運用 PPS 改善廣告活動
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
您可以在廣告請求中以發布商提供的信號 (PPS) 的形式傳送目標對象和比對內容資料。透過 PPS，您可以使用使用者資料，透過標準分類方式，向所有交易類型的出價方傳達目標對象特徵，藉此改善程式輔助營利，而無須分享使用者 ID。目標對象特徵可包含行為和興趣相關資料 (IAB 目標對象分類 1.1)，以及比對內容資料 (IAB 內容分類 2.2)。您也可以傳送發布商提供的結構化信號，這些信號由 Google 定義，並允許傳送額外信號。
建構使用者信號 JSON
在頂層建立含有單一鍵/值組合的 JSON 物件。鍵應為 PublisherProvidedTaxonomySignals，其值應為物件的陣列。陣列中的每個物件都應包含 2 個鍵/值組合：
建構結構化信號陣列
針對結構化信號，請新增包含物件陣列值的 PublisherProvidedStructuredSignals 鍵。根據下列信號鍵/值清單建構物件：

請參閱以下範例，如何使用 IAB_AUDIENCE_1_1 和 IAB_CONTENT_2_2 當做分類信號，並包含結構化信號。
const userSignals = {
"PublisherProvidedTaxonomySignals": [{
"taxonomy": "IAB_AUDIENCE_1_1",
"values": ["6", "284"]
// '6' = 'Demographic | Age Range | 30-34'
// '284' = 'Interest | Business and Finance | Mergers and Acquisitions'
},
{
"taxonomy": "IAB_CONTENT_2_2",
"values": ["49", "138"]
// '49' = 'Books and Literature | Poetry'
// '138' = 'Education | College Education | College Planning'
}],
"PublisherProvidedStructuredSignals": [{
"type": "audio_feed",
"single_value": "af_1",
},
{
"type": "delivery",
"values": ["cd_1", "cd_3"],
},
],
};
請按照下列步驟使用 IMAStreamRequest 傳送 PPS：
let userSignals = """
{
"PublisherProvidedTaxonomySignals": [
{
"taxonomy": "IAB_AUDIENCE_1_1",
"values": [
"1",
"284"
]
}
],
}
"""
let base64Signals = Data(userSignals.utf8).base64EncodedString()
var encodedSignals = base64Signals.replacingOccurrences(of: "+", with: "%2B")
encodedSignals = encodedSignals.replacingOccurrences(of: "/", with: "%2F")
encodedSignals = encodedSignals.replacingOccurrences(of: "=", with: "%3D")
streamRequest.adTagParameters = { "ppsj" : encodedSignals}
