Hey there, fellow WordPress user! Let me ask you a question:
How much time do you spend moderating comments on your site? If you‘re lucky, maybe just a few minutes per day. But for many site owners, sorting through comment spam can feel like a full-time job.
It‘s a massive problem. Did you know that over 80% of all comments posted online are spam? Yeah, you read that right. Without strong protection in place, your site can easily get bombarded with thousands of spammy comments linking to shady websites.
But there‘s an unsung hero that has been fighting the good fight against spam for over 15 years: Akismet.
What is Akismet?
Akismet is the leading anti-spam plugin for WordPress and other platforms. It was created by Automattic, the company behind WordPress.com, Jetpack, WooCommerce, and other tools that power millions of sites across the web.
Since its launch in 2005, Akismet has been doing the hard work of identifying and blocking spam comments so you don‘t have to. It‘s used by over 5 million websites and has collectively blocked over 500 billion spam comments as of 2023. That‘s billion with a "B"!
Fun fact: The name "Akismet" is derived from "Automattic Kismet." Kismet means fate or destiny. So you could say Akismet was destined to save us from spam!
How Does Akismet Work?
So what makes Akismet so effective at catching spam? It all comes down to machine learning and big data.
Every time a new comment is posted with Akismet enabled, it gets analyzed by Akismet‘s sophisticated algorithms. These algorithms look at hundreds of factors, like:
- IP address and domain of the commenter
- Language and content of the comment
- Presence of hyperlinks, especially to blacklisted domains
- Frequency and volume of comments coming from that commenter
If a comment looks suspicious based on these factors, Akismet will automatically mark it as spam and filter it out of your pending review queue. The spam comments get stored in a separate spam folder for reference, but they won‘t clutter up your real comments.
The real magic is that Akismet is constantly learning and improving its spam detection abilities. It cross-references new comments against a global database of millions of known spam comments. So if a particular phrase or link starts getting flagged as spam frequently across many sites, Akismet will start preemptively blocking it everywhere.
Akismet currently blocks over 7.5 million spam comments per hour. That‘s around 180 million per day! Imagine trying to moderate that volume of junk manually. Akismet does that hard work for you silently in the background.
Akismet and Privacy
Now you might be wondering – how does Akismet handle user privacy? It‘s a fair question, since Akismet does collect some data about each comment in order to analyze it.
Specifically, Akismet records the following info for each comment:
- Commenter‘s name
- Email address
- IP address
- User agent (browser/device)
- Content of the comment
However, this data is only used for the purpose of providing the Akismet service and improving its spam detection ability. Automattic does not sell or share this comment data with any third parties, and they fully comply with privacy laws like GDPR.
Only the email address and IP address are sent to the Akismet servers for analysis. The other details stay on your own WordPress server. Akismet also has an opt-out mechanism for commenters who don‘t want their comments analyzed.
You can read the full Akismet privacy policy here for more details: https://akismet.com/privacy/
As a site owner, you are ultimately responsible for the data collected by tools like Akismet. I recommend disclosing your use of Akismet clearly in your privacy policy and giving commenters a way to opt out if requested.
Setting Up Akismet
Okay, you‘re convinced that Akismet is awesome and want to set it up on your WordPress site. Great decision! The setup process is quick and easy.
First, install the Akismet plugin on your site. You can do this by searching for "Akismet" in the Plugins > Add New section of your WordPress dashboard:
[Screenshot of Akismet plugin in Add Plugins screen]Once installed, click the Activate button. You‘ll then be prompted to enter an API key:
[Screenshot of API key prompt]An API key is a unique code that connects your WordPress site to your Akismet account. If you don‘t have an Akismet account yet, you can register for one directly from this setup screen:

The paid plans include advanced features like analytics, priority support, and the ability to automatically discard spam after a set timeframe.
Once you‘ve signed up for an account and have your API key, enter it back in your WordPress dashboard to complete the connection.
