WARC Media's latest Platform Insights report shows YouTube's ad revenue growth decelerating from 14.7% in 2024 to 11.7% in 2025, with a forecast of 7.9% by 2027, putting TikTok on track to overtake it in 2028. Fospha data cited in the report suggests that last-click attribution underreports YouTube's revenue contribution by 15.9x.
Why it matters for advertisers
For you, this means YouTube's problem may be measurement as much as demand, so revisit how you credit it before shifting budget on last-click numbers.
