I just received a newsletter that had something like this in it "Register “KEYWORD RICH” domain names that are going to help skyrocket your search engine rankings! "
It was talking about registering very long domain names.
Most, if not all search engines check if the keyword is CONTAINED in the meta tags, page, and URL, not if $keyword=$url or similar statements. The long domain names are as of now, supposedly not accepted by Yahoo, which is a big thumbs-down.
