<p>For unmodified links Nofollow Case by Case works like a (do)follow plugin for WordPress. It simply removes rel=”nofollow” from your comment links.</p>
<p>Whenever you get the feeling that one of your comment links might be able to harm your own website reputation, if you think about SEO and found a link that looks a bit like spam but should not be deleted, you can replace nofollow to every single comment link at any time. If you want to replace nofollow for a link like that you simply add /dontfollow at the end of the link. You can do this for author links in comments as well as for the links you find in the text.</p>
<h4>This is what the plugin will do automatically:</h4>
<p><strong>1. Clean up some code:</strong><br />
It tries to remove all variants of rel=”nofollow”, target=”blank” and rel=”external” from comment author links and other links in comments first. A link will become a “real link” no matter if it is a pingback, a trackback or a “real comment”.</p>
<p><strong>2. Fix semantical incorrectness:</strong><br />
The plugin now applies rel=”external” – but ONLY for external links!</p>
<p><strong>3. jQuery functions of Nofollow Case by Case:</strong></p>
<p>a) The plugin detects rel=”external” in comments and opens those links in a new window.<br />
No need for target=”_blank” which would not validate in XMTML. jQuery replacement does.</p>
<p>b) The plugin tries to correct author urls that could not be fully replaced before.<br />
This has something to do with template development. Find more information on this within the FAQ.</p>
<h4>Add on</h4>
<p>You can try this <a href="https://wordpress.org/extend/plugins/nfcbc-seo-plugin-add-on/" title="NFCBC SEO Plugin Add-on" rel="ugc">NFCBC SEO Plugin ADD-on</a> for easier comment management. The plugin is an old one using javascript but still works. I currently do not have the time to rebuild it. A new version should later support Ajax and nonces and on the other hand will not support old versions of WordPress anymore.</p>
<h4>Alternative Tool</h4>
<p><a href="https://wordpress.org/extend/plugins/nfcbc-seo-light/" title="NFCBC SEO Light" rel="ugc">NFCBC SEO Light</a> could be used alternatively. It suggests “follow” or “nofollow” or “no link” automatically, depending on comments length. This plugin might be updated soon. I personally prefer Nofollow Case by Case.</p>
