Changed the permalink structure and don't want to lose your SEO.
This plugin will redirect the old postname% permalink structure to the new one as long you keep the same slug in the posts.
It works by searching posts by the slug name that comes in the request, so as long as you keep the post slug intact, it should be able to find the post and redirect to whatever new permalink it now is..
Let's suppose you're using %postname% as your permalink structure, but after some time you find out it's not good structure and you change it to %category% %postname%, the old links will now generate 404 page, because there's nothing there anymore..
In this example your site is http my-cool-domain com and you have post with the slug 'my-cool-post under the category 'news With the old %postname% structure you would access this post with URL http my-cool-domain com my-cool-post.
With the new %category% %postname% structure URL will now be http my-cool-domain com news my-cool-post.
Notes * You should keep the old postname slugs, or the plugin will not be able to find the posts based old links request. * This plugin supports WPML...
