# Traffic quality and antifraud solutions

We strive to provide Yandex Direct advertisers with high-quality, efficient traffic from SSP partners. To monitor traffic quality, we use proprietary solutions powered by our antifraud system. All incoming traffic undergoes rigorous checks for fraudulent activity. Various antifraud rules let us catch invalid events early and respond accordingly.

Learn [how resource quality affects your revenue](https://yandex.ru/support/partner/en/efficiency/site-quality).

To improve the quality of your traffic and ensure steady inventory fill rates, follow these recommendations:
- Include UserIDs/IFA (GAID, OAID, IDFA, BUYERUID) in the request.
- Include `BidRequest.device.ext.ifv` for iOS traffic whenever IDFA is unavailable. 
- Include `BidRequest.device.ext.appsetid` for Android traffic whenever GAID or OAID are unavailable.
- If an SSP partner has a high percentage of unknown users and lacks IFA, you can explore alternative user identification sources, such as `appmetrica_id` (available upon request).
