Google has launched an AdSense feature that will allow AdSense publishers to donate their earnings to Haiti earthquake relief efforts.

“We’re currently accepting donations from AdSense publishers with an unpaid account balance through January 31, 2010,” says Google’s Elizabeth Ferdon. “To see what your unpaid account balance is, please visit the ‘Payment History’ page within your account. Your January earnings will post in the next few days, so feel free to refer to your ‘Advanced Reports’ page for an earnings estimate until those are finalized.”

Publishers can either donate a portion or all of their unpaid balances starting the end of January. “As you may expect, there are certain restrictions to donating, and all our normal policies still apply — so even if you’re donating, please don’t ask others to click on your ads in order to increase your earnings,” says Ferdon.

Google will not process donation requests from publishers whose request to donate more than their unpaid balance through January 31, or if they are subject to tax-withholding, their account has been disabled for invalid activity or other violations of terms and conditions, or if their accounts display the messages: “please submit your tax information”, “please enter your PIN”, or “please verify your phone number”.

Partners in Health is the organization that will receive the donations. They will go to provide medical aid.
