Search Engine Supplemental Index
Do you know about Google's Supplemental Index? It is the place where web pages go to oblivion, otherwise known as Google Hell. Pages in the supplemental index will cause a drop in search engine traffic to your website - definitely not recommended. Here is a quick way to find out the position of your pages:
Go to Google.com and in the search box you type " site:www.yoursite.com *** -sjpked" replacing 'yoursite' with your real domain. The results will show you which of your pages are lurking in Google's Supplemental Index.
