PageRank計算方法： PageRank是一個網(wǎng)頁的數(shù)量化度量，反映了一個網(wǎng)頁被其他網(wǎng)頁所引用的情況。PageRank算法根據(jù)一個頁面的鏈接數(shù)量和質(zhì)量來確定該頁面的相對重要性。PageRank的計算方法如下： 1. 所有頁面初始的PageRank值為1 2. 對每個頁面，計算其被其他頁面鏈接的數(shù)量和質(zhì)量，將這些值作為該頁面的權(quán)重值 3. 將這些權(quán)重值分配給該頁面鏈接到的其他頁面，以提升這些頁面的權(quán)重值 4. 反復(fù)迭代這個過程，直到收斂為止影響PageRank的因素： 1. 擁有高質(zhì)量鏈接的網(wǎng)頁更容易獲得高的PageRank值 2. 鏈接到其他高質(zhì)量的網(wǎng)頁將有利于提高網(wǎng)頁的PageRank值 3. 擁擠的鏈接頁面會削弱該頁面的PageRank值 4. 網(wǎng)頁的年齡、內(nèi)容和關(guān)鍵詞密度都可能對PageRank的計算產(chǎn)生影響 5. 與同類網(wǎng)頁比較，有獨特內(nèi)容和更高的用戶信任度的網(wǎng)頁可能獲得更高的PageRank值 6. 網(wǎng)站規(guī)模和流量也可能影響PageRank的計算，因為它們可以表示網(wǎng)站的影響力和可靠性。

Hilltop算法

HillTop ，是一項搜索引擎結(jié)果排序的專利，是Google的一個工程師Bharat在2001年獲得的專利。Google的排序規(guī)則經(jīng)常在變化，但變化最大的一次也就是基于HillTop算法進行了優(yōu)化。算法其實HillTop算法的指導思想和PageRank的是一致的，都是通過網(wǎng)頁被鏈接的數(shù)量和質(zhì)量來確定搜索結(jié)果的排序權(quán)重。但HillTop認為只計算來自具有相同主題的相關(guān)文檔鏈接對于搜索者的價值會更大

了解什么是PR

威海鏈接原理威海PR

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

如何快速提升新網(wǎng)站的PR值和外鏈

威海鏈接原理威海PR
1562

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
