Google's Supplemental Index - Reduce Labels or Sink!

When you add your blog to Google it sends it's spiders to index your blog. The spiders index all the pages in your blog and arrange them into a Main Index and a Supplemental Index. You should take all steps possible to prevent your pages from landing into the Supplemental Index.............

When people search using Google it returns the results found in the Main Index. If it does not find any results there it turns to the Supplemental Index. When Google spiders crawl your blog whatever duplicate content they find is dumped into the Supplemental Index.



When you apply labels to your posts in the bottom frame of the post editor when creating a post or on the posts list page you are actually creating duplicate content. For example the following links on a New Blogger blog will bring up the same content :

http://YOURBLOGNAME.blogspot.com/YEAR/MO...ST_TITLE_A

http://YOURBLOGNAME.blogspot.com//search/label/LabelA

http://YOURBLOGNAME.blogspot.com//search/label/LabelB

when the Labels A and B are applied to the post : POST_TITLE_A. When Google crawls your blog the duplicate content pages are placed in the Supplemental Index. The more labels a post has the more content is duplicated in the blog.
