The Science of Giving: What Donors Want

Frequently Asked Questions

What is the Science of Giving?

It's Donorbox's set of ten principles for getting donors to give and keep giving. We built it from published research on donor behavior, and it covers two jobs: making donors feel confident in you, and taking the friction out of giving.

What are the ten principles?

Six are about confidence: transparency, credibility, congruence, security, impactful messaging and reciprocation. Four are about friction: attention, reduced cognitive load, easily repeated and accessibility. In plain terms, donors give when they trust you and when giving is easy, and these ten cover both.

Why do donors stop after their first gift?

Most of the time they just don't come back. About half of new donors never give a second time (Kim et al., 2021). The research links coming back to trust, credibility, satisfaction and how well an organization communicates (Roberson, 2015).

How fast should a donation page load?

Aim for under three seconds on a phone. Google's 2016 research found that 53% of mobile visits were abandoned when a page took longer than that (Google, "The Need for Mobile Speed"). The study looked at mobile sites in general, not donation pages, but donors are unlikely to be more patient.

How soon should you thank a donor?

As soon as you can. Only 39% of donors are thanked or recognized, and donors who were thanked said they would give 21% more next time (Merchant et al., 2010). The research doesn't name a deadline. Our advice is a personal thank you within 48 hours. The guide covers this under Reciprocation.

Is this research peer reviewed?

Not the framework itself. The ten principles are Donorbox's own work and haven't been through a journal's peer review. They're built on published academic studies, mostly from peer reviewed journals, and each claim links to its source so you can check it.

Do I need technical skills to use these 10 principles?

No. Every principle ends with a Do This Now list of small steps. Most are about wording, layout and follow up, so you don't need to code. A few, like page speed, may need a developer or your donation platform's support team.

How does this guide help me plan my campaign?

It includes a 6 step campaign plan and a 10 point checklist for testing your donation page before you launch.
