Supplement Pages

[AuroIN-SEO]

Supplemental pages are those pages that Google consider not important enough to include in their main index. Supplementals usually occur when there is duplicate content or no content in a page, if there is no inbound link to that page , and if there is duplicate title or Meta tags. A page can be optimized to so that it does not come under supplementary result of SERP

another one reason, When a site is new and made some changes to their some meta tags specially to title page then there is high chances that it could be resulting to supplemental result.

[coolguy27]

sites in supplemental pages are pages with duplicate, no links etc...

it is bad 'coz if you are in supplemental index you can rank in SE but you can't rank high....

Pages in supplemental are pages with no link juice.

Thank you Ar3d for this information.

Google has stated over and over again that the number one reason for a page being in the supplemental index is low pagerank.

... the main determinant of whether a url is in our main web index or in the supplemental index is PageRank. http://www.mattcutts.com/blog/infras...-january-2007/

Because Pagerank depends on links

Yes, I am aware of that. I was responding to the person that started this thread because so many people try to automatically blame duplicate content.

Do you have any tips on how to keep website with 1000s and more pages out of supplemental index. I mean how to manage PR for 1000s of 2nd and 3d level deep pages.

supplemental comes from duplicate pages

[Johan007]

More precisely it come from similar text on pages. As mentioned low PR pages but also pages with poor semantic markup such as no <title>.

There are some reasons why there is a supplemental results and this are:
1.not enough quality inbound links to your site
2.Cannonical issues are causing PageRank to split.
3. Duplicate contents

The website is supplemental when index display URLs of web pages identified as relevant for the search query, but judged less important than others.The supplemental index is being crawled and updated regularly, although not quite as often as the normal index. However in case a web page in either index is found more suited for the other, it will be updated as so. If you want to know more about click this--> Supplemental pages

Cricket is right LOW PAGE RANK is the main cause of Supplemental REsult..
The results you have on your site depends on the quantity and quality of the links you have..
Duplicate content is the side effect of the Supplementary Result..

Other causes of supplemental results are:
Lack of Trust
Manipulative linking practices can also lower PageRank flow into a domain, thus creating more supplemental pages.Manipulative links include excessive reciprocal linking, link injections, and paid links.

High Page Count
A large site with a high page count is also generally more vulnerable to the supplemental index than a small site because inbound PageRanks divided among several hundred thousand pages tend to be lower than that divided up among only a few dozen pages.

that is base on my readings!!!

[netsearch]

link networks can put you in the supplemental pentilty box

[grace029]

It can also be caused by having the same HTML title and similar meta description on each page. It can often be made worse by excessively large website navigation systems duplicated on all web pages.

changing URL's can caused SE indexing problems when done improperly and it will lead to Supplemental result...

[Natural Elements]

Supplemental results should not exist, period !

Not..... I have changed my meta data and even tweaked the title and have never had a page get put in the supplemental. Google doesn't really put much importance on the meta tags anyway.

To avoid having your pages fall into the supplemental index be sure to:

- Provide a significant amount of unique content on each page (ie. more content than navigation)
- Avoid spammy linking practices, careful who you link to in other words.
- Try using unique titles on every page if it's possible.

This won't guarantee that you won't have any supplemental results, but it will lower your risk.

BTW: If your entire site is supplemental then you've got some work to do! In *my* experience, outgoing links were to blame.

Google is starting to crawl the supplemental index more often, and soon the distinction between the main index and the supplemental index will be blurring.
