In the last half of October, a number of my pages that had never done well in the searches started pulling enormous traffic. The pattern seems to be that my longer pages which are very dense on keywords did well.
Pages that previously did well including some that had no true SEO structure, low keyword density, and were somewhat short, seem to be doing slightly worse.
Any thoughts?
Another possible explanation has to do with some "deep links" that I've put out there, like on this blog.....
