TF-IDF分詞加權算法是一種文本處理技術，是根據(jù)文檔的大小，詞頻和文檔的頻率來給詞語加權。對文本內(nèi)容的理解和分析有很大幫助，所以是有用的。

百度知道、百度文庫頻頻出現(xiàn)在搜索結果里，這是什么節(jié)奏

威海seo問答威海seo

百度知道和百度文庫是百度旗下的兩個服務平臺。百度知道是一個問答平臺，用戶可以在這里提出問題并獲得其他用戶的回答。它通常會出現(xiàn)在搜索結果中，因為Google傾向于顯示與搜索關鍵字有關的相關內(nèi)容。如果問題的答案在百度知道上被廣泛討論或者被認為是最相關的答案，那么百度知道的結果很可能會出現(xiàn)在搜索結果中。百度文庫是一個在線文檔分享平臺，用戶可以在這里分享和下載各種文檔，如學術論文、調(diào)研報告、教學材

網(wǎng)站首頁排名比內(nèi)頁排名要低

這個說法不一定準確。網(wǎng)站首頁和內(nèi)頁在搜索引擎排名方面并沒有明顯的區(qū)別。實際上，許多內(nèi)頁在搜索引擎中排名很靠前，而首頁可能需要更長時間的搜索引擎優(yōu)化才能獲得較高的排名。首頁通常是網(wǎng)站的重要門戶，包含關鍵信息，可能會獲得更多的內(nèi)部和外部鏈接，這可以幫助其在搜索引擎中獲得更好的排名。然而，如果內(nèi)頁的內(nèi)容質(zhì)量更高或更受歡迎，那么內(nèi)頁的排名可能會超過首頁。因此，網(wǎng)站主人應該為所有頁面進行搜索引擎優(yōu)化

網(wǎng)站啟用CDN，百度收錄時間顯示為1天前

，是什么原因引起的？ CDN的出現(xiàn)會使網(wǎng)站的資源，如靜態(tài)文件及部分HTML文件，請求多分散到全球各地的CDN節(jié)點上，這樣在你刷新頁面時，訪問的數(shù)據(jù)速度也會更快，而資源被譽收錄的時間也只是前一天而已，所以百度收錄時間顯示為1天前，是正常的。

網(wǎng)站欄目規(guī)劃該怎么做？

用真的提問于 3年之前在zac老師您的qa頁面發(fā)現(xiàn)你在想問下新站如何優(yōu)化，哪些項目是一定要注意的點回答中說要注意幾點，其中就包括網(wǎng)站結構優(yōu)化和欄目規(guī)劃等。我對于欄目規(guī)劃不是很懂，應該說就是不懂。我有看zac老師的《實戰(zhàn)代碼3》這本書，但是在我的印象力好像沒有看到關于欄目規(guī)劃這方面的希望zac老師能夠簡潔明了的說一下。因為自己比較笨，希望老師能夠說的像大白話那種一樣通俗易懂。萬
