How much will I earn from the AdEmbed program?

AdEmbed is a pay for performance program, meaning that you will earn a commission when one of your readers completes a qualifying transaction on the advertiser site. Commissions vary from a flat fee to a percentage of the total sale.

How can I track performance, commissions earned, etc. for the AdEmbed program?

We are working on the back-end interface providing just such capabilities. In the mean time, contact BotProof Marketing (marketing@BotProof.com) and we will provide you with a custom report.

How and when will I be paid if I have opted-in to the AdEmbed program?

We will notify you when commissions earned have reached $20; and make payments to your PayPal account within 90 days of the end of the month when commissions were earned (assuming no cancellations, returns, charge-backs, etc. on the commissionable event).

Why do you use random letters and numerals, instead of words from the English language?

The captchas you see online who use words from the dictionary are doing so because their noise makes it too DIFFICULT for a human to read. (Noise is the distortion or lines they add to a particular symbol.) But using English words is less secure. Once a bot can guess a few letters, it can search for words in the dictionary to solve the other unreadable letters. Because BotProof Captcha does not need to distort the letters and can make them more readable, we can offer the added security of using random symbols. Our captcha also therefore does not depend on the user speaking a particular language.

Are captchas secure? I heard spammers are using other sites to solve them: the captchas are sent to a different site, and the other site's users are asked to solve the captcha before being able to enter or access a valuable resource.

Captchas offer great protection against abuse from automated programs. While it might be the case that some spammers have started using redirection sites to attack captchas (although there is no recorded evidence of this), the amount of damage this can inflict is small (so small that we haven't even seen this happen). Whereas it is easy to write a bot that attacks an unprotected site millions of times a day, redirecting captchas to be solved by humans would only allow spammers to abuse systems a few thousand times per day. The economics of this attack just don't make sense. Every time a redirection site shows a captcha before giving access to a resource, they risk losing a customer to another site that doesn't do this. We welcome references to any articles, evidence, or research in this area.
