So you started your blog with Blogger and now have decided to use WordPress. You also do not want to lose all your posts that you did because maybe your pages are ranked in Google for their key terms or because of their search engine optimized permalinks. You have to be sure to set your WordPress permalinks exactly the way beekeepers that blogger has them or else you can lose your indexed pages. For example, your posts will be the name of post followed by the month you posted ending with the day you posted. So be sure to set this up the same way in WordPress and then in your WordPress dashboard.
