Seo:Supplemental Page Issues
Monday, July 14th, 2008“Supplemental Hell” to webmasters, the issue has been lurking in places like Webmasterworld for over a year, but it was the major shake-up in late February (coinciding with the ongoing BigDaddy rollout) that finally led to all hell breaking loose in the webmaster community. You may be aware that Google has two indexes: the main index, which is the one you see when you search; and the Supplemental index, a graveyard where old, erroneous and obsolete pages are laid to rest (among others). Nobody’s disputing the need for a Supplemental index, it does indeed provide a worthy cause. But when you’re buried alive, it’s another story! Which is exactly what’s been happening: active, recent, and clean pages have been showing up in the Supplemental index. The true nature of the issue is unclear, nor has a common causing leading to it been determined.
