Some search engines get their results by turning to third-party "search providers" to "power" their listings. To make matters more confusing, these search providers may run their own search engine sites, as well.
The chart below explains who the major providers are. Knowing who powers whom is helpful for those who are wondering which companies are "winning" in the competitive market of powering search. Information is for users visiting the US/global version of the search engines listed, unless otherwise noted.
This information is also helpful to webmasters and search engine marketers trying to understand where to get listed. If this is your goal, also read the Search Engine Results Chart. That table is more oriented for those looking to get listed with different search engines. It shows all the major search engines and how they get their listings, with links leading to submission help from Search Engine Watch's Essentials Of Search Engine Submission guide.
The key for the chart is shown first, then the chart itself comes further below, so there's enough width to display it properly. To learn more about a particular search engine or search provider, just click on its name. You'll be taken to the appropriate section of Search Engine Watch's Major Search Engines page.

- Light Blue: search engines with 0.5 percent share or greater share.

Main: Indicates that a search provider provides the "main" editorial results to a particular search engine, the most dominant listings that will be seen.

AOL renewed its deal with Google in October 2003 but did not specify exactly how long the partnership would last. Date shown is the minimum length estimated by Search Engine Watch, based on past deals between the two companies.
Lycos has an existing contract with Yahoo-owned Overture for paid results running through May 2006. However, the company switched to Google in November 2003 due to a contract dispute. Google paid results also appear on Lycos-owned HotBot.com. For more, see coverage on the dispute from InternetNews.com, News.com and CBS MarketWatch. Lycos also runs its own paid listings in addition to those from Google on Lycos and HotBot. See Terra Lycos To Launch Paid Placement Network for more about this. A deal struck for backup results from the now Yahoo-owned AllTheWeb site was to expire on December 31, 2003. There's been no news of any renewal. The AllTheWeb search engine no longer uses its own technology. Instead, Lycos uses Yahoo main results (and flags these as being from Inktomi).
Yahoo main results come from its own crawler-technology. These results often look different on sites that Yahoo powers, such as MSN and Lycos, when compared to the same search at Yahoo itself. This is because Yahoo operates its own unique ranking algorithm on its own site. Yahoo paid results come from the Overture paid placement listings service that it owns. The Yahoo-owned Inktomi search engine no longer operates, though Yahoo-partner Lycos may still say that results are coming from Inktomi.
