It use to be that Google did a “Google Dance” once a month indexing everything and if you were lucky you held on to your position or climbed up some. The less fortunates saw their site head for the back forty or disappear entirely. One of the famous ones was the Florida Dance that happened before a recent Christmas, dropping a lot of commercial sites the never-never land and getting these online businesses upset going into the Christmas shopping season.
The Dances are gone now. Google uses a different strategy. There are billions of pages, and the indexing challenge for returning the good sites to a searcher was too big for “the old way”.
Google now tries to return only pages with good ranking that are relevant to the search. These are indexed every month or less – some indexed every day. The main page of this site was indexed less than a week ago. The more important your page, the more often Google will index it. Sites considered less relevant are banished to the supplemental index. These are only returned to the searcher if Google can’t find much matching the site. These pages are indexed much, much less frequently if at all. If one of these pages is returned in a search, it is marked supplemental. Here is an example from our business site:

Don’t worry if some of your pages get into the supplemental index. We have thousands of pages in our site and a good number in the supplemental index. We just make sure the important pages aren’t there. Our book shows you how to get your pages out of the supplemental index.
To see if you have pages there, search your site on:
site:www.netadventures.biz *** -yuiopjkl
where the domain specified is your own. Use the three asterisks and any nonsense string with a minus sign in front of it. Avoid any special characters in the string. This is an undocumented feature, so don’t trust it too much.
PS – yes, we know there are some bad links in this site. We are working on that.
