“CAPTCHAs” are programs designed to protect websites from being hammered by spam bots and abusive scripts, slowing them down and detrimentally impacting website performance for legitimate visitors (humans).
Until three years ago, CAPTCHAs were cryptic and often difficult to read boxes of distorted text which websites required you to decipher and then retype to prove you’re a real human, like the example below.
A welcome advance came in 2014 when Google introduced “No CAPTCHA reCAPTCHA”, replacing distorted text challenges with a simple “I’m not a robot” checkbox for validating users.
With a single click, website visitors could verify they were humans and not bots. This was a big improvement over the fuzzy text in a box that frustrated and infuriated real humans, especially on mobile devices.
While this was a big improvement, these CAPTCHAs can still be somewhat intrusive and impede user engagement on websites.
The good news is that Google has continued to work on improving their reCAPTCHA technology and this week released its new Invisible reCAPTCHA.
The end result is that visitors seamlessly pass a security check without even knowing it. This is especially important on mobile websites where, until now, reCAPTCHAs have interrupted user flow by taking up precious screen real estate on check-out and sign-up pages.
reCAPTCHA is a free service from Google that protects your website from spam and abuse. Register your site here and get the code which is straightforward to implement.
If you have a WordPress site it’s even easier using a free plugin. Invisible reCaptcha for WordPress has options to enable protection on the WordPress login, registration, comments, and forgot password forms. It’s also compatible with WooCommerce.
Finally, in the unlikely event it ever comes up as a question in Trivial Pursuit or a pub quiz, CAPTCHA is an acronym for “Completely Automated Public Turing test to tell Computers and Humans Apart”.
