    # AI驅動已久的的數位廣告生態圈 — DSP、DMP、SSP到底是什麼? Google在2023年五月的行銷大會上秀出了新趨勢,但其實數位廣告生態圈早擁有以下百花齊放的平台,去幫助廣告主(advertiser)以及發布商(publisher)進行一連串的廣告交易行為。 我們可以將競價過程想像為經濟學的供給面與需求面,從需求面的廣告主(advertiser)、廣告需求方平台,交易中介所的廣告交易平台,以及供給方的廣告供應方平台、發布商,以下將介紹各個角色 ![](https://hackmd.io/_uploads/Syt5GDoBn.jpg) ### 需求方 1. 廣告業主(Advertiser):為有意購買廣告版位的買方,像是品牌主、為求曝光的媒體及追求App下載量的發行商等,計畫在各平台上刊登、投放自家廣告以爭取曝光機會。 2. 廣告需求方平台(Demand-Side Platform,DSP):為一個程序化的廣告平台,採用OpenRTB (Real-Time Bidding)的技術,讓這些廣告業主、媒體可以自動競價及購買發布平台上的各種廣告版位,像是現觀科技的MI-DSP™、The Trade Desk。 寫到這裡就得提起是如何透過AI驅動的了,如果以上交易都是每筆手動填單,想必相當累人,為了達到即時、最佳化且自動化的交易,程序化購買(Programmatic Buying)這樣的技術便油然而生。 程序化購買是以流量的觀點進行廣告買賣,以IAB規定為例200毫秒(ms)內都有數百萬個交易請求(bid request),因此供給方須提供請求方的http位置,且交易結構符合美國廣告協會IAB的Open RTB規範。 你在任何裝置上所看見的廣告,都是經過瀏覽器渲染後發送給聯播網(Ad Network),而模型也會根據聯播網服務的成效不斷修正出價模式、行為等。 而廣告主也一定希望能夠讓自己的目標受眾看見廣告,因此通常也會使用數據管理平台管理平台(Data Management Platform),可結合第一方、第二方、第三方資料,進一步分析使用者的行為數據,找到最合適的目標受眾進行廣告投放,如現觀科技的MI-DMP™在印尼市場便是結合了Indosat Ooredoo的第一方資料源,提供印尼市場上的廣告主合適的受眾區隔。 3. 廣告交易平台(Ad Exchange):為一個媒合買方(DSP)與賣方(SSP)交易的仲介拍賣平台,像是知名的Google Ad Manager、Smaato、Yahoo Exchange等。 ### 供給方 4. 廣告供應方平台(Supply-Side Platform,SSP): 為一個技術平台,能讓發布平台、媒體擁有者管理和協調廣告庫存,並協助其能自動出售數位廣告。即廣告供應方平台會託管各方發布平台及媒體的廣告版位,以有效率且極大化利潤的方式協助賣方出售廣告版位,幫助擁有的流量變現。 5. 發布商(Publisher):為擁有廣告版位的供給方,像是新聞媒體、Youtube、Google、優質部落格網站等。 ### 美國廣告協會IAB 看完以上,也順便跟大家介紹IAB Tech Lab這個國際廣告行業權威技術標準組織,設立宗旨為促進整體數位廣告產業的成長,負責為線上廣告制定國際標準並提供法律支持,當中包括廣告主、廣告代理商、廣告技術提供商、媒體公司、數據公司等,成員如 Google、Facebook、Amazon 等國際公司。 ### 即時競價OpenRTB 是一種銷售媒體的方式,讓單一廣告曝光可以透過統一的通訊協定進行即時競價,目前OpenRTB的最新版本已發布至 [OpenRTB v2.6](https://iabtechlab.com/standards/openrtb/?__hstc=230754752.494ece988f5110bcd7b81a6a281a1912.1685072188460.1685072188460.1685083534588.2&__hssc=230754752.1.1685083534588&__hsfp=226124057#related),點擊左方連結了解更多。 參與庫存(inventory)拍賣的各家DSP會在同一時間收到impression並決定是否出價,版位由出價最高者標得,如同前述由IAB制定的OpenRTB規範便制定了各家DSP須在200ms內完成競價拍賣。 ###### tags: `Technical Sharing`
