We’ve been exploring how PR consultancies can use social media to generate leads, and ultimately new business. An agency’s Facebook Page represents a pool of potential prospects – but it will only work for the business if its fans are properly engaged. We decided to look at the top PR agencies to see which are doing the best job of engaging their UK fans on Facebook. We ignored any that operate global Facebook Pages only, as their worldwide fanbases would skew the results; besides, these agencies are unlikely to be using these Pages to generate UK business. Then we tracked the number of fans of each agency, along with (equally important) metrics about activity on the Page – the number of posts, Likes and comments. (Read more about our Methodology here).
