Why bother then? You need to use social media strategically to support your crowdfunding campaign. Here are a few tips to get social media to work for you:
#1 Diversity your posts
Don't just post your goal and progress toward it. Post photos of yourself training. Share why you care and why you are raising money. Post photos related to the cause that you're supporting.
#2 Thank your donors on Facebook
In all likelihood, a lot of your friends are part of larger social groups. One friend in a social group makes a donation to your cause, and it will inspire others in that network to give. By thanking your donor friend on Facebook you are not only honoring that person but you are reminding your other friends about your campaign.
#3 Don't be afraid to tag people
The reason why people don't give the first time they are asked is not because they don't want to give to your campaign. It's usually because they read the email at a bad time, saw it on their phone, or want to wait til payday to donate. If you tag people on Facebook you are reminding them to give in another way. I like to think of this as a stronger nudge and usually try other methods first to get a yes or no answer.
#4 Use Incentives
During my last campaign I promised everyone who gave a custom piece of digital art. I am still working on it (I haven't forgotten!!!) but when I do finish a piece, I post on Facebook and tag my friend. I started doing this during my campaign and believe that some people gave a gift because they were also curious about the art I'd create for them.
From my personal experience, the vast majority of donations I've received via crowdfunding have come from personal emails or in person asks. However, about 15% of my past donors gave in response to the Facebook posts. These were people I didn't ask via email in the first place.
Don't forget social media but also, don't rely on it to help you reach your goal. In marketing terms, a multi-channel approach is best!
