Research has shown that the reCAPTCHA field can be decoded by smart bots 99% of the time. Google has thus introduced a ‘No CAPTCHA reCAPTCHA’ API which has a risk analysis engine backing the verification process. Integrate this API into your Contact Form 7 forms, using this plugin. The Google No CAPTCHA reCAPTCHA plugin provides an option to set a custom error message when the CAPTCHA field is not set or if a robot is detected. The plugin is localization ready, which means you can display the error message in your local language. It also provides support to display the CAPTCHA in multiple languages. The plugin is multiform compatible. The plugin is multisite compatible. Do ensure that you add the keys for every sub-domain in the plugin’s settings.
