問題：友情鏈接可以做什么？

答案：友情鏈接做的好，可以幫助網(wǎng)站提升排名，減少降權風險，同時彼此間帶動更多的蜘蛛訪問！在SEO優(yōu)化上，雖然看似很小，但是卻是非常重要的一個環(huán)節(jié)！

百度快照都是空白的或者抓取不全是怎么回事，影響排名嗎？

前幾天有個站長問我，說網(wǎng)站很多頁面的快照都是空白的，這怎么辦，會不會影響排名！回答：快照空白肯定是會影響排名的，快照空白的主要因素如下：1、頁面太大，蜘蛛抓取困難，比如存在大量大圖，或者JS文件，或者大量文本JS。2、網(wǎng)站的服務器不穩(wěn)定，導致的抓取異常。3、頁面可能存在一些跳轉導致！4、封禁了蜘蛛！5、使用某些不靠譜的高防服務器。來源：A5營銷

網(wǎng)站降權多久能恢復

問題：網(wǎng)站降權多久能恢復回答：每一次降權都是有降權原因的，搜索引擎不會無緣無故的懲罰站點！網(wǎng)站降權后，建議先到百度站長平臺上面查看一下，近期是否有了新的算法，是否網(wǎng)站被命中算法了。之后再自我排查網(wǎng)站的問題，解決掉這些問題，視問題解決的速度，以及降權的嚴重程度，排名恢復在7-3個月不等，具體需要專門對網(wǎng)站進行綜合評估。來源：A5營銷

友情鏈接，也稱為網(wǎng)站交換鏈接、互惠鏈接、互換鏈接、聯(lián)盟鏈接等，是具有一定資源互補優(yōu)勢的網(wǎng)站之間的簡單合作形式，即分別在自己的網(wǎng)站上放置對方網(wǎng)站的LOGO圖片或文字的網(wǎng)站名稱，并設置對方網(wǎng)站的超鏈接（點擊后，切換或彈出另一個新的頁面），使得用戶可以從合作網(wǎng)站中發(fā)現(xiàn)自己的網(wǎng)站，達到互相推廣的目的，因此常作為一種網(wǎng)站推廣基本手段。友情鏈接是指互相在自己的網(wǎng)站上放對方網(wǎng)站的鏈接。必須要能在網(wǎng)頁代碼中找到網(wǎng)

與網(wǎng)址導航站交換鏈接，行嗎？

網(wǎng)址導航站，指的是分門別類展示眾多網(wǎng)址的網(wǎng)站，代表性的案例就是 hao123。加入網(wǎng)址導航站，對我們網(wǎng)站的收錄有一定的幫助。因為網(wǎng)址導航站，每天有很多搜索引擎蜘蛛在抓取，我們加入后，有機會被抓取到。有一些網(wǎng)址導航站，要求加入的網(wǎng)站必須給它們做一個友情鏈接。我們可以先百度上查看這個網(wǎng)址導航站的收錄情況，如果收錄正常，網(wǎng)站健康，則給一個友鏈，問題不大，不會帶來風險。來源：搜外網(wǎng)
