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

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.

How to Set up Akismet in WordPress

First thing you need to do is go to Plugins and activate Akismet.

Upon activation, Akismet adds a new menu item at Plugins » Akismet Configuration. Clicking on Akismet Configuration will take you to Akismet Configuration screen. On this page, you will be asked to enter your Akismet API Key. Leave this page open and open a new browser window. We will come back to this page after creating an API key for Akismet.

How to Get API Key for Akismet

In order to set up Akismet on your website, you need an API Key. Go to Akismet website and click on Get a WordPress Key Button.

This will take you to Akismet plans and pricing page. Akismet is free for non-business and personal sites. For business websites, there are different plans and packages available. Choose an option that best suits you. The pricing is setup on honor system, so theoretically you can get away by using a personal plan on a low traffic site. No matter which plan you choose the remaining steps will be similar. Click on the Sign up button to proceed.

Clicking on the sign up will bring you to the next screen where you will be asked to sign up with WordPress.com. WordPress.com is a blog hosting service by Automattic, the same company that brings you Akismet. However, WordPress.com is not the same as your WordPress.org self hosted website. You can create a WordPress.com account without creating a blog. Click on Sign up with WordPress.com button to continue. This will open a pop up window with a simple sign up form.

If you already have a WordPress.com account, then you can click on the link I already have a WordPress.com account. If you don’t have a WordPress.com account, then simply fill out the details and create one.

Once the authentication with WordPress.com is complete, you will be taken back to the Akismet website. There you will be asked to provide some user details along with the payment information. If you picked the free plan, then simply drag the price amount to $0.

Click the continue button and you’ll be taken to the screen that shows your API key. You will also receive an email from Akismet containing your API Key.

Remember, an API key is like a password. Do not share it with anyone. In case you lose or forget your API key, you can always visit Akismet.com and click on the sign in button to access your account page. After signing in you will see your Akismet API key hidden. Click on Reveal link to display your API key.

Showing Akismet Stats on Back and Front-end of your Site

After logging in to your WordPress website, you will see an overview of Akismet Stats.
