根據(jù)預(yù)測,2009年Google PR值的第一次更新應(yīng)該會在10天內(nèi)的3月27日,10天后再查看是否更新。有人說是2009年第一次更新發(fā)生在單獨下降google日本的懲罰上。還有人說google已經(jīng)開始提前清算部分違規(guī)網(wǎng)站。
根據(jù)預(yù)測,2009年Google PR值的第一次更新應(yīng)該會在10天內(nèi)的3月27日,10天后再查看是否更新。有人說是2009年第一次更新發(fā)生在單獨下降google日本的懲罰上。還有人說google已經(jīng)開始提前清算部分違規(guī)網(wǎng)站。以下是轉(zhuǎn)載的2000年以來google pr值的歷次更新:
*其中TBPR Export指google工具條接口數(shù)據(jù)更新,GDPR Export指Google Directory接口數(shù)據(jù)更新,BL Export指反向鏈接數(shù)據(jù)更新。
*Google PageRank 是 Google 衡量網(wǎng)頁重要性的一個指標(biāo),其值從0到10共分為11個等級,其數(shù)值越大,說明這個網(wǎng)頁也就越重要。當(dāng)然,想要升的越高,其難度也就越大,由于 PR值算法保密,我們無從知曉影響PR值的具體算法;但是許多網(wǎng)友根據(jù)各種跡象,推測出了一些關(guān)于 Google PageRank 的秘密。
