How to use Google reCAPTCHA to prevent spam on your website

What is Google reCAPTCHA?

Google reCAPTCHA is a tool developed by Google, that can help prevent spam on your website and ensure that your visitors’ information is safe and secure. As the internet grows, so also is the problem of spam. Spam can take many forms, from unwanted email messages to comments on blog posts.

Attackers also try to infiltrate websites by spamming contact forms, comment forms, and other web forms. With Google reCAPTCHA however, you can protect your website from spam and abuse. Google reCAPTCHA is a free service that uses advanced technology to distinguish between humans and bots, allowing only legitimate visitors to submit information on your website. In this article, you will learn how to integrate Google reCAPTCHA on your WordPress website so that all forms like your login, register, forgot password, and comments form can be secure from spam.


How does it work?

When it comes to using Google reCAPTCHA, there are two types of this powerful tool to choose from: reCAPTCHA v2 and reCAPTCHA v3.

reCAPTCHA v2 is the traditional checkbox-style CAPTCHA that requires users to check a box to prove they are not a robot. This version is easy to use and implement, making it a great choice for most websites. It also includes an “I’m not a robot” challenge that asks users to identify images or solve puzzles to confirm their humanity. There is also an invisible version of the reCAPTCHA v2.

On the other hand, reCAPTCHA v3 is an invisible CAPTCHA that runs in the background of your website and automatically identifies and blocks suspicious traffic. This version is ideal for websites with high traffic volumes, as it doesn’t require any user interaction and won’t interrupt the user experience.

The choice of which version to use depends on your needs. In terms of user experience, some users might find the traditional “I’m not a robot” challenge very intrusive and might find the invisible option more convenient. The invisible reCAPTCHA can however raise concerns about privacy and data collection since it depends on analyzing user actions and patterns on the website to determine if they are bots or not.

It is therefore recommended that you balance your need for security with ease of use and engagement and also be cautious of privacy and data collection concerns that any version you choose might pose.

There are many reasons to use Google reCAPTCHA on your website. Here are just a few:
