WordPress Comment Spam As you keep on posting unique and quality content your blog becomes more popular on the web. With the growing popularity chances of encountering spam also increases. You can receive spam in 2 ways. One is Comment spam and the other is Trackback spam. A Trackback is nothing but a link to one of your blog posts in their blog post. Normal comment looks like in below pic with comment author’s name, email id, optional website address and ip address.

Trackbacks are fine as far as the link is from a legit blog. Sometimes you also see Trackbacks when you inter-connect your blog posts. Why should we deal with comment spam and trackback spam? As we told in our previous posts if you are linked to spam, search engines will also treat you as spam and legit users also stop commenting if they see lot of spam on your blog. In this post we will discuss some WordPress plugins which controls WordPress comment spam and trackback spam.

WordPress Comment Spam – How to Combat?

Akismet – Akismet is a famous WordPress plugin which automatically catches spam comments and trackbacks. Just install the plugin, visit Akismet website, get your free api key and enter that in your Akismet plugin settings. That’s all, plugin moves all suspicious comments to spam or deletes them.

Captcha – Spammers use Auto Spam Bots to auto comment on the blogs. Akismet catches suspicious comments and moves to Spam. We want to reduce spam comments count. Using Captcha is one the best ways to reduce auto spam comments. SI Captcha Anti-Spam and Captcha are the best plugins which provides the feature of entering the Captcha before publishing the comment. But we don’t recommend using captcha because users feel more frustrating to fill captcha for commenting.

GASP – Growmap Anti Spambot Plugin adds a client side generated checkbox to your comment form asking users to confirm that they are not a spammer. It is more convenient than entering a Captcha.

Simple Trackback Validation – This plugin validates all the incoming Trackbacks. First it checks the ip address of the trackback sender is equal to ip address of the webserver the trackback url is referring to. Next it retrieves the webpage located at the URL included in the trackback. If the page doesn’t have a link to your blog, the trackback is considered to be spam.

In our case earlier we used to receive approximately 400 spam comments daily but after installing all these plugins our spam count got reduced to 10. If you are a WordPress blogger we strongly recommend using Akismet, GASP and Simple Trackback validation plugins to control comment spam and trackback spam on your WordPress blog.


If you are connected to spam, search engines will penalize your website severely. Also if visitor sees lot of spam on your blog he/she won’t visit your blog again. Thus the bounce rate will go down. So one must handle the spam issue very seriously. If you liked this post please do us a favor by tweeting this post on your profile 🙂
