robots.txt文件放在哪里?

robots.txt文件应该放在网站根目录下。举例来说，当robots访问一个网站时，首先会检查该网站中是否存在这个文件，如果机器人找到这个文件，它就会根据这个文件的内容，来确定它访问权限的范围。

网站结构有哪些类型1：什么是树状结构

我们都知道，搜索引擎喜欢的网站结构是树状结构，树状结构符合人们对知识的归类习惯。比如：图书馆的阅览室分为：自然科学阅览室、人文科学阅览室、报刊杂志阅览室。这几个阅览室内的书架又分为：自然科学阅览室：数学、物理、化学…人文科学阅览室：哲学、诗歌、小说…每个书架又会详细划分，比如数学有：高等数学、基础数学等。搜索引擎的数据库可以类比为一个超级图书馆，每个网站相当于这个超级图书馆某阅览室里的一个小书架。

robots.txt是一个网站的根目录中的文件，用于告知搜索引擎哪些页面和文件可以被搜索引擎的爬虫访问，哪些不可以。该文件是遵循 robots协议的网站必不可少的一个文件，用于控制搜索引擎的爬虫访问网站的行为。通过robots.txt文件，网站管理员可以禁止搜索引擎爬虫访问一些无用或敏感的网站内容，或是避免搜素引擎爬虫访问较为频繁的API接口等。

robots.txt文件放在哪里?

robots.txt文件通常放在网站的根目录下，即与主页文件（如index.html）同一级目录下。例如，如果网站的域名是www.example.com，那么robots.txt文件的完整路径可能是www.example.com/robots.txt。
