I was doing a bit of research today for a term with few results. One site had 2 results so I hit the "More results from www.yyy.com" link. It came back with 8 results. The last of these entries has the odd bit.
Most results have something like this as their last line: "www.yyy.org/blah/blah.html - 15k - Cached - Similar pages"
But the last result has: "www.yyy.org/blah/blah2.html - 7k - Supplemental Result - Cached - Similar pages"
Anyone else seen this before?
This is purely a guess, but could this be a page that was found by freshbot but hasn't been fully incorporated into the google databases yet?
(I'd be happy to sticky the particulars of the search)
>I have also seen examples that lead me to believe that supplemental results are orphaned pages that no longer have any backlinks.
I have seen the exact same thing. Including with a site of mine, where a bunch of content where the link to it was removed ages ago is back in Google because Googlebot apparently has the memory of an elephant. I suspect Google is trying to beat the competition for the most pages indexed by indexing things the competition can't find that Googlebot is aware of.
I just did a site:domain.com -asdf (for my domain) and got a "Supplemental Result" of a page that has not existed since Febuary 2002. I then did a search for the exact title of that page and it brought up a bunch of my PR0 domains that are alternate spellings that I have for my site. (They were also listed as "Supplemental Result") I did not think those were even in Google. They are all pages that do not exist and have not existed since Febuary.
