There is a quiet frustration that comes with a cluttered inbox. You see a notification, hoping for a new lead or a heartfelt message, only to find another automated bot trying to sell you something you don’t need. It’s more than just “junk”; it’s an invasion of your digital workspace.

Step 4: Connecting the Keys

To link your WordPress site to the global security network, you’ll need your Site Key and Secret Key.

  • Paste your keys into the designated fields.

If you don’t have your keys yet, we’ve made a simple Step-by-Step Google reCAPTCHA Key Guide for you.

Step 5: Global Reliability (Load From)

Spam is a global issue, so your defense needs to be global, too. Under the Load From setting, you can choose:

  • google.com: The standard choice for most users.
  • recaptcha.net: A critical alternative if your visitors are in countries where Google is restricted.

By selecting recaptcha.net, you ensure that your “I’m not a robot” box always appears, no matter where your audience is located.

Step 6: Total Site Protection

Now, decide which doors to lock. Hizzle CAPTCHA allows you to protect every corner of your site. Scroll down to the Display section and check the boxes where you want to show your reCAPTCHA.

Click Save Changes. Your site is now protected.

Why Pro is the Ultimate Experience for Your Visitors

The Challenge V2 checkbox is a powerful wall, but it does require a “stop and click.” If you want your visitors to feel a sense of absolute “flow”, where they move from browsing to contacting you without a single interruption, you need Hizzle CAPTCHA Pro.

The Pro version unlocks Invisible reCAPTCHA V2Score-based reCAPTCHA V3, and Cloudflare Turnstile.

The Pro Difference:

  • Invisible Harmony: Security happens in the background. Your users never see a checkbox or a puzzle—they just see your content.
  • Frictionless Conversion: Fewer clicks mean more sign-ups and more sales.
  • Smarter Detection: Pro features learn user patterns, making it easier for humans and impossible for bots.

Don’t let security get in the way of your connection. Protect your site silently, so your visitors only feel the ease of your brand.
