2015 Bot Baseline Report Summary

Core Content

This report, published by the Association of National Advertisers (ANA) in collaboration with White Ops, provides a comprehensive analysis of bot fraud in the digital advertising ecosystem in 2015. It highlights the persistent and evolving nature of bot fraud, the financial impact on advertisers, and the need for a unified and proactive approach to combat it.

Main Findings

1. Bot Fraud is Widespread and Persistent

• No Advertiser Was Immune: All 49 participating advertisers experienced bot fraud, with the average bot rate declining only slightly compared to 2014.
• Bot Rates Vary: Bot percentages ranged from 3% to 37%, indicating significant variability in the effectiveness of anti-fraud measures across participants.
• Concentration of Losses: A small number of advertisers accounted for a large portion of the fraud losses, with 30% of advertisers responsible for 80% of the bot fraud in 2015.

2. Financial Impact of Bot Fraud

• Estimated Losses: The average annual loss per participant was $10 million, with global losses expected to reach $7.2 billion in 2016.
• High Impact on High-CPM Media: Display media with CPMs over $10 had 39% more bots, and video media with CPMs over $15 had 173% more bots.
• Hotspots of Fraud: Some advertisers faced losses of up to $42 million due to high bot percentages in specific campaigns.

3. Bot Fraud is Evolving

• Bots Evade Detection: Bot operators use complex techniques to avoid detection, including mimicking human behavior and using stolen cookies.
• Shift in Targeting: Bots have shifted from targeting display to video, driven by higher CPMs and greater profitability.
• Platform Migration: The "platform of last resort" is determined by the effectiveness of bot removal, with the worst performers attracting more bot traffic.

4. Sourced Traffic is a Major Risk

• Higher Bot Rates: Sourced traffic had more than three times the bot percentage compared to unsourced traffic.
• Improvement Over 2014: While sourced traffic still posed a significant risk, it showed a slight improvement compared to 2014, where it was over four times more likely to contain bots.

5. Programmatic Ads are More Vulnerable

• Higher Bot Rates in Programmatic: Programmatic video had 73% more bots than the study average, while programmatic display had 14% more.
• Ineffective Prevention Methods: List-based bot prevention solutions were not effective in reducing bot fraud, as they failed to distinguish between human and bot traffic.

6. Bot Operators Hide Traffic Among Humans

• Complex Bots Mimic Humans: Sophisticated bots can mimic human browsing behavior, making them harder to detect.
• Residential IPs Dominant: Two-thirds of all sophisticated bot traffic originated from residential IP addresses, which complicates blacklisting efforts.
• Dynamic Nature of Bots: Bot traffic is a moving target, with the most recent infections posing the greatest risk due to their lack of detection.

Key Recommendations

1. Action Plan for All Stakeholders

• Implement Combined Defenses: Use anti-fraud technologies, proactive policies, and strategies to effectively combat bot fraud.
• Maintain Transparency: Ensure all stakeholders have access to transparency in media investments, especially for high-value segments like video.

2. Action Plan for Buyers

• Be Aware and Involved: Advertisers and agencies should be actively engaged in fraud prevention.
• Request Transparency: Demand transparency for sourced traffic and include anti-fraud language in contracts.
• Use Third-Party Monitoring: Employ third-party tools to ensure compliance with anti-fraud policies.
• Support Trustworthy Accountability Group (TAG): Align with industry groups that promote accountability and transparency.

3. Action Plan for Publishers, Platforms, and Exchanges

• Monitor Inventory: Continuously monitor for fraud and cut off sources that supply bots.
• Improve Measurement Policies: Ensure transparency and accurate measurement to prevent fraud.
• Avoid Partnering with Bot Sources: Do not partner with companies that source bot traffic.

Conclusion

The report underscores that bot fraud is a systemic and evolving threat in digital advertising. It emphasizes that no single solution can effectively address the issue, and that a coordinated, multi-layered approach is necessary to reduce fraud exposure and financial impact. Advertisers, publishers, and platforms must work together to implement robust detection and prevention mechanisms, ensuring the integrity of the digital advertising ecosystem.
