An expert review is an activity that a designer can perform to conduct an independent audit of a

current website. An expert review is a method of evaluating the usability and user experience of a

website by applying established principles, guidelines, and heuristics. An expert review can help

identify the strengths and weaknesses of a website, as well as provide recommendations for

improvement. An expert review can be done by one or more experts, who can be internal or external

to the organization. An expert review can be done at any stage of the design process, but it is

especially useful before launching a new or redesigned website, or when there is a need to assess

the current state of a website. [UX Designer Certification Prep: User Research], [UX Designer

Card sorting, task analysis, and prototype testing are not activities that a designer can perform to

conduct an independent audit of a current website. Card sorting is a method of organizing and

labeling information for a website, based on how users group and name the content. Task analysis is

a method of understanding and documenting the goals, tasks, and steps that users perform on a

website. Prototype testing is a method of evaluating the functionality and usability of a website by

having users interact with a mock-up or a simulation of the website. These methods are useful for

creating or improving a website, but they are not suitable for auditing a website without involving

the users. [UX Designer Certification Prep: User Research], [UX Designer Certification Prep: User
