John Lewis and Cadbury, among the first brands to advertise on Instagram in the U.K., are happy with the results. John Lewis’ campaign involved a blog-style photo shoot showing off the high-end ranges of its clothes. According to figures provided by Instagram, compiled using Nielsen’s brand effects suite, the campaign resulted in greater purchase intent for users aged between 25 and 34 years old. Purchase intent saw a 14-point lift, while ad recall was up by 10 points.
