In existence for over 150 years, Pan Macmillan UK is one of the largest general book publishers in the UK and, as a part of the Macmillan Group, operates in over 70 countries worldwide. The first goal of the site was to increase the conversion rate, specifically the number of visitors buying books online. There was also an emphasis placed on site visitor engagement via participating in the blog, reading book extracts or learning about the authors. The website integrates with Twitter and Facebook as well as other third-party feeds featured on the website. Kentico’s E-commerce functionality is used extensively, with over 12,000 SKUs. This is possible with the help of Kentico EMS features, such as A/B Testing, MVT Testing and Content Personalisation. The website is hosted in a load-balanced, scalable Microsoft Azure environment, giving the client the peace of mind that they can cope with large spikes in website traffic.
