Sogou Rank與網(wǎng)頁排名關(guān)系研究

威海鏈接原理威海sogou Rank

最近對(duì)網(wǎng)站和域名的綜合權(quán)威度或重要性感受比較多，所以robin一告訴我Sogou Rank推出的消息就很感興趣。今天來做個(gè)簡(jiǎn)單的研究比較，看看Sogou Rank和真正的網(wǎng)頁排名之間的關(guān)系。我隨機(jī)挑一個(gè)關(guān)鍵詞在Sogou，百度，Google做搜索，看排在前十名的網(wǎng)頁Sogou Rank是多少。為排除大型門戶或知名服務(wù)商網(wǎng)站傳遞給二級(jí)域名及分目錄的重要性，將這些結(jié)果刪除，只看獨(dú)立的專門的網(wǎng)站。關(guān)鍵詞

最近新建了一個(gè)網(wǎng)站，值所以對(duì)怎么快速提升網(wǎng)站PR的方法比較關(guān)注對(duì)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(duì)比較高的網(wǎng)站互換鏈接是不大可能的，所以還有一個(gè)渠道就是買鏈接；算是最簡(jiǎn)便的渠道吧那如果沒有花錢買鏈呢？下面我們就這個(gè)問題探討一下！以下是對(duì)一些站長(zhǎng)經(jīng)驗(yàn)的總結(jié)：希望能對(duì)想快速提升PR的新站長(zhǎng)有所幫助。其實(shí)提供新站PR值的方法很多，但個(gè)人總結(jié)覺得必須遵從以下幾大步驟
