Dynamic Website: is one that changes or customizes content automatically and/or frequently based on certain criteria.

User experience "User experience" encompasses all aspects of the end-user's interaction with the company, its services, and its products. The first requirement for an exemplary user experience is to meet the exact needs of the customer, without fuss or bother. Next comes simplicity and elegance that produce products that are a joy to own, a joy to use. True user experience goes far beyond giving customers what they say they want, or providing checklist features. In order to achieve high-quality user experience in a company's offerings there must be a seamless merging of the services of multiple disciplines, including engineering, marketing, graphical and industrial design, and interface design. - Norman Nielsen Group 17

User experience The term "user experience" refers to a concept that places the end-user at the focal point of design and development efforts, as opposed to the system, its applications or its aesthetic value alone. It's based on the general concept of user-centered design. The user experience is primarily made up of a four factors: ü branding ü usability ü functionality ü content Independently, none of these factors makes for a positive user experience; however, taken together, these factors constitute the main ingredients for a website's success. 18

Branding includes all the aesthetic and design-related items within a Website. It entails the site's creative projection of the desired organizational image and message. Statements used to measure branding can include: § The site provides visitors with an engaging and memorable experience. § The visual impact of the site is consistent with the brand identity. § Graphics, collaterals and multimedia add value to the experience. § The site delivers on the perceived promise of the brand. § The site leverages the capabilities of the medium to enhance or extend the brand.

Functionality includes all the technical and 'behind the scenes' processes and applications. It entails the site's delivery of interactive services to all end users, and it's important to note that this sometimes means both the public as well as administrators.

Usability entails the general ease of use of all site components and features. Sub-topics beneath the usability banner can include navigation and accessibility. Statements used to measure usability might include: § The site prevents errors and helps the user recover from them. § Overall page weight is optimized for the main target audience. § The site helps its visitors accomplish common goals and tasks. § The site adheres to its own consistency and standards. § The site provides content for users with disabilities.
