The Holmes Report has launched a dedicated microsite for its Global Rankings and Report Card analysis of the public relations industry.

In addition to its definitive ranking of the 250 largest PR firms in the world, the Global Rankings 2011 site also features analysis of the performance of 23 global PR agency networks, and research into attitudes and trends from around the world.

The site also includes market profiles of North America, Europe and Asia-Pacific, investigating local market conditions and revealing the firms that are leading growth.

Included for the first time is social media analysis of the 23 global networks, using Sociagility's proprietary PRINT Index methodology.
