在百度C2C產(chǎn)品“百度有啊”即將上線的時候，淘寶網(wǎng)站曾經(jīng)屏蔽百度搜索爬蟲，禁止百度搜索引擎抓取淘寶網(wǎng)站的網(wǎng)頁內(nèi)容，淘寶官方的解釋是“杜絕不良商家欺詐”。

在技術(shù)層面，淘寶屏蔽百度的方法是，在網(wǎng)站的robots.txt文件中加上如下內(nèi)容：

User-agent: Baiduspider

Disallow: /

但實際上這種方法并不能完全屏蔽百度的爬蟲，至今在百度上輸入site:taobao.com還是可以看到內(nèi)容，要不要索引網(wǎng)站，還是由百度說了算，要是遵守robots協(xié)議，那才不會索引，因此要想完全屏蔽百度的爬蟲，需要在.htaccess中加入一些語句才可以，下面介紹兩種方法。

方法1：

RewriteEngine on

RewriteCond %{HTTP_USER_AGENT} ^Baiduspider [NC]

RewriteRule .* - [F]

方法2：

SetEnvIfNoCase User-Agent "^Baiduspider" bad_bot

Order Allow,Deny

Allow from all

Deny from env=bad_bot

</Limit>

當(dāng)然，對于普通中文網(wǎng)站來說，還是不建議屏蔽百度的爬蟲，通常情況下做一些大型的英文網(wǎng)站，才有必要這么做，以節(jié)省流量。

我的網(wǎng)站顯示的蜘蛛抓取，有好多動態(tài)鏈接是否有影響？是否需要處理。該如何處理?11-29.123.如果不是自己網(wǎng)站本身實際存在的url，很可能是網(wǎng)站由于被人刷，導(dǎo)致的。對應(yīng)這些動態(tài)鏈接，可以在robots文件中，寫一個屏蔽抓取動態(tài)鏈接的語法。User-agent: *Disallow: /*?*更詳細的robots設(shè)置方法，可以看下面鏈接課程https://ke.seowhy.com/play/94

百度搜索引擎基礎(chǔ)知識

威海Spider 威海Baiduspider
2243

作為目前全球最大的中文搜索引擎，百度的搜索引擎資訊相關(guān)知識點如下： 1. 用戶行為數(shù)據(jù)：百度通過分析用戶搜索行為、點擊行為、停留時間等數(shù)據(jù)，分析用戶需求并為用戶提供更準確的搜索結(jié)果。 2. 索引：百度通過爬取互聯(lián)網(wǎng)上的網(wǎng)頁，將其儲存在索引庫中，用戶通過輸入關(guān)鍵詞來搜索相應(yīng)的網(wǎng)頁。 3. 算法：百度將用戶需求、網(wǎng)頁內(nèi)容、鏈接等因素綜合考慮，通過各種算法計算網(wǎng)頁的相似度和排名，為用戶提供最優(yōu)質(zhì)的
