The ad‑verification firm Pixalate has published its fourth‑quarter 2025 benchmark study on invalid traffic (IVT) and ad fraud across three key Asia‑Pacific markets: Japan, Singapore and India. The data‑driven analysis, which also forms part of a broader set of regional reports covering North America and Europe, focuses on programmatic advertising delivered through desktop and mobile web, mobile applications and Connected TV (CTV).
Scope of the benchmark
The report concentrates on programmatic impressions that pass through open‑auction channels on the buy side. By examining more than 103 billion impressions recorded in Q4 2025, Pixalate’s data‑science team aimed to capture a representative slice of the digital ad ecosystem in the three APAC economies. The study isolates IVT – traffic that fails to meet basic quality or completeness criteria – and distinguishes it from more malicious “ad fraud” as defined by the Media Rating Council (MRC).
Core findings
- CTV leads the IVT curve – 40 % of CTV impressions were classified as invalid in Japan and Singapore; data for India were not available.
- Mobile apps trail closely – Invalid traffic rates reached 36 % in Japan, 43 % in Singapore and 29 % in India.
- Desktop and mobile web performed better – The share of IVT was 16 % in Japan, 21 % in Singapore and 17 % in India.
- Global averages for comparison – Across the broader dataset, web traffic exhibited a 23 % IVT rate, mobile‑app traffic 36 %, and CTV 21 %.
These numbers suggest that CTV, still a relatively nascent channel in the region, is currently the most vulnerable to low‑quality impressions, while mobile‑app environments also face pronounced challenges.
Why the numbers matter
For advertisers allocating budget across APAC, the elevated IVT percentages signal a need for tighter verification controls, especially when purchasing inventory on CTV platforms. Brands that rely on programmatic buying to reach premium audiences risk inflated media costs and compromised campaign performance if a substantial share of impressions never reaches a real viewer. Publishers, on the other hand, may see revenue erosion if advertisers demand higher discounts or shift spend toward vetted, low‑risk channels.
The disparity between device categories also hints at differing levels of ecosystem maturity. Desktop and mobile‑web markets, with longer histories of ad‑tech standards and third‑party verification, appear to have mitigated many of the low‑quality traffic sources that still plague newer formats like CTV.
Methodology at a glance
- Pixalate’s analysis draws exclusively from buy‑side open‑auction traffic, deliberately excluding private‑market deals that often involve different verification layers.
- The dataset spans over 103 billion programmatic impressions recorded during the October‑December 2025 window, offering a statistically robust foundation for the regional breakdowns.
- The company applied its proprietary detection engine, which is accredited by the MRC for identifying “Sophisticated Invalid Traffic” (SIVT). The engine evaluates a range of signals – including IP reputation, device fingerprinting, and behavioral anomalies – to flag impressions that do not meet the council’s definition of valid ad traffic.
Access to the full reports
Pixalate has made the complete set of Q4 2025 benchmark PDFs available for download. Stakeholders can retrieve country‑specific reports for Japan, Singapore, India, the United States, Canada, the United Kingdom, Germany, Mexico, and a consolidated global overview. The files provide deeper granularity, such as hourly IVT trends, fraud‑type breakdowns, and recommendations for mitigation.
Industry context and regulatory backdrop
Invalid traffic remains a persistent pain point for the digital advertising supply chain. According to the MRC, IVT encompasses any impression that fails to satisfy basic quality standards – for example, non‑human bots or traffic generated by scripts designed to inflate view counts. When such traffic is deliberately engineered to deceive advertisers, it crosses the threshold into “ad fraud.”
Regulators across the APAC region have begun to tighten oversight on data privacy and ad‑tech practices, with several jurisdictions adopting stricter consent frameworks and requiring greater transparency from vendors. While Pixalate’s benchmarks do not constitute regulatory findings, they provide a data‑driven barometer that can inform compliance strategies and help advertisers align with emerging standards.

Implications for programmatic buyers
The report’s findings reinforce the importance of integrating verification tools directly into demand‑side platforms (DSPs) and supply‑side platforms (SSPs). By filtering out suspect impressions before they enter the bidding process, buyers can preserve budget efficiency and protect brand safety.
Moreover, the stark contrast between CTV and web‑based channels suggests that advertisers should consider a tiered approach: allocate a larger share of spend to inventory sources with proven low‑IVT rates, while employing rigorous post‑impression audits for emerging formats.
Publisher considerations
Publishers operating CTV apps or delivering video inventory through over‑the‑top (OTT) services may need to invest in server‑side ad insertion (SSAI) solutions that embed verification at the point of delivery. Such measures can reduce the exposure to fraudulent traffic and improve the perceived quality of their inventory, potentially unlocking higher CPMs.
For mobile‑app developers, adopting in‑app fraud detection SDKs and partnering with accredited verification providers can mitigate the 29‑43 % IVT rates observed in the benchmark.
