With the rapid growth of the WordPress community, WordPress websites have become one of the most attractive targets for spammers. Over the years, security experts have researched a variety of ways to control spam. Back in 1997, CAPTCHA was invented to distinguish between humans and bots.

However, CAPTCHA couldn’t keep up with the evolution of modern technology. The new bots would simply bypass CAPTCHA more often than not. As CAPTCHA became more complex, actual website visitors found it difficult to pass tests asking them to identify distorted letters to submit a form. 

After several iterations, Google introduced the Invisible reCAPTCHA to help control spam on your WordPress website. This free service uses advanced risk analysis techniques to tell humans and bots apart. You get notified when your site receives spam-like traffic, and your visitors get a positive site experience without the irritating tests.

Why Use Google Invisible reCAPTCHA?

WordPress website owners face many security threats, including spam comments, automatic fake registrations, and multiple login attempts. The original CAPTCHA fought against spambots by requiring visitors to answer a security question, but solving a challenge question became annoying to visitors. 

Google then created the reCAPTCHA v2 that allowed website visitors to simply click a checkbox to prove they weren’t automated spambots. While this tool was effective, Google decided to develop a more robust way to curb spam from behind the scenes. That’s how Invisible reCAPTCHA was born.

Invisible reCAPTCHA, also known as reCAPTCHA v3, uses an internal scoring system to detect abusive traffic on your website. That way, you can choose the most appropriate action for your website, like requiring email verification for risky site logins. This method also doesn’t interrupt the visitor experience with any unnecessary CAPTCHA questions or checkboxes.
