When someone creates some pages stuffed with certain keywords and content to get ranked high for some particular keyword/s, and when a user visits that page, it redirects that user to some other website. These kind of pages work as doorway pages for those websites to get traffic. This is an unethical practice, so do not try this.
Doorway pages are also called landing pages, Where visitors land for the first time and they are redirected to money page or sales page..
Doorway pages are often easy to identify in that they have been designed development primarily for search engines ranking, not for human beings. Sometimes a doorway page is copied from another high ranking page, but this is likely to cause the search engine to detect the page as a duplicate and exclude it from the search engine listings.

Doorway pages are simple HTML pages that are customized to a few particular keywords or phrases, and they are programmed to be visible only by specific search engines and their spiders. The purpose of these doorway pages is to trick the search engines into giving these sites higher rankings; this sounds okay until you realize that they are not static destinations. Instead, doorway pages are specifically aimed towards search engine spiders - once a searcher lands on a doorway page, they are instantly redirected to the "real" website.
