How to Protect Against WordPress Comment Spam

WordPress Tutorial #7

It’s so exciting to get your first comments on your new blog!

Until you realize they’re pushing some shady link, or selling something that has nothing to do with what your blog is about.

Then they become a big nuisance, also known as the dreaded comment spam.

What can you do?

When it comes to WordPress spam protection, the Akismet plugin is your first line of defense. Follow these easy step-by-step instructions.

There are two types of bad guys you need to protect your WordPress site from: spammers and hackers. Proper WordPress security includes both.

Spammers are at best a nuisance. At worst they can open the way for serious site problems.

Fortunately it’s not too difficult to thwart them.

Your First Line of Defense: Akismet

Akismet is made by a WordPress cofounder.. It’s designed to catch spam comments and hold them for you.

To put it to work, you just need the Akismet plugin and an API Key. I’ll show you how to get that.

#1. Install the plugin

In your WordPress Dashboard, click the Plugins tab on the left. After you do that, you’ll see a list of all the plugins that are already installed. If you don’t see Akismet there, you’ll need to add it. If it’s already installed, skip to step #

Click Add New.

Click the big blue Set up your Akismet account button.

Follow the prompts until you see this screen.

Select your plan

There’s a Personal option, which provides only basic spam protection. It’s for non-commercial use only. If you select this option, it asks for $36/year, but you can manually change it to anything from $0 to $120 annually.

The Plus plan is more robust, with advanced statistics, priority support, and permission to use it on commercial sites. It’s $5/month per site. Then there’s an Enterprise plan, which costs $50/month for unlimited sites.

The Plus plan is probably the one you want. Fill out the payment information, and click Continue. Note if you choose to pay annually, you get a whopping $1 discount!

From your email

You’ll receive an email that looks like this:

Choose whether to show each commenter’s number of approved comments, whether you’ll manually review all spam, and whether you’ll display a privacy notice, then click Save Changes.

Once Akismet has been running for a while, you’ll see some statistics like this (depending on which plan you chose).

#5. That’s it, you’ve installed Akismet!

Akismet immediately starts looking at the comments submitted to your site, and it sets aside the ones it identifies as spam. It will even notify you when there’s spam in the folder for your review!

Some WordPress site owners find this is all they need. Others find that, for one reason or another, they get more spam comments than they want to handle.

My suggestion is to wait a while. If you start getting a lot of spam and want something else to help reduce it, add a Captcha to your contact form. I’ll review that in another post.
