Google’s Supplemental Index

By Deane Barker on August 30, 2003

Search Engine Showdown News: Google Tweaks Its Number to 3.3 Billion and Adds “Supplemental Results”: This is interesting.

“…I have suddenly found a few hits that Google labels as ‘Supplemental Result’ right before the cached link as in the last record on this search. I’m not sure what this ‘Supplemental Result’ is supposed to be, but the URL is a dead link. I certainly hope Google did not just boost its numbers by adding a bunch of dead links. I rather doubt this is the case, and another such search found a record with the same label, but that one is not a dead link.

Wait … a little more searching turns up an answer on Google’s How to Interpret your Search Results help page where it says that

‘Google augments results for difficult queries by searching a supplemental collection of more web pages. Results from this index are marked in green as “Supplemental.’

I am assuming that this is new, in part because doing a site search at Google for ‘supplemental’ results in zero hits, even though they have a help page with that answer.”

  1. I get the same thing with my site every now and again. Google only lists one page (home page)

    When I do this search: allinurl: http://www.ground-beef-recipes.com I sometimes get all my pages listed, but only the home page is not a Supplemental Result.

    This does not happen every time. I cannot find a true pattern to this, but it happens on average every 2nd day.

    Anyone knows how to remove my pages from this Supplemental Results database and into the real google database? Any help / suggestions welcome.

  3. i was wondering this, too. i was searching for my blog on google, by typing “xanga hoogli”. next to my xanga, it said supplemental result.

  4. Supplemental is Googles nice way of telling you that it doesn’t have either a recent copy or (most likely) a full indexed copy of the site. The results are supplemental because it cannot accurately give you the most relevent results – based upon what it has. If Google doesn’t have all of your pages… it is most likely because it has chosen NOT to spider them all, or has stopped the indexing… (normally due to duplicate content – sometimes due to slow server). So in a nut shell its NOT GOOD. Hope that helps.
