If you change the title of a blog post (after it’s published) by only changing the title block, the link to it will be broken wherever anyone has linked to it. There is an easy way to avoid this in WordPress.
- Sign into the back-end of your blog and find the published post you want to change.
- Make desired change to the text in the title block. Copy all of this text.
- Look just under the title of your post. You’ll see “Permalink: http://yourblogdomain/title-of-your-post/”
- Click the Edit button to the right of your blog URL.
- Delete the ENTIRE blog title, and paste the new one. If you don’t delete all the text before pasting the new title, this will not work. (If you type the new text instead of copy/paste, do not type the hyphens that WordPress added between each word.
- Click OK.
WordPress will redirect the old link to the new one. That’s it.
Check Broken Links Within Your Blog
On another note, you can monitor your blog for broken links using the Broken Link Checker plugin. Once it’s activated, it’ll check your blog on a regular schedule that you set and email you with the results. You’ll be able to view, edit, unlink, or otherwise change the links.
