Getting Out Of Google "Purgatory" -- The Supplemental Index
If your site is in Google Purgatory, prepare to spend some time suffering. Google maintains two separate databases of indexed web pages. The main index holds billions of pages, and this where most search results come from. The second is called the "Supplemental index," and searchers will never see those pages unless they put in long and specific keywords that are relevant only to some supplemental index page. Therefore, don't expect any pages in the Supplemental index to receive any significant traffic from Google. Go to Google and run the standard query to find out whether your site in indexed -- site:yourdomain.com . If you see the words "Supplemental Result" following the page size, that page is in the Supplemental results. Here are logical reasons for your pages to be included in the Supplemental results:
1. Your page is duplicate content.
2. Your site doesn't have any real, original content.
3. The page is orphaned - that is, there're no links to it.
4. Your site's content has been "scraped" -- that is, you've just copied search engine results pages or converted RSS feeds to static HTML pages.
5. You've used spammy techniques to promote your site.
6. Your page seems to exist only to generate Adsense revenue. Use the page to sell something.
7. Your page software generates URLs with a "SessionID."
8. Your site's pages are dynamically generated -- and timed out when Googlebot was visiting your site.
9. Your dynamically generated page URLs contain "&ID" or "?".
