ReCAPTCHA is an advanced version of CAPTCHA that can distinguish between robots and humans. CAPTCHA stands for ‘Completely Automated Public Turing Test to Tell Computers and Humans Apart.’ Users must check a box verifying that they are not a robot to pass the test. After that, they will either pass right away or be provided with a series of photos in which they must match the objects.

In this article, you’ll understand the step by step procedure to set up the reCAPTCHA WordPress Integration. You’ll also gain an in-depth understanding of both of these platforms and the features they offer. Finally, you’ll get to know how reCAPTCHA WordPress Integration can be beneficial for your business.

WordPress is a Free and Open-Source website creation and management application that allows users to create, publish, and manage content for their websites. It’s a straightforward CMS (Content Management System) that powers more than 40% of the top 10 million websites on the Internet. The most enticing aspect of WordPress is that it does not require users to have any prior coding knowledge in order to construct and maintain their websites.

WordPress offers drag-and-drop capabilities for creating a website from the ground up, as well as a large number of commercial and free themes that cover practically every topic.

It’s also SEO-friendly, so users can generate material that appeals to both visitors and search engines. It can be used to create Blogging Websites, Corporate Portfolios, E-Commerce Websites, and a variety of other things.

Key Features of WordPress

Let’s have a look at some of WordPress’ most important features:

  • Ease of Use: You don’t need any technical knowledge to design and maintain a WordPress website. The platform is easy to use and saves you time and effort as compared to building a website from the ground up.
  • Effective SEO Optimization: WordPress generates numerous SEO Signals for your content and ensures that it is SEO optimized automatically.
  • Themes: WordPress has a big number of useful themes that you can use to alter the look and feel of your website without needing to know how to code.

What is reCAPTCHA?

reCAPTCHA is a CAPTCHA technology that allows web hosts to differentiate between human and automated website access. Users had to decipher difficult-to-read text or match photos in the original version.

If the analysis of cookies and canvas rendering revealed the page was being downloaded automatically, Version 2 would also request users to decrypt text or match images. ReCAPTCHA has never interrupted users since Version 3 and is designed to run automatically when users load pages or click buttons. Google owns the reCAPTCHA service.

The 1st Version of the service was a crowdsourcing platform for digitizing books, especially those that were too unreadable to be scanned by machines. The verification prompts employed two words from scanned pages, one as a control for verification and the other to crowdsource the reading of an unclear term.

At Carnegie Mellon University‘s main Pittsburgh campus, Luis von Ahn, David Abraham, Manuel Blum, Michael Crawford, Ben Maurer, Colin McMillen, and Edison Tan created reCAPTCHA. In September 2009, Google purchased it.
