I've posted a post on WordPress and it's been indexed by google under this url: http://digital-horizon.net/socket-programming-tutorial/
Considering that I'm using WordPress SEO plugin by Youst and it keeps updating my sitemap:
If I edit the post and change the permalink, would that hurt the SEO? Will google automatically understand the change (either from the sitemap being changed by the plugin or crawler being smart enough) and remove the URL or would it just throw me a 404 error? If it does throw a 404 error, should I care or not?
I appreciate your replies beforehand.
