Google’s reCAPTCHA has long been the most common way to determine if a website visitor is a human user and not a bot. Until now, users checked a box or typed a series of characters correctly to proceed. But Google has just rolled out a new approach that won’t require users to interact directly with reCAPTCHA at all.

Google’s latest implementation uses advanced behavior monitoring so that the way a user navigates around a webpage will be enough to determine if they’re a real person. Further, every additional user will help Google better identify what actions characterize human visitors.

For ecommerce sites, this advance in reCAPTCHA technology can remove another checkout friction point, especially for mobile shoppers, and can help optimize your checkout. For more information on invisible reCAPTCHA, head over to Google.
