How you read depends on when and why you read. When you read to find information in a reference book, you probably just scan the words. You look for what you need. However, when you read for fun in your free time, you read differently. You probably focus on the text more closely and read more slowly. The same situations apply online. Typically, people use website and online material as sources of information. Not very many people spend time reading online just for pleasure. In essence, this means that very few people are reading every word that appears on their computer screens. Rather, people are scanning web pages for data that is useful or interesting to them.
