鏈接深度是什么

SEO鏈接深度通俗點(diǎn)講就是網(wǎng)站內(nèi)部頁面與對(duì)方網(wǎng)站內(nèi)部頁面的鏈接，或本網(wǎng)站內(nèi)頁之間的鏈接。對(duì)于不同站點(diǎn)，這種鏈接可以是單向的內(nèi)部頁面鏈接，也可以是雙向的內(nèi)部頁面鏈接。比方說A網(wǎng)站的四級(jí)目錄頁面D可以和B網(wǎng)站的三級(jí)目錄頁面C相連。鏈接深度級(jí)別可以根據(jù)網(wǎng)站URL后面的“/”來進(jìn)行區(qū)別，如，domainA/A/B/C/D.html鏈接接到domainB/A/B/C.html，可以看成是A網(wǎng)站的四級(jí)頁面鏈接到了B網(wǎng)站的三級(jí)頁面。這樣分級(jí)后，更加容易理解鏈接深度一詞。

死鏈介紹及設(shè)置方法

一、死鏈介紹什么是死鏈幾乎所有的智能小程序或站點(diǎn)都會(huì)遇到內(nèi)容失效、過期，頁面不需要再展現(xiàn)的情況，這些無法對(duì)用戶提供任何有價(jià)值信息的頁面就是死鏈接，它包括協(xié)議死鏈和內(nèi)容死鏈兩種形式。為什么要及時(shí)處理死鏈？當(dāng)站點(diǎn)/小程序死鏈數(shù)據(jù)累積過多并且被展示到搜索結(jié)果頁時(shí)，會(huì)影響百度搜索對(duì)站點(diǎn)/小程序的評(píng)價(jià)，對(duì)站點(diǎn)/小程序的訪問體驗(yàn)和用戶轉(zhuǎn)化都會(huì)起到負(fù)面影響。另一方面，百度檢查死鏈的流程也會(huì)為站點(diǎn)/小程序帶來額外

內(nèi)部鏈接nofollow控制權(quán)重分布

Nofollow屬性推出以后，Matt Cutts多次說過，nofollow既可以用在論壇，博客等的留言中，代表這些鏈接不是站長能控制和背書的，也可以用在某些內(nèi)部鏈接，以達(dá)到控制內(nèi)部鏈接權(quán)重和PR流動(dòng)及分布的目的。最常見的應(yīng)用是在網(wǎng)站聯(lián)系我們，隱私權(quán)政策，用戶條款等鏈接上。這些網(wǎng)頁往往都是整站有鏈接，如果沒有使用nofollow，整站的鏈接權(quán)重都會(huì)平等的流動(dòng)到這些網(wǎng)頁上。而像隱私權(quán)政策這些網(wǎng)頁一般

鏈接深度是什么

鏈接深度是指從某一頁面開始往下瀏覽的頁面層數(shù)。例如，從網(wǎng)站的首頁，點(diǎn)進(jìn)一個(gè)鏈接，從該鏈接進(jìn)入了網(wǎng)站的第二層，此時(shí)的鏈接深度為2。鏈接深度有利于更好地理解網(wǎng)站的結(jié)構(gòu)，也有助于搜索引擎優(yōu)化等。
