How to turn on Google reCAPTCHA on your forms
Go to Website, then SEO, and switch on Google reCAPTCHA on your forms; visitors then tick “I’m not a robot” before sending a contact or alert form.
Your forms are already protected by a built-in spam filter. reCAPTCHA adds an “I’m not a robot” check for websites that still get a lot of spam.
