Google PageRank是一個用于評估網(wǎng)頁重要性的算法。它是Google搜索引擎的一個重要部分，用于確定搜索結(jié)果頁面的排名。PageRank算法根據(jù)網(wǎng)站的鏈接數(shù)量、鏈接質(zhì)量和其他因素來確定網(wǎng)站的重要性和權(quán)威性。 PageRank算法是基于網(wǎng)頁鏈接結(jié)構(gòu)來評估網(wǎng)頁重要性的。它將網(wǎng)頁的價值評估為其相關(guān)頁面的數(shù)量和質(zhì)量的函數(shù)。具有高PageRank值的頁面通常位于搜索結(jié)果的前幾頁。因此，PageRank對于網(wǎng)站擁有者和網(wǎng)絡(luò)市場營銷人員來說非常重要，他們希望他們的網(wǎng)站位于搜索結(jié)果的最前面，以便吸引更多的流量和潛在客戶。 PageRank是一種非常復(fù)雜的算法，它綜合考慮了許多因素，包括鏈接質(zhì)量、鏈接數(shù)量、網(wǎng)站內(nèi)容的質(zhì)量、網(wǎng)站的年齡和其他因素。雖然PageRank已經(jīng)過時，但它仍然是搜索引擎優(yōu)化中一個基本的概念。

Matt Cutts談PR和PR更新

威海鏈接原理威海PR

大家都注意到前兩天Toolbar(工具條)PR已經(jīng)更新了。Matt Cutts發(fā)了一個帖子，回答一些關(guān)于PR和PR更新的問題。問：我很好奇PR值在內(nèi)部是怎樣存儲的？是小數(shù)，就像人們猜測的，還是整數(shù)？答：把它想為小數(shù)更準(zhǔn)確。當(dāng)然目前我們內(nèi)部的PR計(jì)算比toolbar顯示的0－10要長的多。問：我需要知道這個嗎？我知道PR能告訴我什么，我為什么要在乎？也就是說對普通網(wǎng)站來說，PR有什么目的？答：我想這

TrustRank算法

TrustRank是一種基于Web搜索的信息檢索技術(shù)，用于挖掘有質(zhì)量的網(wǎng)頁，并將其置于搜索結(jié)果的頂部。它可以準(zhǔn)確地將有質(zhì)量的網(wǎng)頁與搜索詞相關(guān)聯(lián)，從而過濾掉某些無關(guān)的鏈接，讓有質(zhì)量的網(wǎng)頁出現(xiàn)在搜索結(jié)果中。 TrustRank算法通過跟蹤搜索引擎向用戶展示的鏈接的信譽(yù)來確定搜索結(jié)果的順序。同時它會檢測用戶的反饋，比如點(diǎn)擊量，瀏覽時間，以及用戶評價，用于調(diào)整頁面排列順序。這樣的話，用戶就可以更加準(zhǔn)

Google PR 值是什么？怎樣計(jì)算？

威海鏈接原理威海PR

相信對SEO感興趣的人，都聽說過Google PR值，英文全稱是PageRank，縮寫為PR，中文通常稱為網(wǎng)頁級別。所謂Google PR，是由 Google的兩位創(chuàng)始人Larry Page 和 Sergey Brin 在斯坦福大學(xué)開發(fā)的衡量網(wǎng)頁重要性的一個指標(biāo)。樸素的思路是，一個網(wǎng)頁導(dǎo)入鏈接越多，頁面應(yīng)該就更重要，所以PR值就越高。PR可以理解為頁面之間的投票行為，網(wǎng)頁A鏈接到網(wǎng)頁B時，Goog

Google PR劫持

威海鏈接原理威海PR
783

Google PR劫持是指惡意攻擊者修改網(wǎng)站的PageRank值，以使其在Google搜索結(jié)果中獲得更高的排名。攻擊者可以通過篡改網(wǎng)站內(nèi)容、利用漏洞或使用黑帽SEO技術(shù)等方式來實(shí)現(xiàn)PR劫持。這種攻擊可能會導(dǎo)致合法網(wǎng)站的訪客數(shù)量銳減，進(jìn)而影響其商業(yè)利益。為了避免PR劫持，網(wǎng)站管理員應(yīng)當(dāng)做好網(wǎng)站安全防護(hù)工作，及時更新網(wǎng)站補(bǔ)丁和加強(qiáng)網(wǎng)站訪問控制等措施。
