How to Change Old Permalinks to New Permalinks without loosing your Google Indexing
I used to have following custom permalinks previous post for slug url for my blog post title.
Now I changed the custom permalink structure as below which is seo friendly permalinks setting for your wordpress blog. By doing so Google will love it to show your Blog.
By doing when you try to browse old blog post indexed by google it will show result found nothing. So to preserver your previous google index you need to migrate the old permalinks to new permalinks.
I have older post url as : http://www.satanictech.com/2010/07/how-to-phpmyadmin-with-virtualminwebmin/
This is now replaced by new url as : http://www.satanictech.com/how-to-phpmyadmin-with-virtualminwebmin/
In order to redirect it you need to have plugin called permalink migration.
By installing this plugin your older post will not loose your lovely visitor.
