俗話說外(wai)(wai)鏈(lian)為皇，這(zhe)(zhe)就是(shi)(shi)(shi)說明(ming)了(le)外(wai)(wai)鏈(lian)對(dui)于網站(zhan)的(de)作(zuo)用(yong)了(le)。但是(shi)(shi)(shi)很(hen)多(duo)的(de)網站(zhan)外(wai)(wai)鏈(lian)數目龐大(da)，卻不能起(qi)到有(you)效的(de)提高網站(zhan)排名(ming)權(quan)重(zhong)的(de)作(zuo)用(yong)。實則讓站(zhan)長懷(huai)疑外(wai)(wai)鏈(lian)的(de)作(zuo)用(yong)是(shi)(shi)(shi)不是(shi)(shi)(shi)有(you)這(zhe)(zhe)么大(da)的(de)作(zuo)用(yong)。其實對(dui)于外(wai)(wai)鏈(lian)并非是(shi)(shi)(shi)數量(liang)(liang)就能解決問題，甚(shen)至還有(you)因為數量(liang)(liang)的(de)關(guan)系而導致網站(zhan)被(bei)降權(quan)的(de)例子(zi)很(hen)多(duo)。所(suo)以，看(kan)外(wai)(wai)鏈(lian)的(de)作(zuo)用(yong)不單單是(shi)(shi)(shi)數量(liang)(liang)，其質量(liang)(liang)、廣泛度、相關(guan)性都(dou)比之更(geng)為重(zhong)要。今天筆(bi)者談談如何分析外(wai)(wai)鏈(lian)對(dui)排名(ming)的(de)作(zuo)用(yong)：

看外鏈是否有質量

有(you)(you)質(zhi)(zhi)量(liang)(liang)(liang)(liang)的(de)(de)外(wai)鏈(lian)(lian)可(ke)以給予(yu)網(wang)站(zhan)(zhan)莫(mo)大的(de)(de)幫(bang)(bang)助(zhu)和支持，這點是(shi)(shi)(shi)(shi)毋庸置疑的(de)(de)。而(er)(er)很多網(wang)站(zhan)(zhan)的(de)(de)外(wai)鏈(lian)(lian)數量(liang)(liang)(liang)(liang)非(fei)常(chang)的(de)(de)大，不(bu)管(guan)是(shi)(shi)(shi)(shi)個(ge)人站(zhan)(zhan)還(huan)是(shi)(shi)(shi)(shi)其(qi)(qi)他站(zhan)(zhan)，外(wai)鏈(lian)(lian)數量(liang)(liang)(liang)(liang)都(dou)是(shi)(shi)(shi)(shi)過萬的(de)(de)，但是(shi)(shi)(shi)(shi)網(wang)站(zhan)(zhan)排名(ming)卻(que)是(shi)(shi)(shi)(shi)深(shen)不(bu)見底(di)。這樣一(yi)來(lai)站(zhan)(zhan)長就(jiu)(jiu)(jiu)開始懷疑外(wai)鏈(lian)(lian)給予(yu)網(wang)站(zhan)(zhan)排名(ming)的(de)(de)作(zuo)用(yong)是(shi)(shi)(shi)(shi)否(fou)真的(de)(de)有(you)(you)那么大。