This impact was compounded by the ongoing macroeconomic effects of the global pandemic with our advertising partners facing a variety of supply chain interruptions and labor shortages. This in turn reduces their short-term appetite to generate additional customer demand through advertising at a time when their businesses are already supply constrained.
In addition, we are hearing from advertising partners across a wide variety of industries that they are facing disruptions in their supply chains as well as labor shortages. Unfortunately, these changes are occurring during the season when our advertising partners would normally expect their supply chains to be operating at peak capacity and other time when we would otherwise expect peak advertising demand to drive contestation and therefore peak prices in our auction. While it is difficult to predict the duration and magnitude of these macroeconomic factors on the businesses of our partners, we have assumed that these headwinds will persist throughout Q4. When combined with the measurement related headwinds we are seeing in our direct response business, we expect a compounding impact on the level of contestation and pricing in our auction-based ecosystem, relative to what we would otherwise expect during the second half of Q4 in particular.
雖然看起來還是有四成左右比例來自移動端,但CEO Jeff Green在2020Q3的財報電話會議中,提過只有大約10%是與蘋果IDFA相關,並會控制在10%以內。在2021Q1財報電話會議中,Jeff Green重申蘋果IDFA的變化對其業務基本上沒甚麼影響。
In fact, to our business as it relates to the IDFA changes, we have seen no material change in spend as a result of the IDFA changes. And that's in part because of what I was saying before, which is we have the ability to look at 12 million ads per second.
Jeff Green提到每秒1,200萬個廣告的意思是,假設1,200萬個廣告庫存當中有100萬個與蘋果IDFA相關,而這些地方效果不好,TTD的平台會幫助客戶在其他1,100萬個廣告組合中尋找更適合的地方投放廣告,因此可以將蘋果IDFA的衝擊降到最低。
