People on the German wikipedia noticed that a mirror site of the German wikipedia (wikipedia.t-st.de) has higher Google ratings than the "real" one, which was attributed to their use of <meta keywords=""> tags. (Supposedly, Google doesn't care about meta tags, but what do I know?)
I vaguely remember that (at least in Phase II) there were meta-keywords, generated from the title of the article and all wiki-links. Also, it had a meta "summary" tag from what the software thought was the first paragraph of the article.
Could we turn that on again? Might cost some bandwidth, but if it really gets us higher ratings, we should do this. Maybe for anonymous views only, since logged-in users probably don't care for meta tags...
