The service is truly effective, as it eliminates not only clicks from fraudsters and competitors but also accidental clicks. In terms of its operation, it is practically no different from similar platforms (for example, ClickFraud): you need to install a js script on your site for traffic analysis, and then connect Yandex.Metrica and Yandex.Direct. All information is transmitted via API, allowing BotFaqtor to manage bids and prevent ads from being shown to unwanted users. Visitors are conditionally divided into three categories: bots, non-targeted, and targeted. The system generates reports on blocked users, where you can see keywords, UTM tags, and geolocation. Overall, I have no complaints about the blocked visitors. However, I have heard that some users report that BotFaqtor sometimes blocks normal traffic. Personally, I have not encountered this. I mainly use the service for Yandex.Direct, but it also offers solutions for Ads, anti-bot protection for websites, and banner protection.
