In our everyday life, we use search engine to find information. According to Agostini, most websites receive traffic from search engines through two types of keywords. Generic category keywords which defined as general word we use such as green tee shirts and branded keyword which search by brand name. In his experiment on Yandex.ru, search result came out differently depending on letters and language. Even miss typed words will display different result. Most sites use these terms and modify to their website to get more traffic. Agostini argues that this method used by search engine can be misleading and effective at the same time. So we must be able to aware of it.
