Advantages of wireframe

1.They are relatively cheap to create. Even a whiteboard can be used to create them. Using wireframes, you can save time and the expense of creating possible unsuitable UI models.
2.You can give a wireframe to key users and they will quickly have a basic understanding of your intention. If something is wrong, it can be corrected instantly.
3. When you present a graphically designed home page prototype to users, their attention is focused on the style of the page — the logo used, the font type, and so on — instead of the structure of the page. Of course, later you must present them with the graphical design. But fi rst the structure should be grabbed.
4.A wireframe is also a good start for the fi nal web design, because it relays a lot of information about the intentions of key users that is useful to the experts who create the graphical design.
