Enabling both comments and contact form messages on your page is one good way to improve your visitors’ engagement rate. Unfortunately, they are prone to spam messages, usually consisting of random advertisements and suspicious links that direct you to irrelevant websites.
If left unattended, spam can negatively affect users’ experience and harm your search engine optimization (SEO) effort. Web crawlers see spam comments as red flags, and Google might even remove the content from its search results.
One effective way to block spammers from your WordPress site is by installing an anti-spam plugin, like Akismet Anti-Spam by Automattic. This article will answer everything about the plugin, including what it’s used for, key features, and the installation process.
The Akismet Anti-Spam plugin is a cloud-based application that filters out spam on your WordPress website. Developed by the same company behind WordPress.com, this plugin has garnered more than 5 million downloads.
Akismet offers several prominent features, such as:
Akismet identifies spam comments from across websites using anti-spam algorithms. Every time a user posts a comment, Akismet examines it based on its database. If the algorithms identify a comment as spam, it will be removed from your website.
The algorithms also learn from actions taken by users to spot spam email addresses. For example, when many users report a specific comment as spam, Akismet will automatically tag it as spam.
In addition, Akismet allows users to filter out comments manually – the algorithms will then record this action and use it in filtering real users’ comments from the spammy ones.
However, there are times when the algorithms accidentally identify legitimate users as spammers. This issue occurs when a user’s comment is marked as spam on other sites, resulting in false positives. To prevent this from happening, check your moderation queue regularly.
If you don’t want to activate an anti-spam plugin, you can perform manual comment moderation to prevent comment spam on your WordPress website. That said, it’s a time-consuming process and is prone to human error.
For this reason, installing a plugin is a better alternative. The tool can quickly identify hundreds of comments, forms, and messages and then eliminate the ones that include spam.
Akismet Anti-Spam is our top recommendation among other spam-blocker plugins. Here’s why:
Thanks to its wide variety of features that cut down on manual comment moderation, Akismet allows you to focus on creating content and managing the rest of your website.
Akismet Anti-Spam also offers a freemium pricing model, with users being able to purchase premium features to boost its performance. There are dedicated plans for both personal and commercial use, starting from $9.95/month.
Akismet Anti-Spam comes as a default application with a WordPress installation. However, the plugin needs an API key upon activation. The following sections will walk you through an easy way to set up Akismet and get it running on your site.
If the plugin is not already installed on your WordPress site, proceed to locate it in the plugin directory.
An API key works as a password for your Akismet account, and it helps the server recognize you as an authorized user.
With that in mind, it is essential to maintain your API key’s security to prevent any misconduct.
Users can use the same API key for more than one WordPress site, depending on the subscription plan. To get yours, head over to Akismet’s main website.
Once the email has been verified, Akismet will then send a message containing your API key. Follow these next steps to connect your WordPress site with Akismet Anti-Spam.

Akismet Anti-Spam has now successfully been added to your site. The plugin will automatically start scanning for spam through your comments and forms as soon as it is activated.
