Why Do I Get So Many Spam Comments on My Blog?

It goes without saying – we’ve all experienced spam in one way or another. Whether it’s the mailbox packed with credit card offers, telemarketers interrupting the workday, or useless email sales pitches, spam shows up everywhere – and now spam is showing up in the comments on your blog.

While there are plenty of ways to minimize blog comment spam, many of the clients we work with don’t understand how or why blog spam happens in the first place. So let’s take a closer look at spam comments, how they hurt your website, and how to prevent spam from making it onto your blog.

For the Love of BackLinks

These poorly written and often nonsensical comments have no other purpose than to generate backlinks to another site. You see, Google assigns more authority and better search results to websites that have a large number of inbound links … also known as backlinks (links from one website – like your blog – pointing to another website – owned by the spammy commenter).

This led to the “selling” of backlinks by so-called SEO companies (“get cheap links” … sound familiar?) who spam blogs to generate a large quantity of links for their customers.  Then they say “Hey client, look at all the links we generated to your site.”

Here’s how it works … when someone leaves a comment on your blog, there’s a clickable link that leads back to their website. That link often underlies the “Author” name and, in some cases, shows up in the body of comment itself.

Bottom line: Blog spammers are trying to “game” search engine results by leaving links on every blog they find on the internet. Don’t let your blog be the next victim.

Spam Comments are the Sincerest Form of Flattery

It’s easy to be flattered by blog comment spam, especially if you’re new to blogging or haven’t seen any comment activity in a while. Spam comments use flattery, appeal to your good nature, and simply lie in order to convince you to give them the benefit of the doubt. Do any of these sound familiar?

“What a great post. I stumbled on your blog, have bookmarked your site, and will be coming back often.”

“You’ve offered fantastic insight on this subject. Probably the best on the internet.”

While these may sound legitimate and can easily have been submitted by someone who was being sincere, 99.9% of the time they are not.  Here are a few tips to help you determine whether to hit “approve” or “delete”:

  1. The comment is vague and doesn’t reference anything specific to indicate they’ve even read the post (because they probably haven’t)
  2. The comment is complimentary to the point that it’s over the top
  3. This is the clincher … the person doesn’t leave his/her real name. Instead, the “Author” that’s listed is typically a keyword phrase like “SEO Services Toronto”, “Cloud Software”, or “Gucci Tote Bags”

But don’t be tempted! Having spam in your blog’s comment field does more harm than good; these low-quality links on your blog lower the credibility and potentially decrease the value of YOUR website. Any suspicious, poorly written, or keyword-stuffed comments should be promptly marked as “spam” and deleted. Don’t let spammers take advantage of your blog and the content that you worked so hard to create.

Stop Spammers in their Tracks

If you’re using WordPress, there are some great tools available to quarantine and prevent spam comments from infecting your blog. To completely stop spam comments, you can turn off the comment field altogether.  But this also prevents your legitimate readers from engaging with your content which is one of the most important elements of having a blog in the first place.

Alternatively, the best way to handle spam is to install a WordPress plugin such as Askimet. This free “spam killer” tool analyzes the content of each comment against a huge database of information to determine whether the comment is genuine or not.  Based on our experience at Juice Marketing, the tool is very accurate.  So when a collection of comments have been quarantined (by Akisment) in your Spam folder, it’s relatively safe to just hit delete without wasting time reading through and analyzing each and every comment.

    Thank you for your article.
    I have already installed askmet plugin.
    Initially I never used to receive spam comments. But when I moved my subfolder to root domain I started receiving comments as spam.
    What can I do to receive comments that are not spam.

    Hi Mark,
    This info was helpful, thanks. But why do spammers leave so many comments on my blog without links? The link thing, I get. But a fair number of them comment as anonymous and leave no link to their site. The only link is the story on my blog they’re commenting on. When I click it, it does indeed link to the story. Just curious how this helps a spammer.

    I did a site redesign last Spring and Akismet was part of that. It has worked great. The question I have is that three months ago the number of spams the corralled exploded by 10X and is now running around 7000 each month. Is this normal? Is it affecting me in any way? Is there something else I should do?

      Conrad – we use Akismet and haven’t noticed any recent changes in behavior or increase in spam getting through. Perhaps your Akismet plugin was disabled/de-activated or maybe a license key is required? In any case, it shouldn’t affect you unless you’re allowing the spammy comments to go live on your blog/website. If you have them going live automatically without review/approval first, you might have a problem.

    I have a huge problem with spam on my blogs. I’m running askimat & using captcha but it hasn’t slowed them down. I’ve had to resort to using an ip ban plugin but they just keep on coming. These spammers are so stupid they’re posting the comments on my contact forms. If they were posting their comments correctly I would just shut off the comments but that’s not the case. On one of my blogs, the ip ban plugin has denied over 22,000 hits in the last 2-3 months but I still get at least 40 per week. Does anyone have any other suggestions?

    Karen – I’m glad you could vent and hopefully you feel a little better! Unfortunately, it’s hard to answer your question without really digging into your site and evaluating the specific entry your referring to (if there even IS an answer in the end).

    I noticed you’re using Blogger – I’m guessing that if you did a search on Google, you can probably find a tool for Blogger that would help combat the comment spam you’re getting. In addition from a technical standpoint if you’re able to identify the IP address of the “offender in Austria”, you might be able to block them from visiting your site.

    I hope that helps and good luck!

    Thanks for recommending a plugin. I find we get about 20 spam comments a day despite having a captcha set up. I will definitely be checking this out.

    I’ve found the Askimet tool to be useful as well (I have a couple personal WordPress sites), and non-intrusive, which is a big deal. We use Adobe Business Catalyst for our website and blog, and they do have a comment moderating system, but I got so sick of getting five to ten emails per day about comments from payday loans and golf equipment that I finally just turned commenting off completely. It stopped me from pulling my hair out, and since nobody had ever left a legitimate comment on the blog, we didn’t really lose anything.

    • says

      Keith – yeah, turning the comments off all together is an option (as mentioned in the post). While you lose the 2-way interaction that the blog is supposed to provide, it sounds like you get to keep from losing all your hair. A fair exchange I suppose!

    I think people really need to utilize the resources you gave. I have used a couple of backlink services and my ranking drop big time. I certainly will be using them.
