Comscore has begun tracking sponsored links inside ChatGPT responses using opt-in user-panel data rather than synthetic test prompts, per PPC Land. In its first tracked category, hotel-related prompts carrying a sponsored link rose from 6% in March 2026 to 14% in April and 24% in May — a fourfold increase in three months. Comscore's Chief Technology and Analytics Officer, Smriti Sharma, said the company is extending its "trusted, independent measurement" to AI platforms; the company did not disclose panel size or composition.

Why it matters: A third-party measurement firm building a standing panel for paid AI-chat placements means advertisers will soon have independent verification of ChatGPT ad performance, not just platform-reported figures.
