Volunteers want to participate in projects that deliver meaningful results for communities. And seeing the impact your non-profit has on society will spur prospects to volunteer and partake in your cause. In the digital world, we live in, what better way to show how you have been transforming society than with social media ads? You can run Facebook ads targeted at your locality (or the location where you seek volunteers) detailing the transformations your non-profit has triggered in societies. These can be traffic-based ads with you aiming to land as many people on your landing page, where you extensively curate pictures and videos from your previous volunteer campaigns. This is for visual documentation to enhance trust and boost your credibility. For ad creative, you can either use results your previous projects generated or video testimonials from previous volunteers about how rewarding their experience volunteering with your nonprofit was.
