Why Does Google Have A Supplemental Index?
Mike “Make Mine a Merlot” Grehan:
Q: Why does Google have a supplemental index?
A: Well it has to take a dump somewhere!
“Supplemental”. Might as well read “a page that is temporarily banned due to quality issues”

Pete,
I’ve seen good sites, with good pages go into the supps. If they meet a quality threshold they soon reappear. If they don’t, they’re effectively finished.

Ditto. Link quality, mostly.

What I have noticed is about supps is that. When a new page is created on a website, Google indexes it and wait a some time to check it gets any backlinks, else it puts them in supplemental. Its especially the case with newer sites.
