Google’s Supplementary Index…
Some pages from a new site I’m building are in the Google index… or are they?
They show up as “Supplementary Results”. Which means they’re in the “supplementary” index… the “other” index… the pages that Google shows when it has nothing else to show. 
As they say,
“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.” source
So what can we deduce from the fact some pages have ended up in the supplementary index?
Well, this is by no means fact, but I would guess that to be in the supplementary index, a page would have to match these criteria…
1: The pages are fairly new (days, weeks or a few months old, not years)
2: The pages have very little Pagerank (few inbound links)
3: The pages probably have content on them that’s found on other pages.
I wouldn’t expect this blog post to appear in the supplementary index because, even though it’s new, it will appear at the top of the PR5 blog homepage and it’s 100% original content.
So how do you get your pages out of the supplemental index?
I would try increasing the Pagerank of the page itself so that your page is the one seen as most important for the content on that page and, if possible, add some original content to distinguish your page from others.
What do you think?
