After changing my robots.txt to disallow the Google Bot to spider some duplicate pages, I finally see the first results. A while back I wrote about how to get your site out of Google’s supplemental result index and since than I made only some small changes to my robots.txt file. After one month, my supplemental pages went down from 1.200 to 1.030. This does not seem to be a lot, but one month ago Linkrain was counting 150 pages less than now (new links added in the directory, new categories, new articles). So that’s a total of 320 pages less in the supplemental index. Also Google’s webmaster tools start to show first results about pages that were not allowed to be spidered by Google.

Once Google will spider all my pages again, supplemental results should decrease even more. In fact I’ve seen that many pages that I recently disallowed to be spidered, are still in Google’s cache.
In the article written one month ago, I listed some webmasters that had a great search engine traffic increment by tweaking the robots.txt. Actually I’m experiencing an increment too. Search engine traffic increased by 70%, and this only by getting a few hundred pages removed. There are many big websites with thousands of pages and thousand of supplemental results. These websites could achieve some incredible results by getting rid of some supplemental pages. I will now monitor my search engine traffic every day along with the number of pages listed in the supplemental result index to collect some more information about this topic


Just a question.. What is the problem of this supplemental pages indexed by google.. Why do we have to restrict them.?
To get more search engine traffic. By getting 300 pages out of the supplemental result index my search engine traffic increased by 70%…I think this is a good reason to start optimising your robots.txt
thank you I will try that robot.txt tips
Supplement pages are not valued by Google and will not be displayed in their main SEPRs indexes. Robot.txt can help to tell spiders not to index certain areas of your website to prevent them from being indexed. Read more about search engine marketing here
I think you’ve made a big point. It is really awful when people tell you such things like that. Awful it is!
