Using social followers to power ASB's home lending business.
This case study is part of the #IPASocialWorks initiative which brings together the IPA, The Marketing Society and MRS with sponsorship from Facebook, LinkedIn and Twitter, to identify good practice in social media effectiveness and measurement.
