robots.txt文件有什么必要？

robots.txt文件是一個(gè)文本文件，用于向搜索引擎和其他機(jī)器人網(wǎng)站爬蟲(chóng)指定哪些頁(yè)面或內(nèi)容可以被爬取，哪些頁(yè)面或內(nèi)容不能被爬取。它的主要作用是為了控制搜索引擎和其他機(jī)器人網(wǎng)站爬蟲(chóng)訪(fǎng)問(wèn)和抓取網(wǎng)站內(nèi)容，保護(hù)網(wǎng)站的隱私和安全。如果一個(gè)網(wǎng)站不想被某些搜索引擎或爬蟲(chóng)訪(fǎng)問(wèn)、爬取和索引，就可以通過(guò)robots.txt文件來(lái)禁止它們。另外，robots.txt文件還可以防止一些機(jī)器人抓取出現(xiàn)線(xiàn)上攻擊或?yàn)E用等安全問(wèn)題。因此，對(duì)于任何一個(gè)網(wǎng)站來(lái)說(shuō)，編寫(xiě)一個(gè)有效的robots.txt文件都是非常必要的。

動(dòng)態(tài)URL是什么？動(dòng)態(tài)URL有什么特點(diǎn)？

動(dòng)態(tài)URL是指包含有會(huì)發(fā)生改變的參數(shù)的URL。它們比靜態(tài)URL會(huì)影響更大的范圍，從而獲得不同數(shù)據(jù)。動(dòng)態(tài)URL的特點(diǎn)是可以通過(guò)改變URL中的查詢(xún)字符串參數(shù)或“pathinfo”(也稱(chēng)為URL重寫(xiě))來(lái)獲得不同類(lèi)型的大量數(shù)據(jù)，從而影響整個(gè)網(wǎng)站的功能和架構(gòu)。

什么是鏈接結(jié)構(gòu)

網(wǎng)站結(jié)構(gòu)的第二意義指的是鏈接結(jié)構(gòu)，或稱(chēng)為邏輯結(jié)構(gòu)，也就是網(wǎng)站內(nèi)部鏈接形成的鏈接的網(wǎng)絡(luò)圖。比較合理的鏈接結(jié)構(gòu)通常是樹(shù)形結(jié)構(gòu)。當(dāng)然，對(duì)于搜索引擎來(lái)說(shuō)更重要的是鏈接結(jié)構(gòu)，而不是物理結(jié)構(gòu)。不少人有誤解，認(rèn)為物理結(jié)構(gòu)比較深的頁(yè)面不容易被搜索引擎收錄，比如說(shuō)：http://www.seowhy.com/cat1/cat1-1-1/pageA.html如果這個(gè)頁(yè)面在網(wǎng)站首頁(yè)上有一個(gè)鏈接，對(duì)搜索引擎來(lái)說(shuō)它就是一個(gè)

巧用robots文件管理引導(dǎo)搜索引擎蜘蛛對(duì)網(wǎng)站的抓取

許多年前，讓網(wǎng)站被搜索引擎選中包括填寫(xiě)表格，注冊(cè)該網(wǎng)站，并手動(dòng)編輯希望該網(wǎng)站被搜索的關(guān)鍵詞，這個(gè)過(guò)程隨著搜索引擎網(wǎng)絡(luò)爬蟲(chóng)或網(wǎng)絡(luò)蜘蛛的出現(xiàn)而改變。本文就robots相關(guān)內(nèi)容，做詳細(xì)的介紹。什么是搜索引擎蜘蛛？搜索引擎蜘蛛是一種自動(dòng)程序，它沿著從一個(gè)網(wǎng)頁(yè)到另一個(gè)網(wǎng)頁(yè)的鏈接在互聯(lián)網(wǎng)上爬行，為內(nèi)容編制索引并將其添加到數(shù)據(jù)庫(kù)中。這意味著，只要網(wǎng)站有一個(gè)來(lái)自其他網(wǎng)站且搜索引擎已經(jīng)知道的鏈接，然后它會(huì)找到隨著時(shí)

robots是什么？

robots是網(wǎng)站跟爬蟲(chóng)間的協(xié)議，用簡(jiǎn)單直接的txt格式文本方式告訴對(duì)應(yīng)的爬蟲(chóng)被允許的權(quán)限，也就是說(shuō)robots.txt是搜索引擎中訪(fǎng)問(wèn)網(wǎng)站的時(shí)候要查看的第一個(gè)文件。當(dāng)一個(gè)搜索蜘蛛訪(fǎng)問(wèn)一個(gè)站點(diǎn)時(shí)，它會(huì)首先檢查該站點(diǎn)根目錄下是否存在robots.txt，如果存在，搜索機(jī)器人就會(huì)按照該文件中的內(nèi)容來(lái)確定訪(fǎng)問(wèn)的范圍；如果該文件不存在，所有的搜索蜘蛛將能夠訪(fǎng)問(wèn)網(wǎng)站上所有沒(méi)有被口令保護(hù)的頁(yè)面。搜索引擎通過(guò)一
