This is even stranger. Not only is the well established 11 year site home page off the radar, but a sister site, which I never got around to building ranks #6
LeftWidgets This is the 11 year old site.
Search for "widget stats" and the home page was #1 for over 4000 days. Now gone, replaced by a forum section which is now #1
RightWidgets This is a domain I bough 5 years ago. It's one page which just says what the site will be about. I have never got around to starting this project so it's more of a holding page, an under construction page.
Search for "widget stats" and this UC page is # SIX
Not only is one of my useless sites ranking infinitely better than the authority site, but this useless site is ranking way better than my competitors. So I and them are equally cheesed off.
It will be interesting to see WMT reports in a few days.
