CPMs up 24% YoY while publisher traffic is softening - something's shifting in the auction layer
An analysis of over 35 billion impressions and $55 million in revenue reveals a notable shift in the advertising auction layer, with practitioners observing a 24.2% year-over-year increase in overall CPMs. This rise occurs despite a softening in publisher traffic, marked by declines in sessions per user and engagement rates, alongside slipping organic search. While ChatGPT referrals doubled month-over-month, they still constitute only 3.4% of total referral volume. Specific trends include desktop commanding a premium over mobile and video CPMs turning positive year-over-year, though CTV remains down by 14.7% year-over-year despite a monthly recovery.
