Go to G and type in some of the urls of the OLD pages which have been 301 redirected to new pages (i.e. "www.example.com/abc.htm". Try at least 10-20 of them to get a good sampling. If they come up in the index with the NEW title and description and with the OLD URL then you are probably a victim of the phantom 301 redirect bug. It hurt us for almost a year. To confirm, type in the G search field: "site:www.example.com". If the results show totally random pages from your site on the first page, of results... you most likely have the duplication penalty. If you get a fairly good representation of your home page FIRST and other primary pages in the top 3 pages, then you are probably not a victim of this G bug.
