Google and Bing are the dominant players, making up the vast bulk of the web searches. But there are other niche search engines out there, one such example would be the privacy oriented search engine DuckDuckGo which I use for some of my searches.
Well there are many top search engines available on the web. But it is totally depend on country, like in China people are using Baidu and in few countries people are using Google, or Yahoo or Bing.
there are many search engine.such as yahoo ans,msn,google,bing,my web search etc.among these i think google is the best search engine.
