2.搜索引擎收录限制及要求：
| 搜索引擎收录要求及限制–Search Engine Indexing Limits | ||
|---|---|---|
| *以下规则并不适合所有引擎 | ||
| 网页文件大小 | 大小不可以超过150kb；去除图片、Css、及其他页面附件文件 | |
| 链接数量 | 每个网页页面最多不允许超过100个链接。 | |
| 标题标记Title Tag | 做多不允许超过70个字节； | |
| 描述关键字 | 最多不允许超过155个字节； | |
| URL链接参数 | 最多参数不应操作两个 | 错误的使用方法:
http://www.mysite.com/brands.php? object=1&type=2&kind=3&node=5&arg=6 |
| 正确的使用方法:
http://www.mysite.com/brands.php?nike |
||
| Depth of URL | 最深不应超过4级 | 错误的使用方法:
http://www.mysite.com/people/places/things/ noun/danny/car |
| *Best Practice
正确的使用方法: http://www.mysite.com/people/danny/ |

| Apache服务器30重定向方法 | |
|---|---|
|
在apache配置文件里面的‘mod_rewrite’方法为启用状态下时；在主机的根目录下面，新建一个名为‘.htaccess’的文件；此文件为配置服务器路径重写文件① |
|
| 命令 | 描述 |
| Redirect 301 /oldpage.html http://www.newdomain.com/
newpage.html |
Redirect single file or directory to a new
file or directory on a different domain |
| RewriteEngine on
RewriteCond %{HTTP_HOST} ^mysite.com [NC] RewriteRule (.*) http://www.mysite.com/$1 [L,R=301] |
Redirect http://mysite.com to http://
www.mysite.com. Affects entire domain. |
| Entire site:
Redirect 301 / http://www.newdomain.com/ Redirect permanent /old http://www.newdomain.com/new |
Redirect entire domain to a new domain
as either a 301 (recommended) or 302 |
- .htaccess为在linux的主机下面或者VPS的主机下面特有的支持文件；将此文件放置在主机的顶级目录后，方可开启服务器的重写功能，并且在启用mod_rewrite的文件下；虚拟路径重写如：（www.abc.com/home/index.html）.
