HTTP狀態(tài)碼301與302有什么區(qū)別

301和302都是HTTP重定向狀態(tài)碼的一種，它們的區(qū)別在于重定向的方式不同。 301狀態(tài)碼表示永久性重定向，告訴瀏覽器被請求的資源已經(jīng)被永久性地移動(dòng)到了新的位置并且搜索引擎應(yīng)該更新他們的索引。瀏覽器會(huì)記住這個(gè)重定向，并且在以后的請求中直接訪問新的資源地址。這種方式適用于網(wǎng)站URL結(jié)構(gòu)做出的永久性更改或者將網(wǎng)站遷移至新的域名。 302狀態(tài)碼表示臨時(shí)性重定向，告訴瀏覽器被請求的資源暫時(shí)性地被移動(dòng)到了新的位置。瀏覽器會(huì)記住這個(gè)重定向，但是在以后的請求中會(huì)再次訪問舊的資源地址，因?yàn)檫@個(gè)重定向只是臨時(shí)性的。這種方式適用于網(wǎng)站維護(hù)或者某個(gè)資源只暫時(shí)性地移動(dòng)到了其他地址。總的來說，301狀態(tài)碼適用于永久性更改，302狀態(tài)碼適用于臨時(shí)性更改。

網(wǎng)站被降權(quán)的十大處理方式

一、檢查引起降權(quán)的原因 1.檢查網(wǎng)站的內(nèi)容，看看是否存在大量的重復(fù)的內(nèi)容、關(guān)鍵字過度優(yōu)化垃圾連接以及常見的SEO 術(shù)語； 2.檢查網(wǎng)站的內(nèi)部鏈接結(jié)構(gòu)，是否存在大量外鏈或過多的環(huán)形鏈接； 3.檢查網(wǎng)站是否發(fā)生惡意傳播，惡意收費(fèi)或在一些網(wǎng)站上進(jìn)行關(guān)聯(lián)性連接等； 4.檢查垃圾外鏈以及其他惡意逃避技術(shù)； 5.檢查搜索引擎蜘蛛的抓取狀況； 6.檢查站內(nèi)網(wǎng)頁URL是否重復(fù)； 7.檢查Web服

網(wǎng)站域名的詳解，域名和網(wǎng)站名的聯(lián)系

威海seo專題威海域名與seo
2302

域名是什么以SEOWHY舉例：www.seowhy.com。域名是seowhy.com；www是seowhy.com下面的一個(gè)子域名。但人們的習(xí)慣是認(rèn)為，帶www和不帶www指向同一個(gè)網(wǎng)站。很多用戶輸入域名時(shí)喜歡不帶www，比如taobao.com，所以，不帶www的域名要記得解析到網(wǎng)站IP。喜歡輸入帶www的用戶，可能會(huì)把3個(gè)w，輸入為2或4個(gè)。所以，ww.seowhy.com和wwww.seo

HTTP狀態(tài)碼301與302有什么區(qū)別

HTTP狀態(tài)碼301和302都是重定向狀態(tài)碼，用來告訴客戶端需要訪問一個(gè)新的URL。它們的區(qū)別在于： 1. 狀態(tài)碼301表示永久重定向，即原始URL永久地不可用，所有訪問該URL的請求都將被重定向到新的URL上。而狀態(tài)碼302表示臨時(shí)重定向，即原始URL只是暫時(shí)不可用，請求將被重定向到一個(gè)臨時(shí)URL上，之后可能會(huì)再次返回原始URL。 2. 由于301表示永久重定向，搜索引擎會(huì)將原始URL的權(quán)重

HTTP狀態(tài)碼301與302有什么區(qū)別

301：（永久移動(dòng)）請求的網(wǎng)頁已被永久移動(dòng)到新位置。服務(wù)器返回此響應(yīng)（作為對GET或HEAD請求的響應(yīng)）時(shí)，會(huì)自動(dòng)將請求者轉(zhuǎn)到新位置。302：（臨時(shí)移動(dòng)）服務(wù)器目前正從不同位置的網(wǎng)頁響應(yīng)請求，但請求者應(yīng)繼續(xù)使用原有位置來進(jìn)行以后的請求。此代碼與響應(yīng)GET和HEAD請求的301代碼類似，會(huì)自動(dòng)將請求者轉(zhuǎn)到不同的位置。HTTP狀態(tài)碼301與302的區(qū)別：1、它們之間關(guān)鍵區(qū)別在，資源是否存在有效性；2、
