We approached Three UK and showcased the power of Google 360 Virtual Tours to their Head of Marketing and Web. They were so impressed that they trialled 10 stores to begin with. Within 2 months of seeing the retail 360 virtual tours go live on Google, they tracked retail footfall, website click and visits, spend per customer and other metrics.
All we can say (private NDA stuff!) is that they asked us to carry out 360s on each of their Three Mobile stores across the UK and Ireland as a result of the (successful!) pilot.
Three SEO Web team did a case study on their findings and submitted this on a Retail Awards where they went on to win 1st place, as a result of using modern technology in the retail space.
