Maf 提問于 3年之前

我在GA的移除網(wǎng)址欄目提交了原先的404頁面，并且也刪除了網(wǎng)站后臺的頁面，但現(xiàn)在又在網(wǎng)站日志中發(fā)現(xiàn)google蜘蛛來爬這些頁面，這是為什么？是否會在熬成不好的影響？

Zac 管理員回答于 3年之前

首先，先檢查一下被刪除的頁面是否正常返回404錯誤，而不是其它服務器頭信息?？吹巾撁娌淮嬖谥惖腻e誤，不一定服務器頭信息就是404。

對404頁面，搜索引擎通常還會來抓一陣，不會一看到404，馬上刪除頁面，目的是防止站長誤操作。過一段時間，總是404，搜索引擎才確認頁面確實刪除了，才從索引庫刪除，也不再抓取。所以等著就行了。

通常404錯誤不會造成不好影響，畢竟刪除頁面、下架產(chǎn)品都是很正常的事。除非404數(shù)量巨大，搜索引擎可能會疑惑，網(wǎng)站發(fā)生了什么問題？

嗯嗯，謝謝指教

百度快照停滯不更新了是什么原因

作為語言人工智能模型，我無法確定具體原因，但可能是由于以下原因之一： 1.網(wǎng)站內(nèi)容沒有更新。如果您的網(wǎng)站內(nèi)容不經(jīng)常更新，百度爬蟲將無法找到新的內(nèi)容，并且不會更新快照。 2.網(wǎng)站的技術問題。如果您的網(wǎng)站存在技術問題，例如服務器響應時間太長，緩存設置不正確等，這可能會導致百度爬蟲無法訪問您的網(wǎng)站，并且無法更新快照。 3.百度爬蟲的更新頻率有所下降。百度爬蟲可能會對一些網(wǎng)站的更新頻率進行動態(tài)調整，

學習SEO需要先學會做網(wǎng)站嗎？

李堅華提問于 3年之前您好，Zac前輩，我作為一個剛進入SEO的新人，學習SEO需要先學會做網(wǎng)站嗎？我通看了一遍你的作品《SEO實戰(zhàn)密碼》，我沒有網(wǎng)站方面的基礎，基本不了解和熟悉HTML以及CSS的原理以及能看懂并做出簡單修改，書上你提到的不少地方，比如404，301，NOfollow這些，似乎都是跟代碼有關的。要深入學習SEO，需要學會做網(wǎng)站嗎？需要先學會做網(wǎng)站的話，麻煩您推薦一兩本跟SEO

https改造后排名掉了

https更安全，搜索引擎更傾向于更安全的站點，所以如果網(wǎng)站改造成https后，搜索引擎可能會給排名上一定的影響，但具體影響程度未知，也可能不存在明顯的影響。一般來說，網(wǎng)站改造為https后應該會有利于搜索引擎優(yōu)化，從而提升網(wǎng)站排名，但并不能保證一定會得到提升。

如果您想轉型并開啟新的職業(yè)生涯，以下是一些可能有用的步驟： 1. 定位自己的興趣和技能：您需要評估自己的技能和興趣，并確定您在未來的職業(yè)中想要從事哪些方面。如果您喜歡寫作，那么您可以嘗試成為一名自由撰稿人，或者更專業(yè)地成為一名特約編輯。如果您喜歡數(shù)據(jù)分析，則可以考慮成為一名數(shù)據(jù)分析師或數(shù)據(jù)科學家。 2. 學習新的技能：根據(jù)您想要從事的新職業(yè)，您可能需要學習新的技能或知識。您可以通過參加在線課程
