robots使用技巧

以下是一些使用robots.txt文件的技巧和最好的做法： 1. 不要放弃robots.txt - 一些网站管理员没有robots.txt文件，因为他们认为这是保护网站的安全措施，但事实上它可能会影响搜索引擎爬取。 2. 维护一个更新的robots.txt文件 - 确保您的robots.txt文件不是过时的。如果您从网站上删除了某些页面或文件夹，请务必更新文件以反映更改。 3. 不要使用robots.txt来隐藏私人或敏感信息 - robots.txt文件不应该用于隐藏个人信息，如登录页面或敏感数据。如果您希望它们得到安全保护，最好使用其他安全措施。 4. 逐个声明规则 - 避免声明一大堆规则，而是按需要分开声明，以便搜索引擎更好地理解您的规则。 5. 警惕错误 - 如果您不熟悉robots.txt文件的语法或规则，最好使用在线工具来帮助您检测和修复可能的错误。 6. 不要使用禁用所有规则 - 避免声明禁用所有页面和机器人的规则。这些规则会阻止搜索引擎爬取您的网站，从而影响您的搜索引擎排名。 7. 深度限制 - 使用“深度”选项声明可以访问的文件夹层数，以帮助搜索引擎减少遍历您的网站的时间。 8. 关注机器人 - 使用“User-agent”选项指定要检查的机器人类型，并在需要时声明特定的规则。

网站文章内链的一个思路

内链：顾名思意就是在自己网站的内容中的相关文字加入链接，并且链接到网站内部的相关页面。合理的网站内空链接构造，能提高搜索引擎的收录与网站权重。相对外部链接，内部链接也很重要。传统方式以前我们做文章系统或新闻发布系统的时候，做文章内链（标签）的时候，通常是通过以下方式来实现的：数据库：article（文章表）字段（id， title， body， adddate， userid），keyword（内

什么是robots文件
