But understanding how they relate to each
other is very difficult, and always changing.
Most of the major search engines are aligned with
another engine or two in some way, or share their
database results with other search engines.
By clicking on the following link, you can view a PDF document that outlines the complex relationship between all the major search engines.

As you can see from that document, obtaining top results in any search
engine means taking into account how they obtain
their results. This can make search engine
strategy quite complex.
For example, if you want to rank high in NineMSN, then you
may need to be listed in Yahoo (Overture), but not if Yahoo
(Overture) has no sites in it's directory relating to your product.
You could obtain a free listing in MSN, and if you were listed
at the top of their listings, you could end up on the front
page of NineMSN because they may have little or no results provided
by Yahoo (Overture). In this kind of scenario, you could obtain
a top page ranking in NineMSN at no cost!
The list of possible scenarios goes on and on, and your strategy
will depend on your particular product and market. The relationships
noted above can vary in different countries around the world.
