What are doorway pages?

A doorway page is a page that is optimized to rank well on the search engines. Each search engine has it’s own unique ranking algorithms (formulas used to determine the relevancy of a page to a given search term). Since every engine’s algorithms differ, it is almost impossible to design one page that ranks well in all or even most of the search engines. This is why doorway pages are so important. A doorway page can be any existing page on your site or it can be a page that you create specifically for this purpose. A doorway page has no special look to it. It is simply an alternate entrance to your site that has the right words in the right frequencies, positions, and tags.
The design of the page is very important. A well designed doorway page blends into the rest of your site seamlessly. It also has relevant content targeted toward the key term. Each doorway page’s content should vary somewhat with the key term. Ideally the doorway page is not just a fluff page but rather an informative, eye catching, relevant page that describes your product or service.
