Welcome to the Q&A Forum

There  is no difference between "Redirect 301", "Redirect permanent" and  "RedirectPermanent". It is clear from mod Alias documentation: "This directive makes the client know that the Redirect is permanent (status 301). Exactly equivalent to Redirect permanent."   "permanent - Returns a permanent redirect status (301) indicating that the resource has moved permanently." But, these directives are really confusing, because they are not page to page, but directory to directory.  For example: Redirect 301 /a-very-old-post/ http://yoursite.com/a-very-new-post/ Surprisingly, it will redirect all old subpages to new subpages. In particular it will redirect  /a-very-old-post/page1 to /a-very-new-post/page1  Therefore better to use RedirectMatch or RewriteCond+RewriteRule for page by page redirections and for redirections with query strings.

Good news is that after I did the same tedious process myself, my SEO results went up!
