Doorway pages are web pages that are created for spamdexing, this is, for spamming the index of a search engine by inserting results for particular phrases with the purpose of sending you to a different page. They are also known as bridge pages, portal pages, zebra pages (a humorous arbitrary coinage by Jill Whalen of High Rankings Advisor), jump pages, gateway pages, entry pages and by other names. Doorway pages that redirect visitors without their knowledge use some form of cloaking.

If you click through to a typical doorway page from a search engine results page, in most cases you will be redirected with a fast Meta refresh command to another page. Other forms of redirection include use of Javascript and server side redirection, either through the .htaccess file or from the server configuration file. Some doorway pages may be dynamic pages generated by scripting languages such as Perl and PHP.

Doorway pages are often easy to identify in that they have been designed primarily for search engines, 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.

Because many search engines give you a penalty for using the META refresh command, some doorway pages just trick you into clicking on a link to get you to the desired destination page, or they use Javascript for redirection.

More sophisticated doorway pages, called Content Rich Doorways, are designed to gain high placement in search results without using redirection. They incorporate at least a minimum amount of design and navigation similar to the rest of the site to provide a more human-friendly and natural appearance. Visitors are offered standard links as calls to action.

Landing pages are regularly misconstrued to equate to Doorway pages within the literature and should be avoided. The former are content rich pages to which traffic is directed to within the context of pay-per-click campaigns and to maximize SEO campaigns.

A content rich doorway page Must be constructed in a (SEF) Search engine friendly manner, otherwise it may be construed as search engine spam possibly resulting in the page being banned from the index for an undisclosed amount of time. Mined how you use you meta tags especially the keyword tag. Most search engines uses the keyword density to rank pages aside backlinks.
