Do you have a contact form on your website? If so, you may have noticed spam messages being submitted through your form. Captcha is a great solution to prevent unwanted spam messages from being submitted. The purpose of Captcha is to ensure that the visitor filling out your contact form is actually human and not a computer program. There are many different types of Captcha tests. Some of the most common methods of Captcha tests require users to type in the letters and numbers they see in a distorted image. They also let you calculate a simple math equation, or select images containing a certain object, like a bicycle or stop sign. More recent and advanced methods of Captcha protection work behind the scenes to verify the user is not a bot, giving legitimate users a seamless experience while blocking the bots.
