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。

URL静态化还是不静态化？

数据库驱动的网站需要将URL静态化，一直以来都是SEO最基本的要求，可以算是个常识性的东西。现在恐怕也没有不是数据库驱动的网站了吧。近几年SEO行业一致认为，URL中带2-3个问号不是问题，搜索引擎通常都能收录，尤其是权重高点的域名，更多几个问号也不是问题。但无论如何一般还是建议URL静态化。2008年9月份，Google站长博客发表了一篇讨论动态网址还是静态网址的帖子，却颠覆了这个说法。在这篇帖

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？

可以，但建议您还是提交所有网址，以确保搜索引擎对您网站的全面索引。

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ro

robots.txt文件有什么必要？

什么是robots.txt文件?搜索引擎机器人通过链接抵达互联网上的每个网页，并抓取网页信息。搜索引擎机器人在访问一个网站时，会首先检查该网站的根目录下是否有一个叫做robots.txt的纯文本文件。当我们的网站有一些内容不想被搜索引擎收录，我们可以通过设置robots.txt文件告知搜索引擎机器人。如果网站上没有禁止搜索引擎收录的内容，则不用设置robots.txt文件，或设置为空。robots
