As is known, Google maintains an index parallel to the main index. This index contains all the supplementary pages as Google have been erased from a domain, returning a 404, or is no longer the links can be achieved through natural domain.
Only when the browser can not find more search results for a given, then Google shows these additional results. For this reason, if Google has moved the pages of a website to further its index, this site disappears almost entirely on the rankings.
In recent months, many projects have appeared only as additional results exist without a reason clear. For this reason, many webmasters were looking for ways to know what additional pages in a website.
A few days ago I read in a forum on a way to control the additional pages of a domain or using a small trick: site: my-dominio.com *** the result of this search shows the list of pages that are as Supplementary.
