網(wǎng)絡(luò)爬蟲（Spider）

威海Spider 威海Spider

網(wǎng)絡(luò)爬蟲（Spider）是一種自動化程序，用于通過互聯(lián)網(wǎng)收集和抓取網(wǎng)頁信息。它模擬人類在瀏覽器中的操作，自動訪問網(wǎng)站并抓取其中的信息。爬蟲的主要作用是幫助用戶快速地獲取海量數(shù)據(jù)，例如網(wǎng)頁內(nèi)容、圖片、音頻、視頻等，并將它們存儲在一個本地數(shù)據(jù)庫中，以供后續(xù)處理和分析。在人工獲取數(shù)據(jù)耗時費力的情況下，網(wǎng)絡(luò)爬蟲的應(yīng)用可以大大提高數(shù)據(jù)抓取效率，以及提高數(shù)據(jù)處理的準(zhǔn)確與可靠性。

如何讓 sogou spider 不抓我的網(wǎng)站

威海Spider 威海sogou spider
2576

sogou spider 支持 robots 協(xié)議，您可以在網(wǎng)站的根目錄放置 robots.txt。robots.txt 的規(guī)則請參閱 http://www.robotstxt.org/。需要注意的是，最新更新的 robots.txt 可能需要幾個星期才能體現(xiàn)出效果來，另外，被您禁止 sogou spider 收錄的網(wǎng)頁將不能在搜狗搜索引擎上檢索到。

搜狗spider的抓取頻次是怎樣的？

sogou spider 對于同一個 IP 地址的服務(wù)器主機，只建立一個連接，抓取間隔速度控制在幾秒一次。一個網(wǎng)頁被收錄后，最快也要過幾天以后才會去更新。如果持續(xù)不斷地抓取您的網(wǎng)站，請注意您的網(wǎng)站上的網(wǎng)頁是否每次訪問都產(chǎn)生新的鏈接。如果您認為 sogou spider 對于您的網(wǎng)站抓取過快，請與我們聯(lián)系，并最好能提供訪問日志中sogou spider 訪問的部分，而不要直接將搜狗spider的ua

sogou spider 喜歡收錄什么樣的頁面？

威海Spider 威海sogou spider
3244

內(nèi)容優(yōu)良而獨特的頁面，如果您的頁面內(nèi)容和互聯(lián)網(wǎng)上已存在的其他頁面有高度的相似性，可能不會被 sogou spider 收錄。鏈接層次較淺的頁面，過深的鏈接層次，尤其是動態(tài)網(wǎng)頁的鏈接，會被丟棄而不收錄。如果是動態(tài)網(wǎng)頁，請控制一下參數(shù)的數(shù)量和URL的長度。搜狗更偏好收錄靜態(tài)網(wǎng)頁。重定向次數(shù)越多的頁面，越有可能被 sogou spider 丟棄。
