使用nofollw的意義，nofollw標簽的兩種具體用法

使用nofollw的意義

nofollow 是一個HTML標簽的屬性值。它的出現(xiàn)為網(wǎng)站管理員提供了一種方式，即告訴搜索引擎"不要追蹤此網(wǎng)頁上的鏈接"或"不要追蹤此特定鏈接。這個標簽的意義是告訴搜索引擎這個鏈接不是經(jīng)過作者自己編輯的，所以這個鏈接不是一個信任票。

簡單的說就是，如果A網(wǎng)頁上有一個鏈接指向B網(wǎng)頁，但A網(wǎng)頁給這個鏈接加上了 rel="nofollow" 標注，則搜索引擎不把A網(wǎng)頁計算入B網(wǎng)頁的反向鏈接，搜索引擎看到這個標簽就可能減少或完全取消鏈接的投票權(quán)重。

nofollw標簽的兩種具體用法

1、將"nofollow"寫在網(wǎng)頁上的meta標簽上，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。

2、將"nofollow"放在超鏈接中，告訴搜索引擎不要抓取特定的鏈接。

要實現(xiàn)301跳轉(zhuǎn)，可以按照以下步驟操作： 1. 確認被重定向的頁面或網(wǎng)站已經(jīng)關(guān)閉或不再使用。 2. 在服務(wù)器上創(chuàng)建一個 .htaccess 文件，或者使用已經(jīng)存在的 .htaccess 文件。 3. 在 .htaccess 文件中添加代碼： Redirect 301 /原網(wǎng)址 http://新網(wǎng)址其中，“原網(wǎng)址”是你想重定向的頁面或者網(wǎng)站的網(wǎng)址，而“新網(wǎng)址”是你想

我希望我的網(wǎng)站內(nèi)容被百度索引但不被保存快照，我該怎么做？

我希望我的網(wǎng)站內(nèi)容被百度索引但不被保存快照，我該怎么做？Baiduspider遵守互聯(lián)網(wǎng)meta robots協(xié)議。您可以利用網(wǎng)頁meta的設(shè)置，使百度顯示只對該網(wǎng)頁建索引，但并不在搜索結(jié)果中顯示該網(wǎng)頁的快照。和robots的更新一樣，因為搜索引擎索引數(shù)據(jù)庫的更新需要時間，所以雖然您已經(jīng)在網(wǎng)頁中通過meta禁止了百度在搜索結(jié)果中顯示該網(wǎng)頁的快照，但百度搜索引擎數(shù)據(jù)庫中如果已經(jīng)建立了網(wǎng)頁索引信息，可

頁面有多個鏈接指向同一個頁面會分散權(quán)重嗎？是否加nofollow？

威海seo專題威海nofollow
2800

一個頁面有多個鏈接指向同一個頁面這樣有沒有分散權(quán)重的影響？需不需要給其中一個加上nofollow？就像默認的站內(nèi)站標題和下面閱讀全文都是這篇文章的鏈接。11-22.你自己需要判斷這些鏈接是否有權(quán)重傳遞的必要，有就不用，沒有就加上。關(guān)于是否nofollow，取決于該鏈接對應(yīng)的頁面是否有需要獲取排名的關(guān)鍵詞?；蛘哒f，該鏈接是否有必要獲得權(quán)重的傳遞。加上nofol

nofollow標簽的作用有重大變化

nofollow標簽最初是由Google引入的，旨在告訴搜索引擎跟蹤鏈接的方式。它的作用是讓網(wǎng)站管理員控制搜索引擎是否跟蹤某個鏈接并傳遞權(quán)重。也就是說，如果一個頁面包含了nofollow標簽，搜索引擎就不會將該頁面與被鏈接的頁面相關(guān)聯(lián)，也不會將該頁面作為鏈接目標的一部分考慮。這樣可以避免一些不必要的鏈接傳遞權(quán)重，同時可以防止人工操縱搜索引擎排名。然而，隨著時間的推移，nofollow標簽的作用
