It's been my understanding that a web page without any links TO it, although indexable by the SE's, will get a LOWER listing than the same page with links TO it. i.e., doorway pages. This then is the reason to somehow have a link to your doorway pages. Don't know where or when I heard this, though it may have been from the apparently deceased Max. She did a fair amount of work on my site and we talked extensively. As did Jim and I a little over a year ago.
