Do you create pages, either on my server or somewhere else, that are not built into the navigation of my site?
Another common technique that some search engine optimization companies employ is the creation of "doorway pages." Since the term "doorway page" now has such a negative connotation in the industry, many search engine optimization companies have their own names for such pages: "gateway pages," "bridge pages," "targeted entry pages," "specialized content pages," and so on. Whatever they are called, such pages are rarely effective and also put websites at risk of penalization, as this is another tactic that violates the terms of service of every major engine. If your potential search engine optimization company does not give you a definitive "no" to the above question, you may want to look elsewhere.
