How can marketers protect against ad fraud?

Marketers can protect against ad fraud by using tools like IPinfo to block suspicious traffic sources, identify VPNs and proxies, and verify geographic alignment. Combining IP data with behavioral analytics gives teams a powerful way to ensure ad delivery integrity.

How to detect ad fraud?

Ad fraud detection often starts with recognizing irregular traffic patterns, like spikes in impressions from unfamiliar ASNs or click activity from anonymized IPs. IPinfo's real-time detection flags these anomalies early, so you can act before damage is done.

How to prevent click fraud?

To prevent click fraud, use IP-based filtering to suppress risky traffic before bids or clicks register. IPinfo detects click fraud by analyzing real-time IP data for signs of anonymized traffic, such as VPNs, proxies, and hosting providers, then flagging that data. These insights can be used to suppress fraudulent clicks before they register, protecting your budget and improving campaign accuracy.
