Since the devastating disaster in Haiti, companies and individuals are looking for creative ways to help. Several AdSense publishers asked via WebmasterWorld and Google AdSense Help if there are ways to donate their AdSense income.
Last Thursday, the Google AdSense blog announced a way to do just that. Google said, "you can donate a portion or all of your entire unpaid balance as of the end of January. Whether you have a balance of $0.10 or $100 in your account, we invite you to participate within the next week."
To do so, you need to fill out a donation form. The donation form, if you are logged into your AdSense account, will pre-fill your AdSense unique IDs.
