11 Best WordPress AntiSpam Plugins! 2022

Did you start a blog a few months ago and now it’s getting both lots of traffic and lots of comments? Have you created a contact form where you should receive important messages, but only receive spam?

All of this can be solved by using some plugins from the list. We selected 10 plugins and ranked them in order of importance.

I recommend that you download a maximum of 2 plugins, no more. Because they could slow down the site excessively for the user. I’ll give you an example: WordFence is probably the most powerful plugin on the list, but we download and use it at times.

On WordPress, it is said that more than 3 million users use it. Which is good news on the one hand, but on the other it means that 3 million users are slowing down the site when they could be activating it once a week.

Why Use WordPress AntiSpam Plugins?

Plugin AntiSpam WordPress

They increase SEO:  when Google ranks your site, it checks internal links, comments, and even text (besides many other things, I want to focus on comments). If you see low-quality comments that might bother certain types of users, try penalizing the site and get those sites clean and spam-free first.

Time saving:  If you want to write the best articles in the market, you will need a lot of time. You can’t deal with comments and articles at the same time. Anti-spam plugins will make you have to take a look at the day and end (just to see if everything is working perfectly).

Improve the loading speed  : unless you use the Lazy Load of comments, each time a user enters the site, he will have to load both the text of the comment (which weighs little) but also the avatar (user image). Which weighs on average at least 10 KB.

Multiply 10 KB by 50 comments, it’s almost half a mega (minimum as we said) and more importantly it’s 50 requests to the server. In short, you can slow down the site by 2-5 seconds.

Maintain Website Reputation:  As we mentioned earlier, some sites prefer to remove reviews as long as they don’t lose their reputation, but that doesn’t allow them to grow higher on Google. The solution is to use AntiSpam plugins.

After all this long introduction, let’s start talking about the best WordPress Antispam plugins 2020.

Akismet

Akismet

It’s impossible not to know about Akismet if you’ve been using WordPress for a while. It’s an antispam plugin developed by Automattic (that’s right, those who developed WordPress).

Akismet is one of the most popular plugins out there, in fact, it has over 5 million active installs.

Since most spam comes from comments, Akismet monitors the comments section of your website very carefully. Automatically checks all comments and separates comments suspected of being spam from useful comments that are published immediately.

It’s very simple to set up. In fact, you just need to go to the Akismet site  , register and then they will offer you API keys. These will need to be added in the Akismet WordPress plugin. 

Unique Features  :

  • Easy to use
  • Compatible with major WordPress plugins
  • Advanced comment filter
  • Very powerful
  • Provides API key for websites

Best for:  WooCommerce and blogs that get lots of comments

Price  : Free, Pro version starts at $5.

Antispam Bee

Antispam Bee

If you want an antispam plugin that does its job immediately without any user registration, AntiSpam Bee might be your best bet. It’s a completely free plugin, and no matter what type of website you use, it will help you eliminate spam. 

AntiSpam Bee has many features to create a safe website for you. It can block comments from IP addresses, languages ​​and even countries to prevent spam from entering your website. You will also receive the number of blocked spam comments by e-mail each day.

Besides, you can also add an approval limit to comments and pings. It will automatically delete other types of comments. If you wish, you can also exclude trackbacks and pingbacks from spam detection. 

Another really useful function is the one that allows you to see in certain databases if an IP address has been marked as spam. If so, the user’s comment will be blocked until we provide consent.

Wordfence

Wordfence

Wordfence is the most used plugin on the list after Akismet. Over 3 million downloads. It is updated monthly in the WordPress dashboard, but its codes change much more frequently.

In fact, this plugin is the most comprehensive on the list. Not really! There is no comparison. Block users, bots, block anything you can think of. However, all of this has one flaw, site speed.

I realized that the plugin weighs down the site while being compatible with caching plugins. The advice I can give you to my clients is to install it once a week to do some checks.

In fact, it allows you to check if there is a virus on the site, if something is malfunctioning, it is a perfect plugin for protection against spam, malicious traffic, Brute Force attacks. It will carefully check your website by analyzing the content of your files, posts and comments.

CloudFlare

CloudFlare

Cloudflare is not actually a plugin, but a service available for free (it also has a paid version but you won’t need it).

I leave you this article so that you can learn more. But what you should know is that it acts as a content delivery network.

Yes, I know it’s not clear so I’ll try to use simpler language. In short, if you have hosting, you will have servers. These servers are located in some countries, ours is in Germany. A user who wants to see our site will have to make a request in Germany.

This is very bad for users who may be living in the United States. Cloudflare will offer you more than 200 servers. Do you think they have 2 servers in Italy, Milan and Rome. All of this could speed up the site.

For most people, this is the best choice. However, we use it on client sites but not our own because it was developed to be very fast and because we would like to transfer it to  Kinsta  . They have a proprietary CDN which works differently than Cloudflare but we like it more in turn.

But what should interest you is that Cloudflare blocks all types of spam from bots, since the traffic will pass through their server, they will be able to recognize spam from real users.

Unique characteristics:

  • Protection against DDoS attacks
  • CDN
  • Advanced Web Application Firewall (WAF) Security

Some tips to avoid spam

A few years ago, the famous billionaire and philanthropist Bill Gates said that within 2 years, all spam circulating on the web would be over. If you’re reading this article, that means spam hasn’t gone away at all. Peach.

But it’s also true that technology has advanced and it’s now much easier to stop spam, as we’ve seen.

Let’s see some tips to avoid spam:

  • Using a good hosting, we always recommend Kinsta to everyone because they have developed anti-spam software similar to CloudFlare  (level is not the same, but for over 85% of people it will be fine)
  • Always update WordPress as plugin code errors or outdated themes are often used
  • Block IP addresses that have left spam in comments or contact forms
  • Never open links left in comments by spammers as they may steal your WordPress site data 
  • Create a list of blacklist words, if you go to WordPress, settings and finally comments, from there you can put all the banned words

Conclusion

As the owner of several WordPress sites, I think the choice of antispam plugin for WordPress depends on the characteristics of the traffic you receive.

We also showed you that each plugin is great for different sites. Either way, I recommend using CloudFlare  with  Akismet  . Believe me, this will block all spam.

For those who realize that it is not enough because maybe he receives many visits. Then he will have to check if he receives more spam from bots or users.

In the case of bots, the best choice is the  Blackhole for Bad Bots plugin  , in the case of your competitors,  Stop Spammers  might be the best choice.
