HTTP狀態(tài)碼是由Web服務(wù)器在響應(yīng)客戶端請(qǐng)求時(shí)返回的狀態(tài)標(biāo)識(shí)。它們用于表示服務(wù)器處理請(qǐng)求的結(jié)果，并提供了關(guān)于請(qǐng)求狀態(tài)的信息。 HTTP狀態(tài)碼對(duì)于SEO（搜索引擎優(yōu)化）很重要，原因如下： 1. 200狀態(tài)碼：表示成功返回請(qǐng)求。對(duì)于搜索引擎爬蟲(chóng)來(lái)說(shuō)，收到200狀態(tài)碼意味著頁(yè)面能夠正常訪問(wèn)，這能夠?qū)W(wǎng)站的排名產(chǎn)生積極的影響。 2. 301和302狀態(tài)碼：301狀態(tài)碼表示永久重定向，即已移動(dòng)的內(nèi)容已永久轉(zhuǎn)移到新位置，而302狀態(tài)碼表示臨時(shí)重定向，即內(nèi)容暫時(shí)在其他位置。這兩種狀態(tài)碼可以幫助搜索引擎正確索引網(wǎng)站的內(nèi)容，避免重復(fù)內(nèi)容的被視為不同網(wǎng)址。 3. 404狀態(tài)碼：表示請(qǐng)求的資源不存在。當(dāng)搜索引擎爬蟲(chóng)找不到所請(qǐng)求的頁(yè)面時(shí)，會(huì)得到404狀態(tài)碼。如果網(wǎng)站上存在較多的404頁(yè)面，則這可能會(huì)對(duì)SEO產(chǎn)生負(fù)面影響，因此應(yīng)盡量減少404頁(yè)面的出現(xiàn)。 4. 500和503狀態(tài)碼：500狀態(tài)碼表示服務(wù)器內(nèi)部錯(cuò)誤，503狀態(tài)碼表示服務(wù)器暫時(shí)無(wú)法處理請(qǐng)求。這兩種狀態(tài)碼對(duì)搜索引擎來(lái)說(shuō)都表示網(wǎng)站無(wú)法訪問(wèn)或者訪問(wèn)困難，可能會(huì)導(dǎo)致搜索引擎排名下降。綜上所述，了解HTTP狀態(tài)碼并正確處理它們對(duì)于SEO非常重要，可以幫助搜索引擎正確地理解和索引網(wǎng)站內(nèi)容，從而提高網(wǎng)站在搜索結(jié)果中的排名。

最近，本人負(fù)責(zé)的其中一個(gè)站點(diǎn)收錄出現(xiàn)了異常，趁著周末有空講述一下整個(gè)診斷過(guò)程。核心問(wèn)題有兩點(diǎn)，服務(wù)器架構(gòu)和網(wǎng)站程序架構(gòu)導(dǎo)致的;本篇僅分享服務(wù)器架構(gòu)導(dǎo)致的收錄異常。首先，介紹一下自己。本人就職于深圳某企業(yè)，長(zhǎng)期混跡于乙方外包公司，眾所周知seo外包公司接的是絕大部分是小企業(yè)網(wǎng)站，這些網(wǎng)站做的關(guān)鍵詞往往也僅是改個(gè)TDK就完成排名的工作。再加上，目前絕大部分中小站點(diǎn)的架構(gòu)很簡(jiǎn)單，開(kāi)源CMS+單一云服務(wù)器

Google和百度對(duì)搜索引擎習(xí)慣的分析

本文介紹Google和百度兩大搜索引擎的網(wǎng)頁(yè)收錄習(xí)慣、網(wǎng)頁(yè)排名習(xí)慣等，幫助站長(zhǎng)合理優(yōu)化自己的網(wǎng)頁(yè)，達(dá)到Google百度兩面笑的目的。Google搜索引擎習(xí)慣Google作為全球最大的多語(yǔ)言搜索引擎在發(fā)展歷史過(guò)程中形成了自己的網(wǎng)頁(yè)收錄習(xí)慣，也建立起自己的一套標(biāo)準(zhǔn)。研究Goolge收錄網(wǎng)頁(yè)的習(xí)慣有利于更好迎合Google搜索引擎的口味，達(dá)到提高網(wǎng)頁(yè)收錄量和收錄排名的目的。我們暫且不研究Google對(duì)其

爬蟲(chóng)抓取診斷403什么意思？

當(dāng)爬蟲(chóng)程序請(qǐng)求服務(wù)器時(shí)，如果服務(wù)器返回403錯(cuò)誤碼，則意味著服務(wù)器正確地接收了請(qǐng)求，但由于某些原因，服務(wù)器禁止該請(qǐng)求的訪問(wèn)。這通常表示訪問(wèn)被拒絕，可能是由于HTTP請(qǐng)求頭或身份驗(yàn)證方面的問(wèn)題。服務(wù)器可能會(huì)要求用戶進(jìn)行身份驗(yàn)證或者限制用戶的訪問(wèn)權(quán)限。建議重新檢查請(qǐng)求頭和身份驗(yàn)證，以確保請(qǐng)求被正確發(fā)送并且可以被服務(wù)器接受。

通過(guò)HTTP狀態(tài)代碼看搜索引擎怎么Crawl你的站

威海Spider 威海HTTP狀況碼

點(diǎn) HTTP狀態(tài)代碼是指網(wǎng)站服務(wù)器對(duì)用戶請(qǐng)求的響應(yīng)結(jié)果。根據(jù)不同的HTTP狀態(tài)代碼，搜索引擎可以了解網(wǎng)頁(yè)更新的頻率，以及網(wǎng)頁(yè)存在的情況，從而判斷是否應(yīng)該繼續(xù)Crawl你的站點(diǎn)： HTTP 200：這是最常見(jiàn)的狀態(tài)碼，表示請(qǐng)求成功。搜索引擎會(huì)解析服務(wù)器返回的網(wǎng)頁(yè)內(nèi)容，并繼續(xù)向您的站點(diǎn)爬取其他頁(yè)面。 HTTP 301/302：這些狀態(tài)碼表示鏈接已經(jīng)更改，搜索引擎會(huì)更新當(dāng)前網(wǎng)頁(yè)的鏈接，并繼續(xù)爬取新