其(qi)(qi)實，外(wai)鏈(lian)(lian)不(bu)看(kan)數量(liang)(liang)(liang)(liang)，而(er)(er)是(shi)(shi)(shi)(shi)看(kan)質(zhi)(zhi)量(liang)(liang)(liang)(liang)，一(yi)條質(zhi)(zhi)量(liang)(liang)(liang)(liang)鏈(lian)(lian)接可(ke)以低上二十普(pu)通外(wai)鏈(lian)(lian)。這就(jiu)(jiu)(jiu)是(shi)(shi)(shi)(shi)質(zhi)(zhi)量(liang)(liang)(liang)(liang)與數量(liang)(liang)(liang)(liang)的(de)(de)差(cha)別了。而(er)(er)且只(zhi)有(you)(you)外(wai)鏈(lian)(lian)擁有(you)(you)質(zhi)(zhi)量(liang)(liang)(liang)(liang)的(de)(de)基礎上，才能真真正(zheng)(zheng)正(zheng)(zheng)的(de)(de)幫(bang)(bang)助(zhu)網(wang)站(zhan)(zhan)提高(gao)排名(ming)權(quan)重。相反的(de)(de)，外(wai)鏈(lian)(lian)數量(liang)(liang)(liang)(liang)再多而(er)(er)沒有(you)(you)質(zhi)(zhi)量(liang)(liang)(liang)(liang)的(de)(de)可(ke)言的(de)(de)話(hua)，那么搜索引摯(zhi)只(zhi)會把它當(dang)成是(shi)(shi)(shi)(shi)網(wang)站(zhan)(zhan)的(de)(de)相關(guan)域，而(er)(er)且還(huan)是(shi)(shi)(shi)(shi)最低級的(de)(de)相關(guan)域，意(yi)思(si)就(jiu)(jiu)(jiu)是(shi)(shi)(shi)(shi)說可(ke)有(you)(you)可(ke)無的(de)(de)狀(zhuang)態。所以，看(kan)外(wai)鏈(lian)(lian)能否(fou)提高(gao)網(wang)站(zhan)(zhan)排名(ming)，那么永遠(yuan)都(dou)要記住，質(zhi)(zhi)量(liang)(liang)(liang)(liang)才是(shi)(shi)(shi)(shi)決定的(de)(de)關(guan)鍵，數量(liang)(liang)(liang)(liang)并不(bu)會影響到什么。正(zheng)(zheng)如(ru)很多站(zhan)(zhan)長看(kan)到一(yi)些網(wang)站(zhan)(zhan)的(de)(de)外(wai)鏈(lian)(lian)只(zhi)有(you)(you)寥(liao)寥(liao)無幾，但是(shi)(shi)(shi)(shi)他的(de)(de)排名(ming)卻(que)是(shi)(shi)(shi)(shi)穩如(ru)泰山，這就(jiu)(jiu)(jiu)是(shi)(shi)(shi)(shi)外(wai)鏈(lian)(lian)質(zhi)(zhi)量(liang)(liang)(liang)(liang)的(de)(de)作(zuo)用(yong)了。

