Concept Feedback is a website review community with over 5,000 web designers and developers, marketers and entrepreneurs. Once a website is posted on Concept Feedback, members are invited to provide reviews. On average, a concept receives 12 or more unique reviews, while some can generate as many as 100. Because of the nature of the community, feedback can cover a variety of topics, including design, usability, content and strategy. Concept Feedback is best for getting design-related feedback from a wide audience and can be used at all stages of development.
