Why IP Reputation Matters for PPC: Invalid clicks from bots, click farms, or competitors can significantly waste advertising budgets. IP reputation is a key signal for identifying this fraudulent traffic at its source. Unlike generic IP reputation tools that rely on public threat intelligence which can lag behind real attacks, ClickGuardian's approach is different. We operate a dedicated fraud detection engine across live Google Ads and Microsoft Ads traffic, scoring every click in real time. This allows us to identify IPs that have misbehaved specifically within the context of paid advertising.

How it Works: Simply submit an IPv4 or IPv6 address for an instant response from our edge cache. The IP is then scored using a combination of geo, network, anonymizer, and first-party ClickGuardian network signals. You receive a verdict, a risk score, and detailed insights into the fraud signals.

Use Cases:

• PPC Managers: Investigate IPs from invalid-click reports to add to exclusion lists.

• Agencies: Audit client reports and provide evidence of wasted budget.

• Security Teams: Get a second opinion before allowlisting an IP in your WAF or CDN.

• Developers: Integrate into your stack via the API for seamless reputation checks.
