It depends on how much you're raising, how big your audience is online, and how relatable your project, product, or organization is. We recommend spending at least $50 a promotion, and doing it once a week during your campaign. So a 30-day campaign would have a minimal budget of $200 (4 X $50), a 40-day $250 (5 X $50), and a 60-day $300 (6 X $50).
However, that is a minimum recommendation. Most crowdfunding platforms recommend spending at least $1,500 for paid promotion over the course of your campaign. The more you spend, the more you can make.
With Storyblaster's One-Click Paid promotion, you can see the results of your promotions, and if we're making more for you in contributions than the amount you're spending, keep promoting! Simple as that.
