robots文件中屏蔽的為什么還可以收錄？

我今天來給大家詳細(xì)講解下，先了解幾個(gè)概念

1、robots只是禁止抓取，不是禁止收錄

2、另外還有nofollow的作用不是不抓取這個(gè)鏈接，是不從這個(gè)鏈接傳遞權(quán)重

了解這2個(gè)概念后，我們?cè)賮碛懻撛趺刺幚磉@類收錄問題：

robots寫正確的同時(shí)，不要在任何一家收錄的網(wǎng)站發(fā)外鏈，友鏈，也不要主動(dòng)提交百度，這樣才可以保證不被搜索引擎收錄，為什么呢？

大家百度查一下淘寶，如圖：

按照道理淘寶寫了robots怎么還是收錄，因?yàn)橛写罅康逆溄又赶蛱詫毠倬W(wǎng)，而且這些外鏈可能權(quán)重都比較高，

全部都禁止了，依然收錄了1億多條鏈接

看到這里，是不是有感而發(fā)，我們?cè)趺磸陌俣葘?dǎo)流到你的淘寶店！（來源：夫唯seo特訓(xùn)營）

Apache為Apache Server設(shè)置 404錯(cuò)誤頁面的方法很簡(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，否則可能會(huì)出現(xiàn)主頁在搜索引

nofollow標(biāo)簽的作用有重大變化

自nofollow標(biāo)簽于2005年推出以來，其作用一直是指示搜索引擎不要追蹤鏈接。這項(xiàng)功能主要用于避免垃圾郵件和鏈接操縱，因?yàn)槟承┱军c(diǎn)會(huì)通過在其他站點(diǎn)上發(fā)布大量鏈接來提高其搜索引擎排名。nofollow標(biāo)簽的作用是告訴搜索引擎不要將鏈接計(jì)入其評(píng)估算法。然而，隨著SEO和數(shù)字營銷的發(fā)展，nofollow標(biāo)簽的作用已經(jīng)發(fā)生了重大變化?，F(xiàn)在，nofollow標(biāo)簽不僅能夠阻止鏈接被計(jì)入搜索引擎的排名算

?robots是什么？robots mate和?robots有什么區(qū)別

robots是什么robots是網(wǎng)站跟蜘蛛間的協(xié)議，當(dāng)訪問站點(diǎn)時(shí)，它首先檢查機(jī)器人是否存在于站點(diǎn)的根目錄中。如果找到，蜘蛛就會(huì)按照該文件中的內(nèi)容來確定訪問的范圍,如果該文件不存在,那么搜索機(jī)器人就沿著鏈接抓取。一定要注意txt文件必須放在站點(diǎn)的根目錄中，文件名必須為小寫。robots.txt是一個(gè)純文本文件，在這個(gè)文件中網(wǎng)站管理者可以聲明該網(wǎng)站中不想被搜索引擎訪問的部分，或者指定搜索引擎只收錄指定

Robots META標(biāo)簽的寫法

如果您想讓搜索引擎忽略某些網(wǎng)頁，可以使用"robots" META標(biāo)簽。以下是這種標(biāo)簽的寫法： ```html ``` 上述標(biāo)簽將告訴搜索引擎不要索引或跟蹤該網(wǎng)頁。下面是一些其他常見的指令： - "index" 將指令搜索引擎索引該頁面。 - "follow" 將指令搜索引擎跟蹤此頁面上的鏈接。 - "noindex" 將指令搜索引擎不要索引此頁面。 - "nofollow" 將指令搜索引擎
