Nielsen is rolling out flagship digital advertising measurement solution in six Asian markets – Japan, Indonesia, Singapore, Philippines, Thailand and Malaysia.

The six new markets using the Nielsen system bring the Asia total to seven; China was one of the new system’s original 12 markets.

The commercial service is already up and running in Japan, Indonesia and Singapore. Philippines, Thailand and Malaysia will follow in the coming months.

The U.S.-based audience measurement agency says the Digital Ad Ratings “advances digital advertising accountability”. The system uses a patented process combining Nielsen’s online data with aggregated, anonymous demographic information from third-party data providers.
