Thanks for the tip 2_much. I found at least one keyword that is so good that I am considering targeting it. I just have trouble finding acceptable ways to include bluewidget when it should be blue widget.
I wonder if AOL will ever start to include “did you mean” blue widget when people type bluewidget like Google and others do. After all, the AOL users could probably use a bit more help than the Google searchers.
I accidentally typed a run-on into Google yesterday, and that smart little engine told me it was going to split my words...didn't even give me a choice. But it's clear from my logs that many SEs have the linguistics programming to handle this, whether they inform the user or not.
Makes me wonder what will happen with intentionally optimized run-ons. One way to get them in a page without looking too weird is to use "CamelCase".
