To take the authority theory for ranking across multiple pages further: I decided to do a few blind searches to see if I could find what I was searching for, the first term pulled up myself at #1, then the "house #*$!" site at #2. My site delivered EXACTLY the deep content the search should have produced, but the assumed "authority" produced ABSOLUTELY ZERO useful content related to the search.
However, the "house #*$!" page did contain parts of the search term, but in a very spammy volume. If you look at the comments on these sites, they are simply single key phrases by the hundreds, if not THOUSANDS.
This is where the Penguin should step in...
