I am going to be transferring my WP blogs' content to another word blog platform, probably WP as well but with a different keyword rich subdomain.
What I am worried about is if the search engines penalize the new blog with duplicate content. If I close the previous WP blog right after transferring the XML file, would this be a concern?
Another reason is because of links which I've built which might be penalizing the blog ranking. These were mostly on high pr spammy blog commenting sites, which were mainly auto approve with other spammed links etc.
