I'm moving my blog from Wordpress onto a customized domain / blog community. Is there any way to avoid being hit with duplicate content penalties for Google rank if my old blog posts exist on the old (Wordpress) and new (specialized blog community) platforms?
Unless you can 301 redirect your old blog to yuor new one, Google may well see it as duplicate content... I've had this trouble myself... still havent got the ranking up for the new site, even thought the old URL is no longer valid....
