What is a gateway page?

[codiant]

A gateway page, also known as a doorway page, are sites or pages created to rank highly for specific search queries. They are bad for users because they can lead to multiple similar pages in user search results, where each result ends up taking the user to essentially the same destination.

A Doorway page is a page on your website which has been created to rank for specific search queries. Often times, website owners would create a lot of pages, trying to rank for a specific keyword or phrase on search results. Typically, doorway pages are just a "Doorway" to the main content and is not at all useful to users. Sometimes, this tactic involves redirection to another page, and when the user clicks on it, the meta refreshes and there is a very quick redirect to another page. However, Google's been countering these techniques pretty well so far.
