PR是Google排名算法的200多個因素之一，而且重要性已經(jīng)下降很多。

當(dāng)然，PR還是Google排名算法中的重要因素之一。除了直接影響排名，PR的重要性還體現(xiàn)以下幾點。

（1）網(wǎng)站收錄深度和總頁面數(shù)。搜索引擎蜘蛛爬行時間及數(shù)據(jù)庫的空間都是有限的。對大中型網(wǎng)站來說，首頁PR值是帶動網(wǎng)站收錄的重要因素之一。

（2）更新頻率。PR值越高的網(wǎng)站，搜索引擎蜘蛛訪問得就越頻繁，網(wǎng)站上出現(xiàn)新頁面或舊頁面上內(nèi)容更新時，都能很快被收錄。

（3）重復(fù)內(nèi)容判定。當(dāng)Google在不同網(wǎng)站上發(fā)現(xiàn)完全相同的內(nèi)容時，會選出一個作為原創(chuàng)，其他作為轉(zhuǎn)載或抄襲。

（4）排名初始子集的選擇。初始子集的選擇顯然與關(guān)鍵詞相關(guān)度無關(guān)，而只能從頁面的重要程度著手，PR值就是與關(guān)鍵詞無關(guān)的重要度指標(biāo)。

HITS鏈接分析算法

HITS（Hyperlink-Induced Topic Search）是一種基于鏈接的搜索引擎排名算法，與其他排名算法如PageRank一樣，它的主要目的是將用戶查詢與集合的文檔匹配，使得最相關(guān)的文檔被檢索出來，排在前面。事實上，網(wǎng)頁根據(jù)網(wǎng)頁內(nèi)部和外部因素來排序。HITS算法包括兩個重要指標(biāo)：Authority和Hub，體現(xiàn)網(wǎng)頁的相關(guān)性，指導(dǎo)搜索引擎排序，即把相關(guān)性高的網(wǎng)頁排在前面。 HI

PageRank是沉迷Google的人們用來測驗其站點在Google中的排名的一種衡量規(guī)范，SEO和查找引擎營銷（SEM）專家也運用這個術(shù)語描繪網(wǎng)頁在SERP中的排名以及Google依據(jù)排名算法給予站點的分數(shù)，無論怎么界說，PageRank都是SEO的重要部分。

最近新建了一個網(wǎng)站，值所以對怎么快速提升網(wǎng)站PR的方法比較關(guān)注對于我們新手來說：在網(wǎng)站沒PR值、沒有自己的資源的情況下要想和其他PR值相對比較高的網(wǎng)站互換鏈接是不大可能的，所以還有一個渠道就是買鏈接；算是最簡便的渠道吧那如果沒有花錢買鏈呢？下面我們就這個問題探討一下！以下是對一些站長經(jīng)驗的總結(jié)：希望能對想快速提升PR的新站長有所幫助。其實提供新站PR值的方法很多，但個人總結(jié)覺得必須遵從以下幾大步驟

Google PageRank(網(wǎng)頁級別)介紹

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，PageR
