This plugin adds an “External Link” section to the post editor.
If you’re publishing posts that are primarily used to link to external news articles or resources, the plugin overrides the post’s permalink and redirects users to the specified external URL when they click the post.
The “External Link” section has two options:
<ol>
<li>External link (This URL will replace the return value of <code>the_permalink</code>)</li>
<li>Open in new window (checkbox)</li>
</ol>
By setting an external link, the link in your widget, post archive and so on, will refer to the new URL you saved.
<h4>Settings</h4>
This plugin adds a new section to Writing Settings with 3 different options.
<ol>
<li>Post Types </li>
</ol>
Lets you select which post types should support external links.
<ol>
<li>Attributes </li>
</ol>
When set to Automatic, the target and rel attributes will be automatically added to anchor elements linking to the new URL, using jQuery.
When set to Manual, developers must manually add anchor elements. You can either use <code>tsep_anchor_attributes()</code> to generate the href, rel and target attributes, or use <code>the_permalink()</code> to populate the href attribute and <code>tsep_target_attributes()</code> to add the target and rel attributes separately.
Easy method:
<pre><a class="some-class">Click here!</a></pre>
With separate attributes:
<pre><a href="" class="some-class">Click here!</a></pre>
<ol>
<li>Single Page Content </li>
</ol>
This option allows you to manually write an anchor element that will be added to the post’s content. Use %link% for the external link, and %rel% for the target and rel attributes.
<pre><a href="%link%" rel="nofollow ugc">Click here!</a></pre>
This will produce the following output:
<pre><a href="https://example.com" rel="noopener noreferrer nofollow ugc">Click here!</a></pre>

Taro External Permalink

A WordPress plugin that allows selected post types to redirect to external URLs.

When you change the permalink structure then this is a problem for bookmarks of users and also for search engines to link to your posts. This plugin uses the slug of the new url and search for a ID in the database of WordPress. If it finds a post according to the slug, the Plugin will redirect to the correct post and send a header message “moved permanently 301” to change the url on the index of search engines.

Change Permalink Helper

Awesome!

It checks the Permalink and redirects to the new URL, if it doesn't exist. It sends the header message "moved permanently 301"