看外鏈來源是否廣泛

外(wai)鏈(lian)(lian)(lian)(lian)(lian)有一(yi)(yi)(yi)(yi)個特性就是必(bi)(bi)須來(lai)(lai)源(yuan)(yuan)廣(guang)泛(fan)，因為如(ru)果(guo)(guo)天(tian)天(tian)讓蜘蛛走相同的(de)通道(dao)進(jin)入網(wang)(wang)(wang)站(zhan)(zhan)(zhan)(zhan)(zhan)，那(nei)么(me)蜘蛛的(de)興(xing)趣(qu)再好也會有厭煩的(de)一(yi)(yi)(yi)(yi)天(tian)的(de)，而(er)且(qie)來(lai)(lai)源(yuan)(yuan)過于(yu)單(dan)(dan)一(yi)(yi)(yi)(yi)對于(yu)網(wang)(wang)(wang)站(zhan)(zhan)(zhan)(zhan)(zhan)優(you)化、網(wang)(wang)(wang)站(zhan)(zhan)(zhan)(zhan)(zhan)排名都(dou)不(bu)是什么(me)好事情。畢(bi)竟如(ru)果(guo)(guo)外(wai)鏈(lian)(lian)(lian)(lian)(lian)發(fa)布(bu)平(ping)臺(tai)(tai)出(chu)問題的(de)話，那(nei)么(me)影(ying)響到(dao)自(zi)己(ji)網(wang)(wang)(wang)站(zhan)(zhan)(zhan)(zhan)(zhan)的(de)作用則是最大化的(de)，就像友情鏈(lian)(lian)(lian)(lian)(lian)接一(yi)(yi)(yi)(yi)樣，跟一(yi)(yi)(yi)(yi)個被K掉的(de)網(wang)(wang)(wang)站(zhan)(zhan)(zhan)(zhan)(zhan)互鏈(lian)(lian)(lian)(lian)(lian)，自(zi)然自(zi)己(ji)也會受(shou)到(dao)連累(lei)的(de)。所(suo)以，外(wai)鏈(lian)(lian)(lian)(lian)(lian)的(de)來(lai)(lai)源(yuan)(yuan)務必(bi)(bi)要廣(guang)泛(fan)，其實廣(guang)泛(fan)的(de)外(wai)鏈(lian)(lian)(lian)(lian)(lian)來(lai)(lai)源(yuan)(yuan)意思就是通過不(bu)同類(lei)型的(de)渠道(dao)增加(jia)外(wai)鏈(lian)(lian)(lian)(lian)(lian)數量而(er)已(yi)。比如(ru)常見的(de)外(wai)鏈(lian)(lian)(lian)(lian)(lian)來(lai)(lai)源(yuan)(yuan)地：論(lun)壇、博客(ke)、問答平(ping)臺(tai)(tai)、空間(jian)、分類(lei)信(xin)息、SNS平(ping)臺(tai)(tai)等等，這(zhe)些都(dou)可以做(zuo)為外(wai)鏈(lian)(lian)(lian)(lian)(lian)來(lai)(lai)源(yuan)(yuan)，而(er)不(bu)是單(dan)(dan)單(dan)(dan)使用論(lun)壇和博客(ke)，這(zhe)樣就會形成(cheng)外(wai)鏈(lian)(lian)(lian)(lian)(lian)來(lai)(lai)源(yuan)(yuan)單(dan)(dan)一(yi)(yi)(yi)(yi)，萬一(yi)(yi)(yi)(yi)自(zi)己(ji)的(de)號被封了，那(nei)么(me)外(wai)鏈(lian)(lian)(lian)(lian)(lian)也就失(shi)效(xiao)了。而(er)且(qie)一(yi)(yi)(yi)(yi)旦(dan)這(zhe)樣，降權K站(zhan)(zhan)(zhan)(zhan)(zhan)是無(wu)可避免(mian)的(de)。至此，從外(wai)鏈(lian)(lian)(lian)(lian)(lian)的(de)廣(guang)泛(fan)度(du)來(lai)(lai)看對網(wang)(wang)(wang)站(zhan)(zhan)(zhan)(zhan)(zhan)排名是否有作用，確實值(zhi)得廣(guang)大站(zhan)(zhan)(zhan)(zhan)(zhan)長深(shen)思啊。

