They allow individuals to see key features, prices, and specifications in a clear format, making it easier to make informed decisions. Common examples include price comparison websites and product review platforms. These tools often include filters and sorting options, enabling users to narrow down their choices based on specific criteria, such as budget or desired features. By using comparison tools, consumers can save time and money while ensuring they select the best option for their needs.
