This document examines the differences between paging and scrolling as methods of presenting search results, and evaluates which is the best approach for users.
Web designers are constantly confronted with the problem of displaying large amounts of information in confined spaces. To deal with this designers usually have two options, either present the information on one long scrolling page or divide it into smaller amounts on multiple web pages.
