什么是meta robots 標(biāo)簽？meta robots 標(biāo)簽的寫(xiě)法

Meta robots標(biāo)簽是一種HTML頭部元數(shù)據(jù)標(biāo)簽，用于指示搜索引擎如何處理指定頁(yè)面的內(nèi)容。它告訴網(wǎng)絡(luò)爬蟲(chóng)如何爬取索引優(yōu)化。這些標(biāo)簽是在和之間添加的，旨在為“robots（搜索引擎蜘蛛）”提供有關(guān)如何索引和緩存頁(yè)面內(nèi)容的指令。以下是meta robots標(biāo)簽的寫(xiě)法： - - - - 其中，“content”屬性指定一組用逗號(hào)分隔的值，可以是以下之一： - index：告訴爬蟲(chóng)允許索引該頁(yè)面； - noindex：告訴爬蟲(chóng)不允許索引該頁(yè)面； - follow：告訴爬蟲(chóng)允許跟隨頁(yè)面上的鏈接； - nofollow：告訴爬蟲(chóng)不允許跟隨頁(yè)面上的鏈接。

Apache IIS/.net 制作404頁(yè)面

Apache為Apache Server設(shè)置 404錯(cuò)誤頁(yè)面的方法很簡(jiǎn)單，只需：(1)在.htaccess文件中加入如下內(nèi)容：ErrorDocument 404 /notfound.php，將.htaccess文件上傳到網(wǎng)站根目錄。(2)制作一個(gè)404頁(yè)面，隨便您設(shè)計(jì)，命名為notfound.php，同樣上傳到網(wǎng)站根目錄。注意：（1）.切記不要將404錯(cuò)誤轉(zhuǎn)向到網(wǎng)站主頁(yè)，否則可能會(huì)出現(xiàn)主頁(yè)在搜索引

錨文本鏈接是什么？

錨文本鏈接是指在網(wǎng)頁(yè)上，使用一段文字或者詞語(yǔ)作為超鏈接，并且這段文字或者詞語(yǔ)是描述鏈接目標(biāo)的內(nèi)容，而不是直接使用URL地址。錨文本鏈接可以更容易地吸引到用戶(hù)的點(diǎn)擊，并且有助于提高網(wǎng)頁(yè)的搜索引擎排名。

robots.txt文件有什么必要？

什么是robots.txt文件?搜索引擎機(jī)器人通過(guò)鏈接抵達(dá)互聯(lián)網(wǎng)上的每個(gè)網(wǎng)頁(yè)，并抓取網(wǎng)頁(yè)信息。搜索引擎機(jī)器人在訪問(wèn)一個(gè)網(wǎng)站時(shí)，會(huì)首先檢查該網(wǎng)站的根目錄下是否有一個(gè)叫做robots.txt的純文本文件。當(dāng)我們的網(wǎng)站有一些內(nèi)容不想被搜索引擎收錄，我們可以通過(guò)設(shè)置robots.txt文件告知搜索引擎機(jī)器人。如果網(wǎng)站上沒(méi)有禁止搜索引擎收錄的內(nèi)容，則不用設(shè)置robots.txt文件，或設(shè)置為空。robots
