As the name implies, CAPTCHAs were created as a way for websites to differentiate a real human visitor from a bot. CAPTCHA forms allow webmasters to display an image which contains a random string of letters and numbers. Visitors to websites utilizing CAPTCHAs are then be prompted to correctly enter the text displayed in the image in order to proceed with certain actions such as registering a new account, or leaving a comment on a blog or forum.This is done in order to prevent bots from mass registering accounts, automatically posting spammy comments, and sending spam messages to a large amount of registered users among other things. CAPTCHAs have advanced over time to become less vulnerable to bots and scripts attempting to solve the codes while striving to remain user-friendly.
How CAPTCHA Advertising Works
The evolution of CAPTCHAs has inevitably led to a form of advertising. In essence, the core concepts and purpose of CAPTCHAs will remain unchanged. Don’t worry, you’ll still be shown an image that displays a line of text which must be entered correctly in order to proceed. The difference, however, lies in the presentation of the CAPTCHA. Instead of seeing a distorted image that contains randomly generated characters, you will see an image containing text that has been carefully selected by an advertiser.
These advertisers, which will likely span a number of big name national and international corporations, will submit their ads to a company capable of displaying them. Webmasters looking to monetize their CAPTCHA forms will also sign up with this company, and will be given a script that places the customized CAPTCHA on select portions of their website. The advertiser will then pay the said company a set amount of cash every time the CAPTCHA is successfully filled out, and the webmasters will be paid a cut of what the advertiser is paying. The company, acting as an intermediary, then collects the change remaining after paying out the webmaster.
