Top 10 lists of most popular search engines on the web.
1. Google 
Enables users to search the Web, Usenet, and images and many more. When you visit www.google.com or one of more than 150 other Google domains, you can find information in many different languages (and translate between them), check stock quotes and sports scores, find news headlines and look up the address of your local post office or grocery store. You can also find images, videos, maps, patents and much more. With universal search technology, you can often find all of these things combined in one query. Of course, there is a lot of information in the world that is not yet online, so we're also working to get more of it digitized, such as in Google Books or the Google News Archive. We also know that whenever you search the web you want it to be as fast as possible, with all your favorite websites at your fingertips, so we offer software like Google Toolbar and Google Chrome to help you browse the web quickly and easily.
2. Bing.com (formerly Live Search, Windows Live Search, and MSN Search) is the current web search engine (advertised as a "decision engine") from Microsoft. Notable changes include the listing of search suggestions in real time as queries are entered and a list of related searches (called "Explorer pane" on the left side of search results) based on semantic technology from Powerset, which Microsoft purchased in 2008. Bing also includes the ability to Save & Share search histories via Windows Live SkyDrive, Facebook and email.
3. Yahoo! provides content including the latest news, entertainment, and sports information, and gives users quick access to other Yahoo! services like Yahoo! Mail, Yahoo! Maps, Yahoo! Finance, Yahoo! Groups and Yahoo! Messenger. The majority of the product offerings are available globally in more than 20 languages.
4. Ask.com Offers search for web sites, images, news, blogs, video, maps and directions, local search and shopping.
5. Answers.com is the place where reference information and Q&A content come together to deliver the best answers on the Internet. It's built upon a combination of two answering styles: ReferenceAnswers is a one-stop shop that aggregates dictionaries, encyclopedias, atlases and more, offering millions of topics available for fast-fact lookup as well as deep research. WikiAnswers is an advanced Q&A platform powered by the collaborative efforts of a global knowledge community... with a wiki-twist.
6. AOL is AOL's customizable portal experience on the Web, providing top news, movies, music, weather, finance, sports, horoscopes, an RSS Feed Reader and more; quick and easy access to AOL Mail, AIM Instant Messenger, MapQuest, TMZ and Bebo; as well as convenient access to third party services such as eBay, Gmail and Yahoo Mail, Twitter, Facebook and MySpace.
7. GO.com (also known as The Go Network) is a web portal first launched by Jeff Gold, and now operated by the Walt Disney Internet Group, which is a part of The Walt Disney Company. The portal includes content from ABC News, ESPN, and FamilyFun.com, all of which are associated with Disney and are hosted under a .go.com name. Along with TimeWarner's Pathfinder.com, Go.com proved to be an expensive failure for its parent company, as web users preferred to use search engines to access content directly, rather than start at a top-level corporate portal.
8. AltaVista is a leading provider of search services and technology. AltaVista continues to advance Internet search with new technologies and features designed to improve the search experience for consumers. Based in Sunnyvale, Calif., AltaVista has a rich history of innovation embodied in 61 search-related patents.
9. Dogpile.com aggregates the most relevant searches from Google, Yahoo!, Bing, and Ask and delivers them to you in a convenient search package. With Dogpile, you get the best from the big dogs without all the mess.
10. WebCrawler brings users the top search results from Google, Yahoo!, Bing, Ask and other popular search engines. WebCrawler also provides multimedia results, including images, video, news, and local information.
The Top 100 Alternative Search Engines
Ask anyone which search engine they use to find information on the Internet and they will almost certainly reply: "Google." Look a little further, and market research shows that people actually use four main search engines for 99.99% of their searches: Google, Yahoo!, MSN, and Ask.com (in that order). But in my travels as a Search Engine Optimizer (SEO), I have discovered that in that .01% lies a vast multitude of the most innovative and creative search engines you have never seen. So many, in fact, that I have had to limit my list of the very best ones to a mere 100. Read more...
