The Nivea brand advertising site features a very wizard for determining the type of logo file you should download depending on how the logo will be used. The visitor will answer questions about the purpose, application, and size needed. At the end of the process, a file is given to download. The questions are very easy to answer, and stepping the user through this process eliminates having to sift through a longer list of file types to determine the logo that would best suit the user's application.

1. User indicates the purpose for using the logo.
2. User indicates how the logo will be used&38212;in which type of application.
3. User indicates size of the logo.
4. System provides appropriate logo.
