Suite au post de Jan http://forum.taggle.org/viewtopic.php?id=528 je fais un nouveau thread avec un titre plus explicite qui pourra servir à tous.
Lu sur WMW -http://www.webmasterworld.com/forum30/31654.htm

Voici la méthode pour remettre dans l'index un petit nombre (- de 20 URLs) d'URLs qui sont passées en résultats supplémentaires

1) Place a new, nearly blank page on old/supplemental URL.

2) Put no actual words on it (that it could ever rank for in the future). Only put "PageHasMoved" text plus link text like "MySiteMap" or "GoToNewPage" to appropriate pages on your site for a human should they stumble onto this page.

3) If you have twenty supplementals put links on all of them to all twenty of these new pages. In other words, interlink all the new pages so they all have quite a few links to them.

4) Create a new master "Removed" page which will serve as a permanent sitemap for your problem/supplemental URLs. Link to this page from your main page. (In a month or so you can get rid of the front page link, but continue to link to this Removed page from your site map or other pages, so Google will continually crawl it and be continually reminded that the Supplementals are gone.)

5) Also link from your main page (and others if you want) to some of the other Supplementals, so these new pages and the links on them get crawled daily (or as often as you get crawled).

6) If you are crawled daily, wait ten days.

7) After ten days the old Supplemental pages should show their new "PageHasMoved" caches. If you search for that text restricted to your domain, those pages will show in the results, BUT they will still ALSO continue to show for searches for the text on the ancient Supplemental caches.

8) Now put 301s on all the Supplemental URLs. Redirect them too either the page with the content that used to be on the Supplemental, or to some page you don't care about ranking, like an "About Us" page.

9) Link to some or all of the 301ed Supplementals from your main page, your Removed page and perhaps a few others. In other words, make very sure Google sees these new 301s every day.

10) Wait about ten more days, longer if you aren't crawled much. At that point the 15% datacenters should first show no cache for the 301ed pages, and then hours later the listings will be removed. The 85% datacenters will however simply revert to showing the old Supplemental caches and old Supplemental listings, as if nothing happened.

11) Acting on faith that the 15% datacenters will be what Google chooses in the long run, now use the URL removal tool to remove/hide the Supplementals from the 85% datacenters.

Ne vous emballez pas quand même car l'auteur ne garanti rien et pense que seulement 15% des sites peuvent sortir du caca avec sa méthode.
Je vais sans doute faire un article là dessus avec la traduc en français
