RobotsMETA标签的写法

Robots META标签中没有大小写之分，name="Robots"表示所有的搜索引擎，可以针对某个具体搜索引擎写为name="BaiduSpider"。 content部分有四个指令选项:index、noindex、follow、nofollow，指令间以","分隔。

INDEX 指令告诉搜索机器人抓取该页面;

FOLLOW 指令表示搜索机器人可以沿着该页面上的链接继续抓取下去;

Robots Meta标签的缺省值是INDEX和FOLLOW，只有inktomi除外，对于它，缺省值是INDEX,NOFOLLOW。

这样，一共有四种组合:

<META NAME="ROBOTS" CONTENT="INDEX,FOLLOW">

<META NAME="ROBOTS" CONTENT="NOINDEX,FOLLOW">

<META NAME="ROBOTS" CONTENT="INDEX,NOFOLLOW">

<META NAME="ROBOTS" CONTENT="NOINDEX,NOFOLLOW">

其中

<META NAME="ROBOTS" CONTENT="INDEX,FOLLOW">可以写成<META NAME="ROBOTS" CONTENT="ALL">;

<META NAME="ROBOTS" CONTENT="NOINDEX,NOFOLLOW">可以写成<META NAME="ROBOTS" CONTENT="NONE">

目前看来，绝大多数的搜索引擎机器人都遵守robots.txt的规则，而对于Robots META标签，目前支持的并不多，但是正在逐渐增加，如著名搜索引擎GOOGLE就完全支持，而且GOOGLE还增加了一个指令"archive"，可以限制GOOGLE是否保留网页快照。例如:

<META NAME="googlebot" CONTENT="index,follow,noarchive">

表示抓取该站点中页面并沿着页面中链接抓取，但是不在GOOLGE上保留该页面的网页快照。

我的网站拥有几千万个网址；我可以只提交最近更改过的网址吗？

您可以在少数频繁更改的 Sitemap 中列出已更新的网址，然后使用 Sitemap 索引文件中的 lastmod 标记识别这些 Sitemap 文件。随后，百度即可逐步抓取这些已更改的 Sitemap。

网站URL显示品牌名字怎么弄

要在网站URL中显示品牌名称，您需要使用SEO优化的最佳实践和技术，例如： 1. 在网站URL中包含品牌名称。例如，如果品牌名称是"ABC"，则可以将URL设计为：www.example.com/ABC/product-name。 2. 使用301 重定向从旧URL到新URL，以确保搜索引擎能够正确地索引和显示您的品牌名称。 3. 在Meta标签中包含品牌名称，并确保它与网站内容相关且自然。

robots.txt文件的格式

"robots.txt"文件包含一条或更多的记录，这些记录通过空行分开(以CR,CR/NL, or NL作为结束符)，每一条记录的格式如下所示:"<field>:<optionalspace><value><optionalspace>"。在该文件中可以使用#进行注解，具体使用方法和UNIX中的惯例一样。该文件

Robots文件是否支持中文目录

有同学问百度站长学堂一个关于robots的问题：我们有个站点的目录结构使用的是中文，这样式儿的：www.a.com/冒险岛/123.html，那在制作robots文件和sitemap文件的时候，可以直接使用中文吗？百度能获取到吗？在实际操作中我们发现，sitemap中有文件是可以生效的，但robots封禁貌似没有反应，所以想确认一下：robots文件是否支持中文?工程师解答：Baiduspider
