Google Medic全面核心算法更新，發(fā)生在2018年8月，主要影響了醫(yī)療領(lǐng)域的搜索排名。這次更新主要是為了提高搜索質(zhì)量，讓高質(zhì)量的內(nèi)容更容易被發(fā)現(xiàn)，并降低非常規(guī)網(wǎng)站的排名。更新亦涵蓋了其他領(lǐng)域。這次更新改變了以往的排序規(guī)則，增加了新的排名因素，比如網(wǎng)站的歷史記錄、用戶反饋、技術(shù)優(yōu)化等。這一次更新在網(wǎng)絡(luò)營銷行業(yè)產(chǎn)生了巨大的影響，許多網(wǎng)站的排名受到明顯影響，但在更新后，優(yōu)質(zhì)的網(wǎng)站和內(nèi)容獲得了更多的流量和曝光。

Google PR劫持是一種黑客攻擊方式，指的是攻擊者通過某種手段修改了網(wǎng)站頁面的PageRank值，以提高自己的站點(diǎn)排名或降低競爭對(duì)手的排名。具體來說，攻擊者會(huì)通過篡改網(wǎng)站鏈接或利用重定向等方式，將莫名其妙的外鏈指向目標(biāo)網(wǎng)站，從而提高目標(biāo)網(wǎng)站的PR值。這種攻擊對(duì)于網(wǎng)站所有者來說是極為危險(xiǎn)的，因?yàn)樗赡軐?dǎo)致網(wǎng)站在搜索引擎結(jié)果中的排名受到影響，嚴(yán)重的甚至?xí)凰阉饕鎽土P或封禁。為了避免這種情況發(fā)生，

PageRank計(jì)算方法： PageRank是一個(gè)網(wǎng)頁的數(shù)量化度量，反映了一個(gè)網(wǎng)頁被其他網(wǎng)頁所引用的情況。PageRank算法根據(jù)一個(gè)頁面的鏈接數(shù)量和質(zhì)量來確定該頁面的相對(duì)重要性。PageRank的計(jì)算方法如下： 1. 所有頁面初始的PageRank值為1 2. 對(duì)每個(gè)頁面，計(jì)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

2006年2月4號(hào)Matt Cutts在他的博客里提到清除國際（多種語言）網(wǎng)站垃圾，也就是使用惡意作弊技術(shù)的網(wǎng)站。記不記得我前面的貼子提到，今年Google將會(huì)在清除其他國家和語言的網(wǎng)站垃圾方面投入更多的注意。這個(gè)星期我們的網(wǎng)站垃圾小組繼續(xù)進(jìn)行我們的清理垃圾工作，刪除了bmw.de（寶馬）網(wǎng)站，ricoh.de（理光）網(wǎng)站也將會(huì)因?yàn)轭愃频脑虮磺宄?。?dāng)搜索引擎訪問這個(gè)網(wǎng)頁時(shí)，它會(huì)看到這樣的網(wǎng)頁：b

Google確實(shí)已經(jīng)懲罰了Traffic Power，一次取締了其從2007年至2012年期間創(chuàng)建和使用的大量虛假外部鏈接。根據(jù)Google的網(wǎng)頁，該公司已把網(wǎng)站收錄到“反收錄列表”中，并要求搜索引擎取締Traffic Power的所有網(wǎng)站。此外，Google還對(duì)Traffic Power的網(wǎng)站施加過緊急懲罰，希望預(yù)防其網(wǎng)站盜取有價(jià)值的外部鏈接。
