An interesting side effect, is that one of the pages that became Supplemental of course was no longer found in the SERPs at the #8 – 10 position it had been since it was first published but at the same time, the entrance page, which contained a brief abstract of the full article became listed instead.

But, if Google reports of the Supplemental index being fully done away with are true, http://googlewebmastercentral.blogspot.com/2007/07/supplemental-goes-mainstream.html by the end of this Summer, Supplemental should have gone the way of the Dodo. Unfortunately until that time, we are not only still living under the cloud of the Supplemental index but now, we can’t even see when we are under it, at least not without jumping through hoops to find which pages are Supplemental using other techniques. :-(

I wouldn’t delete pages if there supplemental unless it was a duplicated page.

Great information, and I am sort of agreeing with Adam. But, I would suggest to keep testing things out and let me know your results.

Thanks for your time,

Here is the lame part:

You can write the most useful, informational article on something BUT if it exists on a site with few incoming links (but several pages) it is a dead document. This is how stupid Google has become, I will no longer defend them in this area because I got sites that prove their obsession with incoming links/pagerank.

It has absolutely nothing to do with quality, if you have many pages you better have obtained many links, period.

Do a little test (I have!) take a document that is in supplementals and move it to a site with enough pagerank, it will outrank the best because it is in fact the best! Now move it to a website that has no links/pagerank, watch it get thrown in the trash. Ain’t it great? Not!!!

Seriously, this issue never bothered me much. I’ve seen supplemental content rank for a bunch of stuff that has brought me traffic and main index content bring me bugger all.
