Supplemental Index. How Exactly Do Webpages End Up in It and How to Save Them By: Cristian Lungu

Frankly I don't know if this is breaking SEO news for you or not but Google, besides it's main index has another one, called Supplemental Index. This inventory is occupied by web pages and in some cases entire websites that were reported by Google bot as having some rare SEO illnesses. These sensitive issues will be discussed further in the article.

Although the webpage isn't in the main index it continues to be indexed, as a matter of fact with even FEWER restrictions as opposed to the main index.

And this supplemental index carries one gloomy predicament - that page or even entire (slim) websites face Google abortion. In other words Google stops showing that webpage no matter the position.

One important distinction must be made here and this is: Don't confound the SI with Google's most feared Sandbox Effect. The Sandbox effect tends to appear with webmasters who conduct aggressive SEO practices such as intensive link building campaigns, usage as anchor texts of expensive keywords (as judged by Adwords stats), getting involved in doggy link farms and link exchanges in general, etc.

Before I present the major reasons why a webpage slips in the supplemental index, please take note that this is a auto generated algorithm and no human inspector supervises who gets or should get in and vice versa.

What causes a webpage to fall into Google's Supplemental Index:

1. inconsistent internal linking - the most common way a webpage ends up in the SI;

Here's a short know-how for how Google operates: On a regular basis, Google performs a thorough indexation for the sites it has in it's index. But apart from this regular inspections Google also compares the newly extracted info with it's past recordings for each particular site.

If, after comparing it's previous recordings with the current site inspection report, Google finds out that some of your older webpages don't show up in the newly extracted data package, then it assumes that you've dropped them. Naturally these "out-of-date" pieces of content are qualified for the supplemental index.

What course of action to take in this situation? Quite simple. Initiate a link building campaign and let Google know that your webpages are still of interest for it's users. Web 2.0 platforms are a good starting point for your link building campaign.

2. the homepage or category page doesn't contain a direct link to the penalized webpages;

What you should do: Easy, Get a link on the home page or category page. Check out the feedback, namely if the penalized webpage shows up in Google index after a week or so.

3. webpages are not updated after being indexed for more then 1 year - this generally happens with young domain names and few webpages in their sitemap;

The solution, again is predictable: See if the content is still up to date; if it's not, write it all over again. Special attention should be given to the headings and title tag that must be rewritten thoroughly.

Other shortcuts to reclaim your de-indexed webpages:

> Set in motion a submission schedule to prominent submission directories like Yahoo Dir and DMOZ;

> Submit press releases on a regular basis. At least once at every six months work with services like eReleases and PRWeb;

> Launch a backlink campaign that focuses entirely on quality. Obtain a minimum of 25 backlinks to your home page;

> Optimize your on-page factors.

Having a webpage in the supplemental index doesn't serve you at all. No matter how insignificant the webpage is. So be sure to save it before your site's overall authority drops.
