I was very happy to see Google rolling out this “no-captcha” API that allows webmasters to no longer have to show that ugly and conversion-killing captcha script to authenticate human users vs. bots.
CAPTCHA has been my pet peeve for years. Although I have not run across statistics on it, I believe that CAPTCHA has a dramatic effect on user experience and contributes to significantly higher levels of abandonment.
In the beginning, CAPCHA wasn’t terrible. Most people can add 5+4. But, now, it has become ridiculous in an effort to combat more complex bots. Glad to see this development and very excited to see this implemented.
