Google supplemental result bugs

Posted on 2006-04-26 under News

We’ve been noticing some updates on the PR and supplemental results of Google. Not much to go by, but many sites seem to have been affected and dropped into the supplemental results, which means that they get crawled less and thus get less traffic due to the pages being dropped out of the main search index.

What are supplemental results?

Here’s what Google says:

"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."

Unfortunately it seems as if Google are experiencing a few bugs, which are still after effects from the Big Daddy update, allthough according to Google Guy they’re addressing the issue.

Our advice would be just to sit tight and not try to change your site code. Go about your normal routine of adding relevant content that your users have come to know you by.

With regards to PR, the update seemed to have gone by without much problems. According to Google being dropped into supplemental results will not affect your PR.

Reasons for being dropped into the supplemental results are sketchy. First off Google mentions that dynamic URL’s with many paramaters might be a target, though since there are known bugs, some people have also mentioned duplicate content penalties and the lack of inbound links. Orphaned pages (which you still have on your server, but to which no pages on your site link to anymore) also fall into this category. Have a look around your site to see how you can address these issues.
