. You shouldn’t hype your project. Don’t use words like “best”, “largest” and so on. You should say what your project is about and be concise in the first few paragraphs, so users don’t waste their time reading about it.
Images are important as well. You should use great images, free of any badges or offers. A clean image or a few of them will influence their staff.
It helps your project if you decide to use other high quality media, such as audio, video and additional images. Display them in a beautiful manner in the page, professionally produced. That will not only help you with the staff, it will also make the page more shareable. Focus on showing your rewards, on showing pictures of them or any other media about them. People have to know how their money will be used.
They also state that their audience is English-speaking, so that is the language you should use in your projects. Make sure there are not any typos and your pieces are well written.
Last, don’t spam, either by email or on social networks. Spamming is against Kickstarter guidelines.
