Convert all external links into internal or nofollow links!
This plugin is a fork of the hijacked and vulnarable “WP No External Links” plugin.
The following critical issues have been fixed: 
– Removed Cross-Site Scripting vulnerability. 
– Removed backdoor injected into original plugin. 
– Fixed creation of the new <code>links_stats</code> table: added charset collation and table existence check. 
– Fixed “Specified key was too long; max key length is 767 bytes” error on creating <code>mask_links</code> table. 
– Added removing tables on uninstallation.
No External Links plugin is designed for specialists who care about the number of outgoing links that can be found by search engines. Now you can make all external links internal! Plugin does not change anything in website database – it just processes the output. Now you don’t need to worry about your page rank dropping because of spam bots. You write any kind of http link and it becomes internal, hidden or nofollow! Of course, all the links will still be usable.
To make the long story short, your links like “http://gmail.com” will be masked into 
“http://YourBlog.com/goto/http://gmail.com” – or 
“http://YourBlog.com?goto=http://gmail.com”

Radar LinkHawk is a WordPress plugin that indexes outbound links across published posts and pages.
The plugin scans your content, stores each external link usage as its own record, and shows where every URL appears. This helps you review broken destinations, redirects, and link attributes without opening posts one by one.
With Radar LinkHawk you can:
<ul>
<li>scan all published posts and pages for outbound links;</li>
<li>review every usage row with URL, post, anchor text, HTTP status, redirect state, and nofollow data;</li>
<li>group repeated destinations in the URL Summary tab to see total usages and post counts;</li>
<li>filter broken, redirected, and nofollow links;</li>
<li>preview and apply bulk actions only to the exact rows you selected;</li>
<li>add nofollow, remove nofollow, replace URLs, or remove broken links while keeping anchor text as plain text;</li>
<li>export the current URL Summary or Usage view as CSV;</li>
<li>compare internal versus external link distribution in the Link Balance tab;</li>
<li>run weekly background status checks for saved external URLs.</li>
</ul>
Radar LinkHawk keeps editing tools and HTTP checks focused on external links. Internal links are tracked for analysis only, so you can compare content structure without turning the plugin into a full internal-link editor.
Radar LinkHawk does not require a cloud account. When you run a manual scan or enable weekly checks, the plugin sends standard WordPress HTTP requests directly to URLs that already exist in your content so it can store response codes and redirect outcomes.
