There are quite a number of more important search engines that use Third-party "search feeds" to gain more search results, thereby improving their own search capabilities. But since these search engines may run their own search engine sites, it is hard for users to find them even if they use third-party search results. The following diagram in

illustrates "who is the primary provider". With a look at the relationships between search engines, you can see who the real winners are in the highly competitive marketplace. For webmasters and search engine market investors, they can clearly know which search engines are the first choice for their site. Search engines: By "search hours" in order: more than 5 million search hours per month in the first search engine, with an orange background logo. (collaboration with this type of search engine is much more important than other providers); The search engine uses a light orange logo between 2 million and 5 million search hours per month, and a search engine with a light blue logo for more than 200,000 search hours; Gray means that the number of hours searched is not very high But it is recognized by many searchers as a better search engine.

Main (provides the main result): Indicates that a particular search engine uses a third provider's editorial results for its "primary" search results.

Paid for: Indicates that the third provider provides a paid service for a search engine.

Fallback (fallback provision): Indicates that a particular search engine uses a third provider's editorial results for its "fallback" search result, that is, only if the search engine's main results do not match the query requirements correctly, the results of this "fallback" third party are used.

Optional (optional): Indicates that a particular search engine uses a third provider's editing results for its "optional" search results, that is, the result may appear in its own search results, or in other ways. Generally the quality of this information is not very high.

Date (month/day/year): Indicates the deadline for a particular partnership. For example, LookSmart and MSN, LookSmart to MSN to provide its catalog results, the service date until December 3, 2003. And Google's cooperation with Aol,yahoo and Netscape only announces that its partnership will remain "for years" without giving the exact time. The general partnership is at least two years old, so the "2004+" you see in the table below is the minimum estimated cutoff time.
