搜索引擎蜘蛛劫持是seo黑帽中常用的一種手法,需要一定的技術(shù)支持getshell,然后上傳惡意的代碼到網(wǎng)站根目錄下面或者修改網(wǎng)站的一些文件，搜索引擎蜘蛛劫持的原理就是判斷來訪網(wǎng)站的是用戶還是蜘蛛,如果是蜘蛛就推送一個事先準(zhǔn)備的惡意網(wǎng)站,如果是用戶就推送一個正常的網(wǎng)頁

1：蜘蛛判斷

判斷訪問的是用戶還是蜘蛛,如果是用戶就推送一個正常網(wǎng)頁,如果是蜘蛛就推送一個惡意網(wǎng)頁，判斷方式有兩種,一種是判斷蜘蛛的UA,一種是蜘蛛的ip段

2:蜘蛛劫持代碼

判斷如果是百度,360,搜狗,神馬蜘蛛就返回惡意的網(wǎng)頁給蜘蛛，如果不是就返回www.shangeedu.com網(wǎng)站的內(nèi)容,注意編碼是utf-8還是其它的

Baiduspider對一個網(wǎng)站服務(wù)器造成的訪問壓力如何？

為了達(dá)到對目標(biāo)資源較好的檢索效果，Baiduspider需要對您的網(wǎng)站保持一定量的抓取。我們盡量不給網(wǎng)站帶來不合理的負(fù)擔(dān)，并會根據(jù)服務(wù)器承受能力，網(wǎng)站質(zhì)量，網(wǎng)站更新等綜合因素來進(jìn)行調(diào)整。如果您覺得baiduspider的訪問行為有任何不合理的情況，您可以反饋至反饋中心。

網(wǎng)站抓取了一些不存在的目錄跟頁面?

可能是因?yàn)榫W(wǎng)站存在未處理的URL鏈接或者被其他網(wǎng)站或者搜索引擎誤解導(dǎo)致的，也有可能是惡意的爬蟲在嘗試攻擊網(wǎng)站。為了解決這個問題，可以通過以下方式進(jìn)行： 1. 對于不存在的頁面，應(yīng)該返回404錯誤頁面或者301重定向到一個已有的頁面； 2. 建立一個robots.txt文件來限制搜索引擎或者爬蟲的訪問； 3. 定期檢查日志文件來發(fā)現(xiàn)存在攻擊性的IP地址或者爬蟲； 4. 部署防火墻、權(quán)限管理和加密措

如何提高spider抓取網(wǎng)站？提高spider抓取策略（2）

威海Spider 威海Spider

1. 增加抓取頻率：可以通過減少抓取的時間間隔來提高 spider 的抓取頻率，但需要注意不要過度頻繁抓取，否則會給網(wǎng)站帶來過大的訪問壓力。 2. 使用代理 IP：使用代理 IP 可以幫助 spider 繞過網(wǎng)站的訪問限制，提高抓取成功率。 3. 模擬人工操作：模擬人工操作可以讓 spider 更像真實(shí)用戶，例如瀏覽網(wǎng)頁、點(diǎn)擊鏈接等，可以提高抓取成功率。 4. 優(yōu)化抓取路徑：優(yōu)化抓取路徑可以
