不帶www域名重定向到帶www域名

在.htaccess文件中添加以下代碼： RewriteEngine On RewriteCond %{HTTP_HOST} !^www\. RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L] 這段代碼的作用是：首先打開(kāi)Apache的重寫引擎；然后檢查HTTP_HOST是否已經(jīng)是以"www."開(kāi)頭，如果不是，則執(zhí)行下一行代碼；最后執(zhí)行重定向操作，將不帶"www."的域名重定向到以"www."開(kāi)頭的域名。R=301表示永久重定向，L表示該規(guī)則是最后一個(gè)要執(zhí)行的規(guī)則。

nofollow標(biāo)簽的作用有重大變化

nofollow標(biāo)簽是一種發(fā)送信號(hào)給搜索引擎，表明某個(gè)鏈接并沒(méi)有推薦價(jià)值或者仍然需要被確認(rèn)，從而在搜索引擎收錄索引中減少該鏈接的收錄的技術(shù)。當(dāng)引用鏈接的頁(yè)面需要降低權(quán)重，或者是垃圾鏈接以及狗仔站點(diǎn)被引用時(shí)，采用 rel=”nofollow” 就能限制搜索引擎把這些鏈接當(dāng)做收錄的對(duì)象，達(dá)到抑制搜索結(jié)果質(zhì)量下降的目的。

url上使用#號(hào)好不好

一般來(lái)說(shuō)，url當(dāng)中的#號(hào)是一個(gè)錨點(diǎn)的標(biāo)志位，這樣的url打開(kāi)之后會(huì)將訪問(wèn)者的視線定位在指定位置上，令訪問(wèn)者直接看到網(wǎng)頁(yè)中間的一段內(nèi)容。自從推特流行開(kāi)始，#號(hào)被附予了新的意義——話題。很多站長(zhǎng)直接在#號(hào)后面加參數(shù)且參數(shù)是有效的，即#號(hào)去掉與不去掉，打開(kāi)的網(wǎng)頁(yè)完全不同。目前百度對(duì)帶#號(hào)URL的收錄策略是：去掉#號(hào)后面的內(nèi)容，僅對(duì)#號(hào)前面的url進(jìn)行建庫(kù)。這樣就導(dǎo)致一些站長(zhǎng)認(rèn)為有意義有價(jià)值的頁(yè)面，百度

怎么做301轉(zhuǎn)向

如果網(wǎng)站使用LAMP（Linux+Apache+MySQL+PHP）主機(jī)，可以使用.htaccess文件做301轉(zhuǎn)向。.htaccess是一個(gè)普通文字文件，用Notepad等文字編輯軟件創(chuàng)建和編輯，存在網(wǎng)站根目錄下。.htaccess文件中的指令用于目錄特定操作，如轉(zhuǎn)向、錯(cuò)誤處理、密碼保護(hù)等。如果網(wǎng)站用的是Windows主機(jī)，可以在控制面板做301轉(zhuǎn)向設(shè)定。純靜態(tài)HTML頁(yè)面無(wú)法做301轉(zhuǎn)向。在H

二級(jí)域名301到二級(jí)目錄算不算作弊？

二級(jí)域名301到二級(jí)目錄并不算作弊。這種做法可以有效地改變網(wǎng)站的 URL 結(jié)構(gòu)，提高網(wǎng)站的可讀性和用戶體驗(yàn)。同時(shí)，這種重定向可以幫助搜索引擎更好地索引網(wǎng)站內(nèi)容，提高網(wǎng)站的排名和流量。但是，如果頻繁更改網(wǎng)站的 URL 結(jié)構(gòu)或使用不當(dāng)?shù)闹囟ㄏ蚍绞?，?huì)導(dǎo)致搜索引擎認(rèn)為網(wǎng)站在作弊，從而影響網(wǎng)站的排名和流量。因此，在進(jìn)行二級(jí)域名到二級(jí)目錄的重定向時(shí)，應(yīng)該謹(jǐn)慎操作，避免對(duì)網(wǎng)站產(chǎn)生不良影響。
