You put a lot of work into creating your brand guidelines. Make sure people keep the details straight and the execution consistent with a web style guide. You need one because so many vendors are involved in your digital presence. The vendor that creates and manages your website may be different from the vendor that manages your digital ads, mobile app or even interactive kiosks. But your customers don't need or care to know that. They just want to know they can trust you, and that comes down to being consistent across everything you deliver.
