A look at some of the dirty tricks used to get web pages into search engine listings they would otherwise not appear in (with the sort of drily humorous photos/captions that have been appearing in many recent BBC stories):

Webmasters make thousands of these pages that differ enough to make the indexer think they are unique, and all point to the one that the webmaster wants you to see... Often these "bridge" pages are "cloaked" so you never see it but get bounced to another - usually the main page that the hidden one points to.

Not surprisingly, a lot of fingers point at the porn industry, which is not known for playing by the rules.
