The #1 Worpress plugin to save your website from losing traffic and Pagerank after changing your permalink structure.It has been updated to 2.5 compatibility. Download version 1.3 here.

After Alexanders feedback, I fixed a bug in the WP plugin “Permalinks Moved Permanently”.

Before, the plugin would not work if your old permalink structure did not contain anything between the domain and the post slug. So this would not work:

http://www.example.com/post-name/

The latest release (version 1.2) does.

If you have been experiencing this problem too, download the new version here.

Thanks again, Alexander.

If you just migrated your WordPress blog from one permalink structure to another, and you don’t want to lose the traffic that accesses your blog through the old permalinks, this is for you.

Right before the old permalink generates a 404, this simple plugin grabs the slug from the end of the request and checks if there’s a post with this slug living somewhere else on your blog. If so, it will generate a “301 Moved Permanently” error, and forward your user to the new location of your post. It’s simple, but effective. — Read on
