CaptchaAd WordPress Plugin


CaptchaAd is the first provider in the world to combine conventional CAPTCHAs (spam protection, of which around 280 million are generated worldwide every day) with high-quality video advertising. The novel aspect of the CaptchaAds is that concrete answers to a video clip, which can be made up of the product name, slogan or other keywords, have to be typed into the Captcha field instead of a random combination of letters and numbers. This makes the advertising message much more effective than other online advertising (100% contact with the advertising medium, extremely high advertising effectiveness).

CaptchaAd has applied for worldwide patents for this technology.

CaptchaAd offers an additional revenue stream for website operators and gives advertisers a completely new opportunity to carry out exceptionally efficient and measurable brand and product communications.

  • High quality video
  • Enhanced security
  • Greater usability for users
  • Better conversions
  • Additional revenue stream (optional)

CaptchaAd is not displayed properly

CaptchaAd is designed to work properly within WordPress standards. If you individualized your WordPress you might need to insert in the following Code-Snippet to your personal form-configuration.

$myCustomCaptcha = new Catchaad();
To check the answer: $myCustomCaptcha->checkAnswer();

Make sure that it is in place within the form and not just at the beginning of the code. This way you ensure that the CaptchaAd is displayed for example under the comment-box and above the submit button.


comments.php in the folder /wp-content/myTheme
