Security has been a significant concern in ecommerce due to the amount of sensitive customer information each online store needs to collect and process.
An increased number of areas where customer action is required has made ecommerce websites an attractive target for hackers. From registration and contact form spam to spam orders — WooCommerce store owners have been battling malicious activity on their websites for years.
Adding Google reCAPTCHA to your WooCommerce store
Along with web application firewalls, using Google reCAPTCHA is one of the ways you can protect your ecommerce website from spam bots, thus significantly reducing the possibility of it being exploited. In this Nexcess Knowledge Base guide for WooCommerce, you will learn what Google reCAPTCHA is and how to add it to your WooCommerce store.
What is a CAPTCHA?
CAPTCHA, which stands for Completely Automated Public Turing Test to Tell Computers and Humans Apart, is a security measure that can be added to various website areas to challenge visitor traffic. In simple words, a CAPTCHA is a way to determine if a website visitor making a specific request is a human and not a bot.
CAPTCHAs provide a high level of protection against malicious requests made by spam bots by ensuring challenge-response authentication. There has been, however, a lot of discussion about it providing a terrible user experience, which has led to some well-known ecommerce websites reducing the number of CAPTCHAs in use.
Are there any alternatives to CAPTCHA?
However, whether traditional CAPTCHAs should be replaced with other web traffic challenge solutions remains an open question, as the other options are based on blocking and allowing traffic, which inherently leads to an increase in false positives and false negatives.
Google reCAPTCHA v2 provides more of a traditional CAPTCHA test, while the release of Google reCAPTCHA v3 was a great step towards more of an interactionless website user behavioral goal.
Google reCAPTCHA as a replacement for traditional CAPTCHAs
reCAPTCHA is a free service offered by Google that you can integrate with your website to secure your WordPress or WooCommerce website and significantly reduce the attack surface. Google reCAPTCHA uses better risk analysis technologies, making the challenge it provides more advanced than the typical CAPTCHA tests.
Google reCAPTCHA v2 vs. Google reCAPTCHA v3
Google reCAPTCHA v2 and Google reCAPTCHA v3 are the two versions of the service that provide different approaches to the visitor traffic challenge. reCAPTCHA v2 offers three ways to challenge web requests, each based on the user performing a certain task. As the same time, Google reCAPTCHA v3 requires no user interaction to verify the legitimacy of a request.
Google reCAPTCHA v2: types of challenges
Google reCAPTCHA v2 provides two main options for challenging user requests on all websites:
- "I am not a robot" checkbox. The checkbox requires the website visitor to click a checkbox indicating the user is not a robot. This option is the simplest to integrate into WordPress and WooCommerce.
- Invisible reCAPTCHA badge. This challenge type does not require website visitors to click on a checkbox, instead, it is invoked automatically when the submit button is clicked, which would result in the user posting a comment, submitting a contact form, or placing an order.
Google reCAPTCHA v3: relevant details
Using Google reCAPTCHA to protect your WooCommerce store
A CAPTCHA, including the Google reCAPTCHA service, can help protect all areas of your WooCommerce store that involve user action. Here are the three main issues that reCAPTCHA can address by reducing the number of malicious requests making it to the web server:
- Unauthorized login attempts, including abusing the password recovery option.
- Spam sent from contact and registration forms.
- Fake registrations and spam orders.
Two ways to integrate Google reCAPTCHA into WooCommerce
Regardless of the version, Google reCAPTCHA provides an outstanding level of protection against spam of all kinds for your WooCommerce website. In addition, Google allows you to add reCAPTHCA to your website manually by making adjustments to its code. This option might be preferable if you are familiar with WordPress development.
Another way to integrate Google reCAPTCHA with WooCommerce is by using a WordPress plugin. In addition, there are quite a few free and paid solutions that allow you to use reCAPTCHA with your online store.
