WordPress is a great platform for interactivity with readers who want to leave comments. The publishing platform comes with a powerful commenting system that works well except for one caveat. Comments come with links already enabled, and this can be a bad thing for your site if the comment link is not related to your business or worse: spammy.
To delete links in comments, you can mess with the PHP in the functions.php file, but this can be risky and often times will take down your site if not done properly (note that this can be fixed by going into FTP and removing the bad code).
If you don’t feel like going this route, a simple and easy solution is to use a plugin called Remove Links from Comments. You can find this by searching for “remove links from comments” in the add new plugin area of your WordPress site. The plugin removes the ability for the person commenting to add links as well as takes off any links that are currently on the site.
It is a rather efficient and light plugin, so although I don’t recommend using plugins when there are other options, this one does do a rather fine job.
