These websites range from less than 1 year old to over 5 years old. All forms were a collection of common information such as name, address, city, email address and a comment area. The study was done over the course of 6 months, half of the website started with CAPTCHA’s on and the other half started with no CAPTCHA’s. After 3 months the CAPTCHA was switched to the other CAPTCHA setting. I recorded the amount of successful, failed, and SPAM conversions for each of the 50 web forms.


A SPAM conversion was recorded when the submission had kuwait mobile phone numbers database excessive links or was a solicitation for a service. A failed conversion was recorded when a user/bot entered an incorrect CAPTCHA or never correctly entered the correct CAPTCHA after multiple tries. A successful conversion was when the information given in the web form was the required information minus any spammy information. On to the data!!!! CAPTCHA Turned Off 2,134 total conversions were entered while the CAPTCHA was off.


91 total SPAM conversions while the CAPTCHA was off. 0 total failed conversions while the CAPTCHA was off. CAPTCHA Turned On 2,156 total conversions were entered while the CAPTCHA was on. 11 total SPAM conversions while the CAPTCHA was on. 159 total failed conversions while the CAPTCHA was on. From the data you can see that with CAPTCHA on, there was an 88% reduction in SPAM but there were 159 failed conversions. Those failed conversions could be SPAM, but they could also be people who couldn’t figure out the CAPTCHA and finally just gave up.
