Let your potential funders know how your product or business idea can benefit them. Share who you are, where the project idea came from, what you're planning to do, what your budget is and why you're passionate about it. This shows that you've actually put some thought into the idea, which helps prove the legitimacy and credibility of your project.
Communicating your story through visual imagery is of particular importance. Make sure to create a great looking project-header image as well as a compelling video. Video is particularly important, and can even make or break your project.
Ensure that your video is high quality and professional. Most campaigns that do well on Crowdfunding platforms have great looking videos. Make it engaging and fun to watch, and don't cut corners with the production.
