Not all impressions reach the web visitor, and not all clicks are real. Some publishers try to harvest publisher earnings from advertisers with questionable methods and technologies. Estimated 20% of all money invested in online advertisement, is spent on fraudulent clicks and unverified impressions. With our Adsata Fraud Inspector® we are in possession of very advanced filter technology in order to detect fraudulent web traffic. We do pre-bid and post-bid calculations based on data of incoming traffic. This fraud filtering happens on IP level, on user level and on browser level. This way Adsata provides a healthy eco-system built around online advertising.
