Python：腳本為您的利基搜索關鍵字提供Google Autosuggest趨勢摘要

每個人都喜歡Google趨勢，但是長尾關鍵字有點棘手。 我們都喜歡官方 谷歌趨勢服務 以獲得有關搜索行為的見解。 但是，有兩點阻礙了許多人將其用於堅實的工作。

1. 當您需要尋找時 新的利基關鍵字， 那裡 Google趨勢中的數據不足 
2. 缺少用於向Google趨勢發出請求的官方API：當我們使用諸如 趨勢，那麼我們必須使用代理服務器，否則我們將被阻止。 

在本文中，我將分享我們編寫的Python腳本，該腳本可通過Google Autosuggest導出趨勢關鍵字。

隨著時間的推移獲取並存儲自動建議的結果 

假設我們有1,000個Seed關鍵字要發送到Google Autosuggest。 作為回報，我們可能會得到大約200,000萬 長尾巴 關鍵字。 然後，我們需要在一周後執行相同的操作，然後比較這些數據集來回答兩個問題：

• 哪些查詢是 新關鍵字 與上次相比？ 這可能是我們需要的情況。 Google認為這些查詢變得越來越重要-通過這樣做，我們可以創建自己的Google Autosuggest解決方案！ 
• 哪些查詢是 關鍵字不再 趨勢？

該腳本非常簡單，我共享的大多數代碼 這裡。 更新後的代碼將保存過去運行的數據，並隨時間比較建議。 為了簡化起見，我們避免使用基於文件的數據庫（如SQLite）–因此，所有數據存儲都在下面使用CSV文件。 這使您可以在Excel中導入文件並探索適合您業務的利基關鍵字趨勢。

利用此Python腳本

1. 輸入應發送到自動完成功能的種子關鍵字集：keyword.csv
2. 根據需要調整腳本設置：
   • 語言：默認為“ en”
   • 國家/地區：默認為“我們”
3. 安排腳本每週運行一次。 您也可以根據需要手動運行它。
4. 使用keyword_suggestions.csv進行進一步分析：
   • 初見：這是查詢在自動建議中首次出現的日期
   • 最後一次露面：最後一次查詢的日期
   • 是新的：如果first_seen == last_seen我們將其設置為 真 –只需過濾此值即可在Google自動建議中獲得新的趨勢搜索。
