Not really answering what you are asking, but the “related” search is tremendously helpful.
related:http://www.yahoo.com or whatever
If among a page’s related sites (aka “similar pages”) you find drastically off-topic or really pukey sites, this is a warning sign. Sometimes it just means someone who links to that page also links to crap… in other words it isn’t the fault of the page you are looking at… but this is a very helpful way to check out how Google is perceiving a page.
