Case Study: charity: water achieves higher donation sizes and more campaign sign-ups with Optimizely

How charity water boosts donation size

charity: water, the nonprofit focused on funding clean water projects, wanted to increase online fundraising and improve donor engagement. Using Optimizely’s Web Experimentation product, the team tested donation page defaults, matching offers, and campaign sign-up flows to see what would drive more giving without hurting conversion.

Optimizely helped charity: water find that a $60 pre-fill increased average donation size, a holiday matching offer lifted average donations by 30%, and a shorter campaign flow boosted “Create Campaign” clicks by 34%. Overall, Optimizely’s experimentation has helped charity: water raise millions more online while building a stronger, more sustainable donor base.
