Explain some details about doorway pages?

Webmasters are sometimes told to submit “bridge” pages or “doorway” pages to search engines to improve their traffic. Doorway pages are created to do well for particular phrases. They are also known as portal pages, jump pages, gateway pages, entry pages, and by other names as well.

Doorway pages are defined as low-quality pages (or groups of pages, or entire websites) optimized to rank well for specific keywords that act as a door between users and content. Characteristically, they offer little value to visitors and serve the sole purpose of boosting SEO value.

Doorways 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. They can also lead users to intermediate pages that are not as useful as the final destination.

Here are some examples of doorways:

• Having multiple domain names or pages targeted at specific regions or cities that funnel users to one page
• Pages generated to funnel visitors into the actual usable or relevant portion of your site(s)
• Substantially similar pages that are closer to search results than a clearly defined, browseable hierarchy

Doorway pages are Black Hat SEO techniques in which users is redirected to similar pages when inserted a particular phrase.
