Mobile Ad Fraud Shifts to Affiliate Channels in Germany
AppsFlyer’s “State of Fraud for Marketers 2026” report shows that mobile ad fraud remains a material measurement risk in Germany even as overall detected fraud rates fell into early 2026. After peaking in mid‑2025, Android fraud in Germany declined to 10.5% and iOS to 8.7% by Q1 2026, but fraud patterns have shifted: affiliate channels in Germany saw an increase in detected fraud share (from 33.7% to 40.2%), organic installs now account for a large share of fraud globally (52%), and German iOS detections show a rising share of store‑validation fraud (66% → 81%). The findings are based on anonymized, aggregated data from 246,000 apps and 106.4 billion installs (55.3 billion paid installs) in the analysis window Q1 2025–Q1 2026.

OpenAI Enhances ChatGPT Ads with Image Formats and Measurement
OpenAI is expanding its ChatGPT advertising offering with a new visual ad format that uses image carousels, initially appearing during image generation. The ads are clearly labeled and separate from content, and the rollout begins in October 2026 for US users and select advertisers, with plans to reach over 60 markets. ChatGPT now surpasses 1.2 billion weekly users, making it the largest AI-based consumer platform. Early results show strong performance, such as WeightWatchers' 15.3% lower cost per acquisition and high new-visitor rates for brands like Dose and Portland Leather. However, a TrafficGuard study reveals that ad clicks are 3.6 times more likely to come from datacenters or proxies compared to Google Ads, with invalid click rates ranging from 0.1% to 34%, indicating early ad fraud challenges. Advertisers are encouraged to verify performance independently.
TikTok Attribution Source Optimization Aligns Measurement and Bidding
TikTok introduces Attribution Source Optimization for app advertisers, allowing them to select their preferred attribution source (e.g., MMP) to inform campaign optimization. This addresses discrepancies between platform and MMP reporting by aligning measurement and bidding signals. Features include support for Adjust, AppsFlyer, Singular, and upcoming integrations with Airbridge, Branch, Kochava, and Tenjin. Alpha testing with iOS gaming app That's My Seat showed an 18% lift in Day 0 tROAS and 15% increase in billing ratio. The move aims to give advertisers more control as AI-driven automation increases, ensuring optimization uses the same conversion signals marketers trust for performance evaluation.
OpenAI's Measurement Gaps Keep ChatGPT Ads Budgets at Test Level
Seven months after OpenAI introduced ads in ChatGPT, marketers still face measurement hurdles, as agencies like Accuracast report discrepancies—zero conversions despite form fills and 100 clicks vs. 20 tracked internally—along with 24-36 hour delays and a lack of demographic or prompt data. Legal concerns about OpenAI's terms and data use deter many from enabling conversion tracking, slowing custom audience adoption. Test budgets range from £10,000 to £30,000, with clients spending under $100,000 monthly on ChatGPT versus $10 million on Google. Third-party measurement through partners like AppsFlyer and Adjust is deemed essential, though limited. Meanwhile, DoorDash expands retail media by partnering with Macy's, Timberland, and others, the Trump administration spends millions on pro-Trump ads, Swap Commerce acquires Vizby, and OpenX hires John Rogers as SVP of Global Publisher Development. OpenAI declined to comment.