看外鏈與網站是否相關

近來搜索引摯對于(yu)外(wai)(wai)(wai)(wai)鏈(lian)(lian)(lian)(lian)與網站(zhan)(zhan)(zhan)的相(xiang)(xiang)(xiang)(xiang)關(guan)(guan)(guan)(guan)性(xing)(xing)(xing)特別(bie)(bie)的注(zhu)重(zhong)，以(yi)前的那(nei)些只(zhi)要(yao)擁有(you)外(wai)(wai)(wai)(wai)鏈(lian)(lian)(lian)(lian)就(jiu)(jiu)(jiu)可以(yi)提(ti)(ti)高(gao)排名的時(shi)代過去了，而目前來說(shuo)(shuo)，外(wai)(wai)(wai)(wai)鏈(lian)(lian)(lian)(lian)與網站(zhan)(zhan)(zhan)的相(xiang)(xiang)(xiang)(xiang)關(guan)(guan)(guan)(guan)性(xing)(xing)(xing)越(yue)強，則是(shi)越(yue)容易提(ti)(ti)高(gao)網站(zhan)(zhan)(zhan)排名和權重(zhong)。而且外(wai)(wai)(wai)(wai)鏈(lian)(lian)(lian)(lian)的相(xiang)(xiang)(xiang)(xiang)關(guan)(guan)(guan)(guan)性(xing)(xing)(xing)與否(fou)，則是(shi)讓(rang)網站(zhan)(zhan)(zhan)超(chao)越(yue)對手的重(zhong)要(yao)步驟。在同樣(yang)的類(lei)(lei)型和操(cao)作下，一(yi)(yi)般外(wai)(wai)(wai)(wai)鏈(lian)(lian)(lian)(lian)的相(xiang)(xiang)(xiang)(xiang)關(guan)(guan)(guan)(guan)性(xing)(xing)(xing)越(yue)強，則排名的差(cha)別(bie)(bie)就(jiu)(jiu)(jiu)越(yue)能(neng)體現出來。所(suo)以(yi)，不管怎么說(shuo)(shuo)，外(wai)(wai)(wai)(wai)鏈(lian)(lian)(lian)(lian)與網站(zhan)(zhan)(zhan)的相(xiang)(xiang)(xiang)(xiang)關(guan)(guan)(guan)(guan)性(xing)(xing)(xing)則開始慢慢的受到(dao)站(zhan)(zhan)(zhan)長(chang)們的重(zhong)要(yao)，因為(wei)由于(yu)一(yi)(yi)些依靠(kao)外(wai)(wai)(wai)(wai)鏈(lian)(lian)(lian)(lian)的相(xiang)(xiang)(xiang)(xiang)關(guan)(guan)(guan)(guan)性(xing)(xing)(xing)成(cheng)功的網站(zhan)(zhan)(zhan)所(suo)影響，還有(you)俗話說(shuo)(shuo)的物以(yi)類(lei)(lei)聚(ju)，所(suo)以(yi)，網站(zhan)(zhan)(zhan)外(wai)(wai)(wai)(wai)鏈(lian)(lian)(lian)(lian)的相(xiang)(xiang)(xiang)(xiang)關(guan)(guan)(guan)(guan)性(xing)(xing)(xing)可以(yi)幫助網站(zhan)(zhan)(zhan)快速的提(ti)(ti)升排名，當然如(ru)果只(zhi)是(shi)依靠(kao)相(xiang)(xiang)(xiang)(xiang)關(guan)(guan)(guan)(guan)性(xing)(xing)(xing)則是(shi)不能(neng)提(ti)(ti)高(gao)排名的，但(dan)是(shi)相(xiang)(xiang)(xiang)(xiang)關(guan)(guan)(guan)(guan)性(xing)(xing)(xing)又是(shi)非常重(zhong)要(yao)的，換個角度說(shuo)(shuo)，就(jiu)(jiu)(jiu)像人們看(kan)別(bie)(bie)人的朋友(you)都結交什(shen)么類(lei)(lei)型的朋友(you)，都是(shi)以(yi)對方的生活習(xi)性(xing)(xing)(xing)來大致(zhi)猜(cai)測的，雖然有(you)時(shi)候不一(yi)(yi)定準，但(dan)是(shi)大部分都是(shi)這(zhe)樣(yang)的情況，而網站(zhan)(zhan)(zhan)外(wai)(wai)(wai)(wai)鏈(lian)(lian)(lian)(lian)也是(shi)這(zhe)樣(yang)的道理。所(suo)以(yi)說(shuo)(shuo)，外(wai)(wai)(wai)(wai)鏈(lian)(lian)(lian)(lian)的相(xiang)(xiang)(xiang)(xiang)關(guan)(guan)(guan)(guan)越(yue)強，則對排名的幫助越(yue)大。

對于網站(zhan)(zhan)外(wai)鏈(lian)以上三點進行分析(xi)其作用是(shi)(shi)最實在(zai)的(de)(de)(de)，畢竟搜索引摯對于外(wai)鏈(lian)的(de)(de)(de)看法從數(shu)量(liang)上已經轉化至質量(liang)和相(xiang)關性上了。所以，外(wai)鏈(lian)能(neng)否給予網站(zhan)(zhan)排名的(de)(de)(de)提(ti)升(sheng)，關鍵在(zai)于以上三點是(shi)(shi)否擁有，而不(bu)是(shi)(shi)靠數(shu)量(liang)來分析(xi)的(de)(de)(de)，畢竟再多的(de)(de)(de)外(wai)鏈(lian)如果沒有質量(liang)的(de)(de)(de)話，只能(neng)算是(shi)(shi)網站(zhan)(zhan)的(de)(de)(de)一條普通鏈(lian)接，根本就(jiu)無法起什(shen)么(me)風浪。
