It seemed unethical to me, and I figured that the engines would pick up on this and bring it to an abrupt halt. And they have. They want pages with content. So much for all those doorway pages. It was a big waste of time and effort.
Most web sites consist of several pages.
Hopefully, each page covers a specific, but related topic. And, hopefully, there is already a navigational system in place, where each page links to all other pages. This is a must. If you have a site, for example, on Internet Marketing, you already know that this subject encompasses many topics. Each of those topics deserves its own page.
