301重定向怎么進(jìn)行URL標(biāo)準(zhǔn)化設(shè)置？

經(jīng)常會(huì)碰到這樣的情況，其他網(wǎng)站鏈接你的站點(diǎn)時(shí)，會(huì)用下面的鏈接：

www.example.com

example.com/

www.example.com/index.html

example.com/index.php

而這樣導(dǎo)致：你站點(diǎn)主域名的PR值分散到其他幾個(gè)URL上。

如果你用301重定向把其他三個(gè)URL轉(zhuǎn)到

www.example.com

PR也就集中在主域名：www.example.com 了。

301重定向怎么進(jìn)行URL標(biāo)準(zhǔn)化設(shè)置？

設(shè)置.htaccess文件（只適用于linux系統(tǒng)，并需要虛擬主機(jī)支持。）

使訪問example.com/的時(shí)候就會(huì)自動(dòng)轉(zhuǎn)到www.example.com

在.htaccess文件里寫上以下代碼即可。

RewriteEngine on

RewriteCond %{http_host} ^mydomain.com [NC]

RewriteRule ^(.*)$ http://www.mydomain.com/$1 [L,R=301]

來(lái)源：搜外網(wǎng)

sitemap提交后，多久能被百度抓取？

通常情況下，sitemap提交后，百度會(huì)在1-2天內(nèi)進(jìn)行抓取。但具體時(shí)間也受到網(wǎng)站規(guī)模、更新頻率、抓取限制等因素的影響。如果長(zhǎng)期未被抓取，可以檢查一下sitemap是否存在問題，并通過(guò)百度站長(zhǎng)平臺(tái)的工具進(jìn)行排查。

1：虛擬空間設(shè)置方法現(xiàn)在的idc提供商基本都提供404設(shè)置的功能，直接上傳文件設(shè)置即可。每個(gè)空間商的控制面板都不同，我在這里就不多說(shuō)了。2：IIS下設(shè)置404頁(yè)面在IIS管理器中右鍵單擊要管理的網(wǎng)站，打開“屬性”中的“自定義錯(cuò)誤信息”頁(yè)，為“404”設(shè)定相應(yīng)的錯(cuò)誤信息頁(yè)即可。不過(guò)，此處在“消息類型”中一定要選擇“文件”或“默認(rèn)值”，而不要選擇“URL”，不然，將導(dǎo)致返回“200”狀態(tài)碼。3：Apa

如何替換請(qǐng)求URL中的文字？

如何替換請(qǐng)求URL中的文字？解決方案如下，僅適用于Apache服務(wù)器。在.htaccess文件中添加以下語(yǔ)句：RewriteCond %{REQUEST_URL} "string1"RewriteRule "(.*)"string1(.*)" "$1string2$2"

網(wǎng)站改URL鏈接會(huì)降權(quán)嗎

問：有的網(wǎng)站URL太長(zhǎng)了，或者目錄太深了，或者動(dòng)態(tài)鏈接，站長(zhǎng)看網(wǎng)上的知識(shí)說(shuō)偽靜態(tài)、靜態(tài)鏈接最利于SEO，那么我可以改鏈接嗎？答：新生成的內(nèi)容，可以改URL鏈接，但是不可以影響到已經(jīng)存在的URL和已經(jīng)存在的內(nèi)容，否則會(huì)導(dǎo)致網(wǎng)站降權(quán)！來(lái)源：A5營(yíng)銷
