Social Actions is an organization which aggregates actions from other social change related websites, and then provides searching and browsing of the list so that individuals can easily find ways to get involved with various causes and nonprofits. Just recently they have launched an AdWords-style widget that can be placed on a website which displays recommended social change actions and volunteer opportunities based on the content of surrounding page. All of these social change actions and campaigns are gathered from other websites such as Change.org, Idealist, Kiva, GlobalGiving, and many others.

Peter from the Social Actions blog explains how the widget works:

After you cut and paste the widget snippet code into your website, the widget automatically scans the content of each web page on which it appears and identifies the top three keywords for that page. The widget then searches for related campaigns on 20 social action platforms. It then automatically loads the top three campaigns for the keywords, with the option to discover more. As the content of your site changes, the widget checks to see if there are new keywords. As a result, your readers are always connected to fresh and relevant calls to action.
