Search engines are a boon for people seeking information on the Net. Especially people who would like to get some materials for teaching or writing or conducting research, these search engines come in very useful. So also for people from other fields like business and so on. Every search engine works on the basis of keywords. When specific keywords are typed into the given space, the search engine displays an entire list of websites for your perusal. The choice of search engine may vary. Most claim Google to be their favorite, a few go for AOL or Netscape. But the trend is now moving towards Yahoo as a better search engine. The reasons for this change are not far to find.
