robots非標準擴展協(xié)議

我不確定你所指的“robots非標準擴展協(xié)議”是什么，因為Robot協(xié)議是Web爬蟲標準協(xié)議之一，旨在告訴Web爬蟲哪些頁面可以爬取和哪些頁面不應(yīng)該被爬取。它是一個標準協(xié)議，而不是擴展協(xié)議。如果您能提供更多信息，我可以嘗試提供更詳細的回答。

網(wǎng)站物理結(jié)構(gòu)指的是網(wǎng)站真實的目錄及文件所在的位置所決定的結(jié)構(gòu)。物理結(jié)構(gòu)一般分有兩種:第一種是偏平式，也就是所以網(wǎng)頁文件都存在網(wǎng)站根目錄下。如果有很多文件放在根目錄下，制作和維護起來都比較麻煩。大中型網(wǎng)站把文件都放在根目錄下基本就無法管理了。扁平物理結(jié)構(gòu)有一個優(yōu)勢，那就是很多人認為根目錄下的文件比深層目錄中的文件天生權(quán)重高一點。第二種是樹形結(jié)構(gòu)，稱為金字塔結(jié)構(gòu)。根目錄下以目錄形式分成多個產(chǎn)品分類（頻

內(nèi)部鏈接的規(guī)則

在我們建設(shè)內(nèi)鏈的過程中應(yīng)使用HTML文本鏈接，避免使用Flash、JS代碼做內(nèi)部鏈接。因為搜索引擎蜘蛛無法良好抓取Flash、JS代碼中的鏈接。內(nèi)部鏈接的URL使用絕對地址。絕對地址的鏈接能有效解決網(wǎng)址規(guī)范化問題。絕對路徑和相對路徑對比絕對路徑(Absolute Path)指帶域名的文件的完整路徑，比如：http://seo.xxxx.com/base/231.html相對路徑(Relative

關(guān)于robots.txt的二三事

【Robots簡介】robots.txt是一個協(xié)議，是搜索引擎訪問網(wǎng)站時第一個要查看的文件，它存在的目的是告訴搜索引擎哪些頁面能被抓取，哪些頁面不能被抓取。當spider訪問一個站點時，會首先檢查該站點根目錄下是否存在robots.txt，如果存在，spider會按照文件中的內(nèi)容來確定訪問的范圍；如果該文件不存在，所有的spider將能夠訪問網(wǎng)站上所有沒有被口令保護的頁面?！揪唧w介紹】1、User

我希望我的網(wǎng)站內(nèi)容被百度索引但不被保存快照，我該怎么做？

我希望我的網(wǎng)站內(nèi)容被百度索引但不被保存快照，我該怎么做？Baiduspider遵守互聯(lián)網(wǎng)meta robots協(xié)議。您可以利用網(wǎng)頁meta的設(shè)置，使百度顯示只對該網(wǎng)頁建索引，但并不在搜索結(jié)果中顯示該網(wǎng)頁的快照。和robots的更新一樣，因為搜索引擎索引數(shù)據(jù)庫的更新需要時間，所以雖然您已經(jīng)在網(wǎng)頁中通過meta禁止了百度在搜索結(jié)果中顯示該網(wǎng)頁的快照，但百度搜索引擎數(shù)據(jù)庫中如果已經(jīng)建立了網(wǎng)頁索引信息，可
