PPCmate filters traffic quality at two levels:
Publisher/supply-side enforcement. Every SSP and publisher sending traffic into PPCmate must meet strict quality standards before their traffic is accepted — no bots, proxies/VPNs/datacenter traffic, incentivized clicks, spoofed domains, or non-human sources. Traffic must be at least 90% human based on industry-standard fraud detection, and non-compliant sources are filtered automatically or removed. See Minimum Traffic Standards & Compliance Requirements for Publishers for the full policy.
Campaign-level protection. You can enable the Escalated.io traffic-quality integration on a per-campaign basis in your campaign settings for an additional layer of fraud detection on your own traffic.
Is PPCmate traffic AdSense-safe? Yes — see Is your traffic AdSense safe?
If you suspect a specific source is delivering low-quality or fraudulent traffic to your campaign, contact support with your campaign ID and any supporting data (referrers, IPs, timestamps) so it can be investigated.
