A few months ago, we reported about Microsoft adCenter's accreditation program called, adExcellence.
Microsoft adExcellence announces 'the Microsoft adCenter accreditation program has launched an invitation-only pilot for US customers. If you are a current adCenter customer and would like an opportunity to participate in the pilot, please complete the form below. We are collecting this information to help us with the participation process. You will be invited via e-mail should you have the opportunity to participate within this pilot.'
Currently, this program is available only for customers in the US.
