Keywords or Key Words: Search Query Modification

I have been noticing with Google recently that if you search for something like seobook video that Google pulls in results for SEO Book video as well. They may have been doing this for a while, but if so it seems like it recently got more aggressive. If you are banking on targeting an unpopular version of a keyword you may actually end up having to compete with some of the most authoritative pages ranking for the alternate more authoritative version.

This feature, spell correction, and toolbar search suggestions eat away at some of the easiest portions of the organic SEO arbitrage market by helping search engines consolidate language usage patterns as best they can.
