【2026年版 アドフラウド実態調査】Web広告不正クリック対策、広告運用担当者の約4割が"見かけのCPA悪化"を理由に対策を躊躇・中止していることが判明

▤ Summary

Cacco surveyed 400 web advertising operators and found high awareness of ad fraud (75.8%) with 69.3% viewing it as a compliance risk and 36.8% reporting direct damage. Roughly 80% of victims lost between 1–20% of ad spend to fraudulent clicks, and 39.0% of respondents said they hesitate or stop countermeasures because mitigation can make CPA look worse. Responsibility for countermeasures is often unclear: 42.8% rely on agencies and 33.8% report no clear internal owner. Cacco says it launched the X-log ad-fraud protection service on April 1 to help resolve the operational dilemma and calls for executive-led efforts to improve transparency and true ROI measurement.
