Recma's Compitches reports aims to rank media agencies based on their level of competitiveness in pitches in 2011 and over the past three years. The report ranks pitches worth more than US$2 million and identifies key pitches as worth more than US$25 million.
The report is based on a weighted, country-by-country ranking, and key international pitches are reported as "other pitches" if the involvement of local agencies are low.
In Asia-Pacific, China receives a weighting of six; Australia and India are each weighted three, while Singapore, Malaysia, Thailand, the Philippines, Indonesia, Vietnam, Hong Kong, and Taiwan each weighted one.
For the Greater China rankings (China, Hong Kong and Taiwan), Carat tops the list, followed by OMD and IPG Mediabrands' UM.
In Southeast Asia, Maxus and Mediacom are tied for top spot, followed by OMD.
Initiative, OMD and Zenith Optimedia jointly hold the top three spots for India and in Australia, Maxus and Mediacom are tied for top place, followed by Mindshare.
