How to use Google reCAPTCHA to protect websites from spam messages, I believe many inexperienced people are at a loss about this. Therefore, this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

If you allow users to post content on your site, such as leaving comments and creating user profiles, you may see that spammers try to use these channels to create traffic for their own sites. It is not pleasant for anyone to have such spam messages on your website. Users may encounter annoying ads that lead them to vulgar or dangerous sites that contain fraudulent content or malware. As a webmaster, you may violate the content of the webmaster's quality guide and affect your site's position in the search results.

There are some ways to solve this problem, such as reviewing comments and reviewing new user accounts, but the number of spam messages is often too large to review. Spam messages can easily reach an uncontrollable number because most spam messages are not created manually by their disseminators. Instead, spammers use a computer program called "bots" to automatically fill out web forms to create spam messages, and these bots generate spam messages much faster than human censorship.

To create a level playing field, you can take steps to ensure that only people can use features on your site that are likely to generate spam messages. One way to determine which visitors are human is to use CAPTCHA, the fully automated Turing test that distinguishes computers from humans (completely automated public Turing test to tell computers and humans apart). A typical CAPTCHA contains a distorted letter picture that humans can read, but computers cannot easily understand. Examples are as follows:

By using Google's free reCAPTCHA service, you can easily take advantage of this technology on your own website. What is unique about reCAPTCHA is that the data collected by the service is used to improve the process of scanning words such as books or newspapers. By using reCAPTCHA, you can not only protect your website from spammers, but also help us digitize books around the world.
