A review is a written analysis and judgement of a product or service. Consumers often use reviews when deciding whether to engage or buy a product or service, making them a valuable tool for organisations.

In the tech world, reviews are widely circulated across a variety of consumer sites, and often when new technology arises, companies want reviewers to analyse and promote the products to their audience. Often reviewers have specialised expertise in the field they review, so consumers know they are getting an informed and professional opinion.
