Recruiting new supporters and encouraging them to take part in campaigns and make donations is crucial for charities and non-profits. In this talk I will talk about how a few charities I have worked with recently, ShareAction, Positive Money and Refugee Action, have managed to achieve that using their WordPress websites. Through a mixture of strategic use of plugins and optimising the sites to encourage people to sign up or donate at the right time, I will go through a range of case studies and practical tips to show how other people can get similar results.
