出價模擬
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
您可以運用出價模擬功能，估算不同出價情境下廣告群組、條件和廣告活動的成效。您可以根據這項資訊調整及最佳化出價策略。
Google Ads API 的出價模擬功能可預測以各種方式變更出價後，對費用、曝光次數和點擊次數的影響。這與 Google Ads 使用者介面中的出價模擬工具類似，且是以歷來資料為依據。如要瞭解前瞻預測，請參閱關鍵字規劃的類似概念。
用途
假設您放送廣告幾週後，發現費用遠超出預期或想支出的金額。
您想測試稍微降低出價會發生什麼情況。廣告的瀏覽和點擊次數會減少多少？這樣會便宜多少？
反之，如果廣告獲得的曝光和點擊次數不如預期，如何判斷出價應設為多少，才能解決這個問題？
出價模擬工具可協助您研究這些情境。擷取出價模擬資料時，系統會顯示廣告放送期間的預估觀看次數、點擊次數和費用。
出價模擬工具可讓您查看目前出價層級下過去一週的成效統計資料，以及使用不同出價金額時，同一時間範圍內的模擬成效。
分析廣告過去的成效差異，有助於您做出更明智的決策，瞭解日後該如何調整出價和廣告活動層級出價修飾符。

You can use this information to\nadjust and optimize your bidding strategy.\n\nThe bid simulations of Google Ads API predict how changing your bid in\nvarious ways impacts cost, impressions, and clicks. This is analogous to\n[bid simulators](//support.google.com/google-ads/answer/2470105) in the\nGoogle Ads UI and is based on historical data. For forward-looking predictions,\nrefer to the similar concept of\n[keyword planning](/google-ads/api/docs/keyword-planning/overview).\n\nUse case\n--------\n\nSuppose you have an ad that's been running for a few weeks, and it is costing\na lot more than you expected or wanted to spend.\n\nYou want to test what might happen if you lower your bids a little. How many\nfewer views and clicks would your ad get? How much less would it cost?\n\nConversely, what if your ad isn't getting the number of impressions and clicks\nyou expect? How do you know where you should set your bids to fix that\nproblem?\n\nBid simulations help you research these scenarios. When you fetch a bid\nsimulation, it shows projected views, clicks, and cost during the time period\nyour ad was showing.\n\nWith bid simulations, you can examine performance statistics for the past week\nat the current level of bidding, alongside simulated performance over the same\ntime period using different bid amounts.\n\nBy analyzing how your ads might have performed differently in the past, you can\nmake more informed decisions about how to adjust your bids and campaign-level\nbid modifiers for the future."]]
