Google Grants is a unique in-kind donation program awarding free AdWords advertising to select charitable organizations. We support organizations sharing our philosophy of community service to help the world in areas such as science and technology, education, global public health, the environment, youth advocacy, and the arts.

The Google Grants program empowers over 4,000 organizations to achieve their goals by helping them promote their websites via advertising on Google. Google ads appear when users search on Google. For example when you search for "world poverty" on Google, text ads related to world poverty appear on the right hand side. When you click on one of the ads, you are brought to the website being advertised.

Organizations that receive a Google Grant are awarded an in-kind online advertising account which can be used it in a variety of ways, including general outreach, fundraising activities, and recruitment of volunteers. Google Grants participants have found much success with the program. For example, the US Fund for UNICEF's e-commerce site, Shop UNICEF, experienced a 43 percent increase in sales over the previous year, while CoachArt – supporting children with life-threatening illnesses through art and athletics programs – has seen a 60 to 70 percent increase in volunteers.
