User interface design

The "User interface design" is very important in the SEO world. if the SEO company gets the traffic to the site, the "User interface design" will keep the clients or make the leave the web site. The user interface design is based on:

• User analysis - analysis of the potential users.
  The user interface design needs to answer:
  • What does the user want the web site to do?
  • What would be the web sites normal workflow?
  • How savvy is the user and what similar systems did the user already use?
  • What interface look and feel would appeal to the user?
• Information architecture - the flow of the web site.
• Prototyping - development of wireframes.
• Usability testing - testing of the prototypes on actual users.
• Graphic Interface design - actual look and feel design of the graphical user interface (GUI.) It may be based on the findings developed during the usability testing if usability is unpredictable, or based on communication objectives and styles that would appeal to the user. In rare cases, the graphics may drive the prototyping, depending on the importance of visual form versus function. If the interface requires multiple skins, there may be multiple interface designs for one control panel, functional feature or widget. This phase is often a collaborative effort between a graphic designer and a user interface designer, or handled by one who is proficient in both disciplines.
