What is Akismet and Why You Should Start Using it Right Away

Every WordPress installation comes with two plugins pre-installed. One of them is Akismet, which is definitely in our list of must have WordPress plugins. Even though Akismet comes pre-installed, it is not activated by default. You will have to take some extra steps to activate it. In this article, we will explain what is Akismet and why you should start using it right away. We will also show you how to setup Akismet on your WordPress site.

What is Akismet?

Akismet is a comment spam filtering service. The name Akismet comes from Automattic and Kismet. Auttomatic is the company behind Akismet, and it was founded by the WordPress co-founder Matt Mullenweg. Akismet catches blog comment and pingback spam using their algorithms. This algorithm learns from its mistakes and from the actions taken by participating websites. For example, when a number of websites start reporting similar looking content as spam, then Akismet will learn to identify that kind of content as SPAM in the future. As of June 14, 2013, Akismet has caught more than 83 Billion spam comments.

Why you should use Akismet?

On popular websites, the amount of spam comments could get as high as 85%. This means out of every 100 comments only 15 are legitimate. Comment moderation is a time consuming task, and Akismet can save you hours. Akismet will catch spam comments before it lands in your moderation queue as pending. This allows you to focus your energy on moderating comments by real users.

Criticism by Users

In the past users have criticized Akismet for giving false positives. False positives are legitimate comments that gets marked as spam by Akismet. This can happen for variety of reasons. One of the most common reason is if a user’s comment is marked as spam by a number of blogs, then Akismet would learn to mark all comments by that user as spam. Like any other automated platform, Akismet is not perfect, but it is the best there is.

How to Know if your Comment was Detected as Spam

If your comment was marked as spam by Akismet, then you will not see the Awaiting Moderation notice like you normally would. If you submit a comment on a site, and you do not see your comment text along with a notice saying awaiting moderation, then you should immediately contact the site administrator. They can help pull your comment out of the spam box, and overtime Akismet will learn from its mistakes.

  1. John Rajesh says:

    What are the Pros and Cons of Akismet Plugin?

  2. Jeffrey says:

    If my web doesn’t have comment and registeration section, do I still need Akismet?

  3. kalpesh says:

    HI Admin, I have one doubt is it a paid version or available for free of cost??

    • WPBeginner Support says:

      It is available for free and optionally if you like it you can choose to pay for it.

  4. Ralph Musgrave says:

    Akismet is a pain in the whatsit. It keeps classifying me as spam.

  5. KristiGarrett says:

    What does Akismet look like to the user? Can they sign in using multiple options (Disqus, Facebook, Twitter, Google+) like you do here?

    • WPBeginner Staff says:

      Akismet is a spam filtering system not a commenting system. It works in the backgrouns and not visible to your users.

  6. RW says:

    Akismet is an awesome plugin. I do agree with some of the other posters here that it’s worth pointing out that it is not free. The Editors point out that it’s free for personal, non-business blogs, but I don’t believe the majority of your readers are interested in personal, non-business websites.

    I was saddened when Akismet went the paid route, but I understand. It’s a great plugin if you have the budget for it…

  7. John Brinkley says:

    What does the ‘Filter’ button do between ‘Show all comments’ dropdown box and ‘Empty Spam’ button?

  8. Justagurlinseattle says:

    This Akismet is marking almost every reply I write as spam.

    It is getting rather frustrating. I see that they like to keep a running count as to how
    much spam it is blocking, however, if 8 out of 10 of my replies are being marked as spam,
    this is a highly inflated number of comments that are not spam.

    I tried using my wordpress account to log in and make my comments, this did not work,
    so I tried logging in via my Twitter account, this also did not work.

    The Admins inform me that they are not able to retrieve my comments.

    Can you help me???
    any suggestions as to what I should do????

    any suggestions as to how the Admins of that blog can release my comments????

    • WPBeginner Support says:

      Contact Akismet support. Your comment is not marked spam for no reason. For example, if you comment on and a moderator thinks that your comment is spammy and marks it as spam. Then your future comments on will automatically go to spam. Until an admin or moderator on looks into spam and unmarks your comment.

  9. Dineen Miller says:

    I made a query at the Akismet site but didn’t get an answer so maybe you can answer my question? I’m looking at the Pro plan for my site but I want to know if commenters will be required to answer some kind of security question. Is this standard on Akismet? A feature we can turn on or off? Or does this plug in work completely in the background of the site? Thank you!

  10. Abdullah Munir says:

    Its not free which was worth mentioning.

  11. Betsy says:

    Does it bother anyone else that and are used interchangeably? I’m trying to figure out if Akismet works with but all I can find is that it’s a plugin available for .org. Meanwhile, you need to register in .com to get an API account. I have a blog through but since they don’t allow plugins, I can’t figure out how or if Akismet runs on Does anyone have the answer to this? Am I missing something?

    I know there is a widget that I can put on for Akismet but all it does is allow you to show it on your sidebar but it doesn’t actually do anything. Very frustrating!

    • Editorial Staff says: automatically runs Akismet. But if you want to register an API, there are more than one ways available now. You can go to the official Akismet site to apply for an API. Furthermore, you can also register a account without a blog, and get an API as well. although, the plugin must be enabled for it to run. It does not run by default like site does.

  12. Ethan says:

    There’s some changes with akismet. Now you can actually apply directly from akismet website.

  13. Ryan says:

    83% spam seems low to me. I would have guessed mid to upper 90s for the percentage of spam comments. But that would just be a guess and Akismet has the data to back it up.

    I’m always amazed how many people don’t know about Akismet when they setup a blog. Almost seems like it should be on by defaults and signing up for an API key should be part of the process setting up a new blog.

    • Editorial Staff says:

      Yeah even though Akismet comes bundled with WordPress, Many bloggers continue to ignore it because they do not know how to get this API.

      • Caitlin Dundon says:

        The thing that is currently confusing me is that I switched from to and I downloaded the plugin – but when I go to the Askimet site it asks for my login…which I still have, but I am not using that blog anymore since I am now selfhosted…Will that key still work with my selfhosted blog?

        • Editorial Staff says:

          This is a recent change that they made. The answer to your question is yes it will still work.

  14. Tim Live Chat says:

    Fighting spam is a must. My previous company has a forum. Guess PHPBB is too popular, we need to spend several hours per day to clean up the spam posts.

  15. Sergej Müller says:

    Please test – the simple antispam plugin for wordpress. It’s easy.
