This page exists as an experiment in where search engines are looking to determine page content. As an often heated topic, SEO's will say things like "Google doesn't look at meta keywords". Unfortunately, most never do the research to prove them wrong, and that's exactly why this page is here.
This page hides garbage words in these locations (such as weasidoogoo), where zero competition exists, and after adequate time is given for search engines to index, checking which engines have indexed this information. Choosing 'view source' on this page should reveal all such test words so that you can test their rankings yourself.
