Why Use Captcha?

There are many reasons why you might want to use Captcha on your website. For one, hackers can be kept out of your website, and it can prevent them from adding lots of content to your website that can detract from the look and professionalism of your website. This can include comments that look dodgy and links that can be harmful to your customers.

Captcha can also improve the security and protection of those shopping on your website and can improve the trust you have with your customers.

Finally, you can also improve the integrity of your website. When you run polls or have analysis, you can reduce the fake responses and entries on your website. This can also save you time on contact forms.

Limitations of Captcha

However, there are some Captcha limitations. The first is that the bot that is accessing your website is not familiar with the post URL and fills the data instead of posting to the post URL. Another problem is that the bot needs to use JavaScript.

Also, it doesn’t provide your website with protection from those who are manually trying to spam you or attack your website.
