What is a spam comment?

A comment is considered as spam only when it doesn’t add value to the page where it was published or it made no sense based on the topic or context of the website but just to stuffing website links everywhere of webspace.

How to stop this comment spam and the spammers? Well, let’s read on.

We all love to see our comment box with zero spams.

I think, it’s not only me but any bloggers of this world really hate comments spammers; to be honest!

But, there is no plugin I found which can make a complete shield to those bot spammers. I tried with some other popular plugins available out there. Nothing really worked for me 100%.

But Google actually made a way to rescue us from any sort of website spams where the end-users are responsible for building them btw.

It is Recaptcha.

Google Recaptcha not only prevents comment spam but also protect your website from any kind of form spamming like spam on Contact Form, Spam on Registration and Login form as well.

Step by step Guideline to Integrate Google’s ReCaptcha in your WordPress Blog

Step 01: Download this Free Simple Google Recaptcha Plugin (it’s updated often and to me, the easiest one to use). And then install it on your WordPress site and activate it.

Step 02: From your WordPress dashboard; click on “Settings” and then click on “ReCaptcha” to open up their settings page. Keep this tab opened and move to the next step (we will come back here later).

Step 03: Click on this Google Captcha page (you may need a Gmail account to sign in) and give it a name in the Label section. Check the mark in “reCAPTCHA v2” from Recaptcha Type and then also click to the “I’m not a robot” Checkbox.

Step 04: Add your website (without https, just the domain name) on the “Domains” section.

Step 05: Click on the checkbox at “Accept the reCAPTCHA Terms of Service‘ and click on that big blue “Submit” button.

Step 06: On the next page you will find Site Key and Secret Key. Just copy them one by one and paste them into your WordPress settings showed at Step 02 above. And save the settings. Bingo!

The Recaptcha feature should be showing up on your blog under your comment section/registration form/contact forms from now on.

You can check your posts or pages from other browsers where no-cache/cookies are stored to see the Google Recaptcha live in action.

From now on, if anyone wants to publish a spammy comment; they have to match either an image or solve mathematical puzzles. The spammer’s bot doesn’t have that much intelligence to solve these automatically! So you are safe from any spamming ahead.

And what about the real users and commenters? They can easily comment on filling captcha as well because they love your content and really wants to share something that adds value!

How To Stop Spam Comments in WordPress

Whether we are a Webmaster or an SEO Expert managing clients or own websites or have a YouTube channel or some pages on social media websites; we all are to deal with spam comments, everywhere in web space.

I mean, comment spammers are all over the Internet. With due respect to the good commenters (who really adds value and genuinely ask questions/share opinions on comments), its really a high time to stop those spammers and keep the internet neat & clean. Because it’s easy to stop those junks in 2019 as lots of plugins, hacks and tweaking WordPress codes available!

Here is a step by step guideline to preventing comment spam (for WordPress Site)!

Step 01: Install Akismet Plugin and connect with their API to block the spam comments automatically.

Step 02: Go to the settings from WordPress Dashboard and click on discussions tab and “Check” mark on following options –

  • Comment author must fill out name and email 
  • A comment is held for moderation
  • Comment must be manually approved 

Checking those options will definitely reduce spam commenting as the spam bots look for the pages/websites those have these options unchecked. Now scroll below the discussion page and proceed to step 3.

Step 03: Go to the comment moderation section and set the value 1 to the line at “Hold a comment in the queue if it contains 1 or more links.” If you set 1, and if anyone wants to publish any comment with any links on the comment body; their comment will automatically be detected as spam and will be thrown away to the spam folder.

Step 04: Add some spammy words on the comment backlist section. Okay, what should you be adding there? Here are some suggestions (based on my experiences about dealing with all those spammers throughout the years) –

  • porn
  • adult
  • gambling
  • lottery
  • sex
  • livecam
  • hdcam streaming
  • lesbian
  • weapon

Step 05: Use Google’s Recaptcha in your comment box (you can do it using a plugin). Follow the link above and download the plugin and install it on your blog. Just go to the plugin setting and run their installation wizard to get the Google’s recaptcha api and integrate it on your site. Its so easy to follow and require couple of minutes to get it done.

I personally follow these steps on every websites/blogs I own and I am pretty much safe from comment spammers no matter how expensive bot they use. 🙂

Hope, you will find this tutorial useful. Keep spreading the knowledge. 🙂

Not all Captcha Plugin may suite your site. So, I would suggest you try Google’s Official Re-captcha system first with the Simple Google Recaptcha Plugin and then try with any of the plugins mentioned above.