And that‘s it! Akismet will now be monitoring comments on your site and filtering out spam automatically. You‘ll see a notice letting you know it‘s working:

With Akismet activated, you shouldn‘t have to do much day-to-day spam fighting. However, it‘s still a good idea to check your spam folder periodically to make sure no valid comments accidentally got marked as spam.
You can review your spam by going to the Comments section of your dashboard and clicking the Spam link at the top:
[Screenshot of Comments screen with Spam link highlighted]If you see any comments that shouldn‘t be marked as spam, simply select them and click the "Not Spam" button to recover them. They‘ll go back into your regular comments folder.
You can also delete spam comments permanently by selecting them and clicking the Delete button. However, I recommend leaving them as spam instead of deleting. That way Akismet can continue learning from them to improve its filtering.
By default, Akismet stores spam comments indefinitely. If storage space is a concern, though, you can configure it to automatically delete spam older than 15 or 30 days in the Akismet settings.
My experience with Akismet
I‘ve been using Akismet on my WordPress sites for over a decade now, and it has easily saved me hundreds of hours of spam-fighting time. There‘s just no way I could have managed the volume of spam comments I was getting on my own.
One of my sites was featured on a major news outlet a few years ago, and traffic spiked to over 50,000 visitors per day. Of course, with that spike came a flood of spam comments – over 1,000 per day at the peak. But Akismet hardly let any of them slip through. I only had a handful of false positives to fish out of the spam folder.
Without Akismet standing guard, I shudder to think what my comment sections would have looked like. Instead of meaningful discussions, every post would have been swamped with junk about fake Rolexes and dubious pills!
So from one WordPress user to another: trust me, Akismet is absolutely worth installing. It‘s one of those plugins you set up once and let it do its thing. Your future self will thank you when you‘re not losing hours every day to moderating spam.
Akismet Frequently Asked Questions
Before we wrap up, let me address some common questions and concerns about Akismet:
Will Akismet slow down my site?
Nope! Akismet does its analysis on its own servers, not yours. So it has minimal impact on your site‘s loading speed and performance. I‘ve never noticed any slowdowns from Akismet across many sites.
Does Akismet work for comment registration spam?
Yes, Akismet checks all types of comments, including those left by registered users. It‘s not just for anonymous comments. However, it‘s still a good idea to require some kind of user verification (like email confirmation or CAPTCHA) to prevent fake registrations.
What if Akismet marks a real comment as spam?
Akismet isn‘t perfect and occasionally legitimate comments do get flagged as false positives. But in my experience, it‘s extremely rare – maybe one in a thousand. If it happens, just mark the comment as "not spam" to recover it. Akismet will learn from the correction to avoid similar mistakes in the future.
Are there any Akismet alternatives?
There are a few other anti-spam plugins out there, like Antispam Bee, CleanTalk, and Spam protection by CleanTalk. However, none of them have the longevity and massive dataset that Akismet has built up over the past 15+ years. That data is what gives Akismet its edge and accuracy. The other plugins are more prone to false positives in my experience.
That said, many sites use a combination of Akismet and other anti-spam measures like CAPTCHAs, anonymous comment restrictions, and IP blacklists for additional protection. But Akismet should still be your first line of defense.
The Verdict on Akismet
Is Akismet an absolutely essential WordPress plugin? In my professional opinion, yes.
I‘ve seen first-hand the chaos that comment spam can cause, and Akismet is hands-down the most effective, easy-to-use solution. It‘s a prime example of how machine learning and big data can solve messy problems and make our lives easier.
Of course, Akismet alone won‘t stop 100% of spam. It‘s still important to have smart policies around user registration, comment moderation, and IP blocking to keep your site clean. But Akismet will dramatically cut down on the spam and save you massive amounts of time and frustration.
So go ahead and set up Akismet today if you haven‘t already. Then pat yourself on the back for taking a big step towards a spam-free WordPress site!
