Years ago I wrote a page about Baggerseen um Karlsruhe and put it online. The page gets quite some hits (around 30 a day). When you now google after Baggerseen, Google (DE) lists it on the first page (first ten of about 18000 entries).
Now, common knowledge says, that Google ranks pages higher that many links point to.
But when I enter 'link:www.pilhuhn.de/hwr/baggersee.html', Google says that no other page links to this page (which at least is not completely true).
So this entry is also a test if Google will in future list the contained link or not.
