Nofollow的具體使用方法

nofollow標(biāo)簽通常有兩種使用方法：1、將"nofollow"寫在網(wǎng)頁上的meta標(biāo)簽上，用來告訴搜索引擎不要抓取網(wǎng)頁上的所有外部和包括內(nèi)部鏈接。<meta name="robots"content="nofollow" />2、將"nofollow"放在超鏈接中，告訴搜索引擎不要抓取特定的鏈接。<

nofollow的定義及如何正確使用nofollow?

什么是nofollow：　　在html標(biāo)簽中，< a > 標(biāo)簽的rel 屬性被用于說明當(dāng)前文檔與被鏈接文檔的關(guān)系。而nofollow則是其中的一種屬性值，其用法示例為：　　< a href="..." rel="nofollow" >...< /a >　　其另一種使用方法，也是最原始的使用方法，是用于網(wǎng)頁的元標(biāo)簽中，告訴搜

幾個(gè)小時(shí)前，Google官方博客發(fā)了個(gè)帖子：Evolving “nofollow” – new ways to identify the nature of links (演變中的nofollow – 判斷鏈接性質(zhì)的新方法)，公布從今天開始，nofollow標(biāo)簽的作用和Google處理nofollow的方法有了重大變化。nofollow標(biāo)簽的歷史nofollow標(biāo)簽(準(zhǔn)確說是屬性，不過約定俗成，還

Nofollow是什么意思

a：使用<nofollow>屬性的鏈接不會(huì)被搜索引擎跟蹤，更不會(huì)給鏈接傳遞權(quán)重。避免權(quán)重不必要的丟失，從而達(dá)到權(quán)重集中的目的。

網(wǎng)站Nofollow標(biāo)簽的應(yīng)用場(chǎng)景

nofollow標(biāo)簽是HTML的一個(gè)屬性，用于告訴搜索引擎不要追蹤特定的網(wǎng)頁鏈接。減少垃圾對(duì)搜索引擎的排名影響。網(wǎng)站SEO優(yōu)化nofollow標(biāo)簽的應(yīng)用起到一定的作用。網(wǎng)站Nofollow標(biāo)簽的應(yīng)用場(chǎng)景：1、nofollow標(biāo)簽通常用于論壇帖子、博客評(píng)價(jià)，這些地方存在大量的其他網(wǎng)站鏈接，導(dǎo)致網(wǎng)站上的垃圾鏈接過多，影響蜘蛛爬取，現(xiàn)在很多博客cms都會(huì)帶有相關(guān)功能自動(dòng)加上nofollow。2、給廣告鏈

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

nofollow標(biāo)簽的使用方法和作用

讀者”睡不著”在Google的數(shù)據(jù)中心們這篇帖子里留了評(píng)論，ZAC解釋一下，我在你的帖子回復(fù)里面看到說在你的博客里回復(fù)帖子簽名的鏈接可以算外部鏈接的，剛剛仔細(xì)看了一下，你的代碼a xhref=’http://www.itqy.net’ rel=’external nofollow’這樣子，根本就不能算外部鏈接的了，這樣子做是不是不太厚道??！希望ZAC出來解釋一下！要解釋這個(gè)問題不是一句兩句能說清的

nofollow是否會(huì)浪費(fèi)PR和權(quán)重？

6號(hào)寫的帖子里嘮嘮叨叨寫了好幾件之間沒什么關(guān)聯(lián)的事，其中一句是：利用nofollow控制PR流動(dòng)已經(jīng)不管用了，從一年前就不管用了。Matt Cutts前不久在SMX大會(huì)上透露了這點(diǎn)。更不妙的是，nofollow會(huì)浪費(fèi)PR和權(quán)重。也許以后博客都要關(guān)閉評(píng)論了。不過先不必輕舉妄動(dòng)。沒想到引起一些爭論，特此澄清一下。7號(hào)就看到阿里巴巴SEO國平的博客帖子，以及他在我博客的留言，他認(rèn)為我誤解了Matt Cu

Nofollow屬性的介紹和使用

什么是Nofollow？我們知道，反向鏈接是Google PR值的主要計(jì)算指標(biāo)。為了添加反向鏈接，SEO作弊者在論壇和博客等大量發(fā)布帶無關(guān)鏈接的內(nèi)容。這些垃圾鏈接的存在給搜索引擎對(duì)網(wǎng)頁質(zhì)量的評(píng)估造成一定程度的麻煩。Nofollow 正是Google、Yahoo、MSN 為了應(yīng)對(duì)垃圾鏈接（Spam）引入的一個(gè)屬性，此屬性目前應(yīng)該被廣泛采用。如果A網(wǎng)頁上有一個(gè)鏈接指向B網(wǎng)頁，但A網(wǎng)頁給這個(gè)鏈接加上了
