Since we are not pay-per-click advertising network, fake clicks don't affect advertisers' expenses. But they distort advertisers' statistics, that is why we implemented a new feature that enables our advertisers to filter out bot generated clicks via captcha.
Advertisers can specify the Captcha rate for their campaigns:
The default value is 0, but if you want to check all the visitors before they arrive to your site, you can set it to 100%.
Although some people might refuse to pass the captcha, we don't expect significant decrease of conversion since this kind of captcha is usually easy to pass. Here is how it looks like:
We expect a significant decrease of unique clicks registered by our servers because they will be filtered out by captchas.
