Sales pages can be short or long depending on your product or service and the amount of information it requires to explain the value to users. I design user-centered sales landing pages that convert.
My favorite IDE (Integrated Development Environment) and web design platform is hands down Adobe Dreamweaver. Today’s user expects a lot out of your website; it has to load in under two seconds globally, expose the desired service, and be compatible to view on a myriad of platforms and devices, from a desktop computer to a newly released tablet or the latest iPhone. Most importantly, it must resonate with your audience's needs.
