什么是robots文件

Robots是站點(diǎn)與spider溝通的重要渠道，站點(diǎn)通過robots文件聲明本網(wǎng)站中不想被搜索引擎收錄的部分或者指定搜索引擎只收錄特定的部分。

搜索引擎使用spider程序自動(dòng)訪問互聯(lián)網(wǎng)上的網(wǎng)頁(yè)并獲取網(wǎng)頁(yè)信息。spider在訪問一個(gè)網(wǎng)站時(shí)，會(huì)首先會(huì)檢查該網(wǎng)站的根域下是否有一個(gè)叫做 robots.txt的純文本文件，這個(gè)文件用于指定spider在您網(wǎng)站上的抓取范圍。您可以在您的網(wǎng)站中創(chuàng)建一個(gè)robots.txt，在文件中聲明該網(wǎng)站中不想被搜索引擎收錄的部分或者指定搜索引擎只收錄特定的部分。

請(qǐng)注意，僅當(dāng)您的網(wǎng)站包含不希望被搜索引擎收錄的內(nèi)容時(shí)，才需要使用robots.txt文件。如果您希望搜索引擎收錄網(wǎng)站上所有內(nèi)容，請(qǐng)勿建立robots.txt文件。
