Okay, so, if Google can't find enough "good" results from its regular database it uses the supplemental database. Yes?
Well, out of the top ten supplemental results I was No.5 - but I wasn't listed as supplemental. How can pages that don't exist rank above me? If I was under some penalty then surely I would be supplementaled too? Or is it that the non-existent pages of a more authorative sites such as BBC are better for Google users than my page?
