How to tackle Google’s Supplemental Pages?
Supplemental Results cause a downfall in referrals from Google; For example, this command lets you find out the pages in Supplemental Index; www.google.com/search?&q=site:www.organicseo.in+***+-jjjj
While lurking through a few SEO Forums, I came across a few good solutions that can prevent pages from getting Supplemental in Google.
What’s a “supplemental result?” http://www.google.com/support/webmasters/bin/answer.py?answer=34473
A supplemental result is just like a regular web result, except that it’s pulled from our supplemental index. We’re able to place fewer restraints on sites that we crawl for this supplemental index than we do on sites that are crawled for our main index. For example, the number of parameters in a URL might exclude a site from being crawled for inclusion in our main index; however, it could still be crawled and added to our supplemental index.
If 30% of a site’s pages become Supplemental; then the site loses 30% traffic from Google. Thus, it is better to avoid from getting into supplemental results through the following.
1. Unique contents on-page can prevent pages from getting into Supplemental Index.
2. Unique title and meta tags can help in avoiding supplemental results.
3. Over optimization and Excessive internal linking should be avoided.
4. A link from the home page can being a page back into Google’s prime index.
5. Removing unnecessary commented tags within page’s source code can prevent Supplemental Index.
