Web pages inserted in supplemental index would rarely show up for competitive keyword searches. If they show up at all, the results from Google’s main index would show up towards the top, followed by results from the supplemental index. If a website’s pages are placed in supplemental index, it is a good indication that Google may not be sending too much search traffic for those pages from its search result pages. A good way to check if one’s site pages are in the supplemental index is to run a search on Google and browse through all the result pages to spot any “Supplemental Result†tags. Contrary to what some SEO experts feel, when a site’s pages have been placed in the supplemental index, it does NOT indicate that the site has been penalized, even though the effect is somewhat the same. Google claims that it does not move a site's pages from their main index to their supplemental index in response to any violations of their Webmaster Guidelines. www.redalkemi.com
