Types of Supplemental Results

These are some of the types of supplemental results you may encounter when running a site:domain.com search:

> Previously indexed pages are dropped, leaving only supplemental copy behind. In this case, your page didn't "go supplemental" due to any obvious duplicate content reasons. Instead, your problem could be due to lack of PageRank or a bad outbound link to a crap site that reduces your page's trust score. A few high quality inbound link may set things straight.

> A Page triggers a duplicate content filter and is flagged as supplemental. These pages will not return to the main index or dropped completely until Supplementalbot recrawls your pages. The key here is not to have Google mistake good pages for duplicates.

> Pages that are correctly indexed show up as supplemental depending on the search. Google keeps several copies of the same page, older copy usually stored in the supplemental index. When a page content changes, some queries can return pages listed in the main index as a supplemental result.

> Recently crawled supplemental pages with fresh cache yet to be evaluated. The two processes (refreshing the supplemental index, and evaluating them for re-inclusion into the main index) happen separately. Therefore, if you see some pages with recent cache dates listed as supplemental, it doesn't necessarily mean it will stay supplemental for long.
