How to Spot Comment Spam

If you have a popular website, you will start to notice that you will get spam every once in an awhile. The most common form of spam are comments from a website because they are the easiest form of information submission. To rank higher in Google, a long time ago, linking to many websites was a major ranking factor. Now Google does not consider this a major ranking factor, but there are still bots out there that try to link to websites using the software. So how do you know if a comment is spam? Below we show you how.

People posting with no names

People posting with “viagra”, “earn more money” or other words that surely does not sound like a name is obviously spam. A person who is weary about giving their information out will probably just leave their first name, instead of random words.

Same IP address

If you see multiple comments from the same IP address, it is most likely spam. What is happening is that one computer is sending out all those spam comments to different websites trying to link to them. This form of SEO is called blackhat SEO.

Nonsense email addresses

There are emails that have plenty of words jumbled up. is an example. In the case you see below, we consider this as comment spam.

If you see words that are uncommonly misspelled, then that would be a sure clue that it is spam. Considering the amount of misspelled words should be taken into account also.

Nonsense comments

All of the remedies to spot comment spam we are about to mention is free. The first two are not SEO-friendly, although they do help in getting rid of comment spam once and for all.

With 4.8 stars as of writing this article, Akismet is a freemium plugin that takes care of comment spam. There is an option to automatically delete or blacklist spam. This plugin is perfect for those who do not want to see or deal with the types of comments as some of them are disturbing to read.


Install a social media commenting system plugin

This can be in the form of Facebook or Google plus commenting system. Only people with a Google or Facebook account will be able to comment.

The only downside to this is that it does not help with SEO.

Here is an all-in-one plugin that lets your users decide what social media profile they’d like to comment with.

Here are three Facebook commenting plugins: Facebook Comments WordPress, Facebook Comments by Vivacity, and Lazy Facebook Comments.

Install Disqus

Disqus does not help with SEO either. Disqus is a software that is embedded in the comments section using a plugin. Because this is embeddable, any comments being submitted will only be sent to Disqus. Human eyes can see the comment, but Google’s robots don’t. Google’s robots will only see embeddable text. Another downfall of this system is the need to register before submitting a comment. The registration process requires the user to check his or her email address which may take a few minutes. Unless the user submitting a comment already has a Disqus account, it would annoy and demotivate other users from commenting.

If it thinks that you are a bot, it might ask you multiple times. Google ReCaptcha also has a plugin available in the plugin depository.

    I have askimet, which catches a lot of my spam. They are pretty easy to spot, though, so if some make it through the cracks I can delete and block immediately.

    Spam can be a total headache and it’s important to spot those comments because sometimes the comments contain malicious links that could lead to a virus. I think this is a great guide for that as well.

    I have Askimet as well, and it catches tons of spam comments going into the blog. I didn’t realize how much spam hits blogs until I started doing this about a year ago. These are all great points to look out for!
