The key concept to grasp is that your content can be delivered via the internet to a variety of widely available and utilized platforms. The internet no longer equals a collection of web sites. Almost any appliance or electronic device, these days, is "connected to the cloud." It is a simple matter of understanding the context in which your services might be consumed across these cloud-based service platforms. First, you need to ask, which platforms are widely utilized by my target audience? Next, you'll investigate the trends in usage patterns. What are your end-users doing on their iPhones? Are they utilizing competitor services? Which competitor services? Etc. etc.
Ultimately, when planning a digital tactic, enhancement, or offering, the starting point does not always have to be your web site. The truth, as always, lies in understanding and anticipating your end-users' behavior. This understanding is the Rosetta Stone for developing and deploying successful digital tactics.
