要避免搜索引擎蜘蛛爬取某個(gè)頁面，可以在robots.txt文件中添加如下指令： User-agent: * Disallow: /index.htm 這樣，所有搜索引擎蜘蛛都不會(huì)爬取網(wǎng)站的index.htm首頁頁面。注意，這并不代表該頁面會(huì)從搜索結(jié)果中徹底移除，因?yàn)榧词箾]有被索引，用戶仍然可以在搜索結(jié)果中找到該頁面。

刪除不良頁面是否對(duì)SEO有所幫助？大多數(shù)人會(huì)有這樣的觀點(diǎn)：消除網(wǎng)站“死角”將幫助Google專注于重要的頁面。簡而言之，就是刪除一些頁面之后，我們?cè)谡军c(diǎn)地圖中向Google提交的頁面就會(huì)變得更少，而Google可以更好地專注于網(wǎng)站的重要頁面。對(duì)此，谷歌的 John Mueller 回答說：刪除頁面可能會(huì)讓其余頁面的性能變差，更少的頁面也不利于更高的排名。盲目刪除頁面甚至?xí)?duì)您的SEO效果產(chǎn)生負(fù)面影

我不確定你所指的“robots非標(biāo)準(zhǔn)擴(kuò)展協(xié)議”是什么，因?yàn)镽obot協(xié)議是Web爬蟲標(biāo)準(zhǔn)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(gè)標(biāo)準(zhǔn)協(xié)議，而不是擴(kuò)展協(xié)議。如果您能提供更多信息，我可以嘗試提供更詳細(xì)的回答。

robots簡介

搜索引擎通過一種程序robot(又稱spider)，自動(dòng)訪問互聯(lián)網(wǎng)上的網(wǎng)頁并獲取網(wǎng)頁信息。您可以在您的網(wǎng)站中創(chuàng)建一個(gè)純文本文件robots.txt，在這個(gè)文件中聲明該網(wǎng)站中不想被robot訪問的部分，這樣，該網(wǎng)站的部分或全部內(nèi)容就可以不被搜索引擎收錄了，或者指定搜索引擎只收錄指定的內(nèi)容。robots.txt(統(tǒng)一小寫)是一種存放于網(wǎng)站根目錄下的ASCII編碼的文本文件，它通常告訴網(wǎng)絡(luò)搜索引擎的漫游
