This document outlines the ads, banners and editorial, including examples, required for your affiliate programme. It is recommended that you read through this guide and provide as much creative content as possible to assist Affiliates in promoting your programme.


Ads/Banners are a great way of getting brand recognition and we recommend that a broad selection of banner sizes and creative treatments are provided to give affiliates the widest possible choice. Having a banner that fits a niche on an affiliate’s page could be the difference between them running your campaign or another merchants.
