Checking for Supplemental Listings

Checking for Supplemental Pages

Following on from yesterday’s article - What is the Google Supplemental Index - I’ll tell you how to check for supplemental pages on your website and why you don’t want these pages to remain as supplementals. Tomorrow, I’ll outline the various reasons why web pages feature in the supplemental Index, rather than the main Google index and tell you how to deal with the issue.

How to check for Supplemental Results

To check to see if any of your pages are in the supplemental index, simply use the Google site command in the Google search box: site:www.yourdomainname (, for example). This brings up a list of all of your pages that are listed in the Google index.

Go to the last page that is listed and click on repeat the search with the omitted results included, if it appears. If it doesn’t appear, all of your pages are already showing. In either case go back to the first result. Go through the results and make a note of any results that have the words Supplemental Result after the page size, for example:

Kenkai Report

Kenkai Report. Server Information. IP Address, Server Location, United States. Host Name, Server Type, Apache - 26k - Supplemental Result - Cached - Similar pages

The supplemental entry above came about as the chap from  who ordered a free report, that was for his eyes only, decided to link to it from various forums and because it was never intended to be indexed, so therefore not optimised in any way, it ended up in the supplemental index. It has now been redirected, but is likely to take weeks, if not months to be deleted from the supplemental pages.

The reason that you need to make a note of all of the pages is that there are numerous reasons why pages end up as supplementals and various ways of dealing with the problem and I’ll be explaining the different methods in the next few days on the Big Man’s SEO Blog.

Disadvantages of Google Supplemental listings

As I explained yesterday, once a page goes supplemental, it’s extremely unlikely ever to show up in the search results. The only time that it will show up is if there are absolutely no relevant pages in the main index for the requested search phrase and even then, it really has to be an obscure search term. If your hope is to sell a popular product like a Plasma screen TV from a supplemental page, you’d have as much chance as I have of outrunning the roadrunner with an anvil tied to my dangly bits (or even without the anvil!)

On top of that, supplemental pages lose all PageRank and can mess up a site’s internal linking structure, which can further mess up a site’s overall ranking in the search engine results.

So why does a web page go supplemental and what steps can you take to get your web pages out of the supplemental index? I’ll give you full details in the next exciting episode, which will appear in the next couple of days.
