搜索引擎蜘蛛對(duì)于網(wǎng)站抓取是否很智能？如何引導(dǎo)蜘蛛？

盡管搜索引擎在不斷的升級(jí)算法，但是終究其還是程序，因此我們?cè)诓季志W(wǎng)站結(jié)構(gòu)的時(shí)候要盡可能的讓搜索引擎蜘蛛能看的懂。每個(gè)搜索引擎蜘蛛都有自己的名字，在抓取網(wǎng)頁(yè)的時(shí)候，都會(huì)向網(wǎng)站標(biāo)明自己的身份。搜索引擎蜘蛛在抓取網(wǎng)頁(yè)的時(shí)候會(huì)發(fā)送一個(gè)請(qǐng)求，這個(gè)請(qǐng)求中就有一個(gè)字段為User－agent，用于標(biāo)識(shí)此搜索引擎蜘蛛的身份。例如Google搜索引擎蜘蛛的標(biāo)識(shí)為GoogleBot，百度搜索引擎蜘蛛的標(biāo)識(shí)為Baidu

Baiduspider是百度搜索引擎的一個(gè)自動(dòng)程序，它的作用是訪問互聯(lián)網(wǎng)上的網(wǎng)頁(yè)，建立索引數(shù)據(jù)庫(kù)，使用戶能在百度搜索引擎中搜索到您網(wǎng)站上的網(wǎng)頁(yè)。

我希望我的網(wǎng)站內(nèi)容被搜狗索引但不被保存快照，我該怎么做？

sogou spider遵守互聯(lián)網(wǎng)meta robots協(xié)議。您可以利用網(wǎng)頁(yè)meta的設(shè)置，使搜狗顯示只對(duì)該網(wǎng)頁(yè)建索引，但并不在搜索結(jié)果中顯示該網(wǎng)頁(yè)的快照。和robots的更新一樣，因?yàn)樗阉饕嫠饕龜?shù)據(jù)庫(kù)的更新需要時(shí)間，雖然您已經(jīng)在網(wǎng)頁(yè)中通過meta禁止了搜狗在搜索結(jié)果中顯示該網(wǎng)頁(yè)的快照，但搜狗搜索引擎數(shù)據(jù)庫(kù)中如果已經(jīng)建立了網(wǎng)頁(yè)索引信息，可能需要二至四周才會(huì)在線上生效。
